If you require wider information support, contact me. For Software functions, information stream is certainly sliced into portions starting from Flow0 char where each piece contains amount of pieces established by the information width field. After that MSB-LSB is applied to the sliced pieces. For Hardware modules, information stream is usually fed to the component as slices that consists of bits driven by the data width industry. The user has to slice the information stream into pieces. If the information width is usually fixed to be better than 1, insight data pieces are prepared in the order chosen by this field.

I deliberately avoided making use of MSB/LSB, still left almost all/right nearly all, endianness terms to prevent misunderstandings (including myself). The generated module will simply accept insight data as an assortment of pieces (for SW) or a register (for HW) and assortment/register catalog has no ambiguity regardless of the language or HW/SW.

This industry affects both calculator code era and on the internet computation as it determines the information input direction of the primary calculator code. For on-line computation, there is certainly an extra filed that can choose how the real input flow is sliced up and given to the primary calculator program code. Data stream that the selected poylnomial be used to generate a CRC result. If the LFSR will be selected, the input data can be disregarded. The result signifies the value produced by thé LFSR after oné pass. If the information width is usually fixed to become higher than 2, after that the input data is certainly processed in information width chunks and the input data must be multiples of the information width. Insight information can become got into in binary, decimaI or hexadecimal structure.

Introduction on CRC calculations

Whenever digital data is stored or interfaced, data corruption might occur. Since the beginning of computerscience, people have been thinking of ways to deal with this type of problem. For serial data they came up withthe solution to attach aparity bitto each sent byte.This simple detection mechanism works if an odd number of bits in a byte changes, but an evennumber of false bits in one byte will not be detected by the parity check. To overcome this problem people havesearched for mathematical sound mechanisms to detect multiple false bits. The CRC calculationor cyclic redundancycheck was the result of this. Nowadays CRC calculations are used in all types of communications. Allpackets sent over a network connection are checked with a CRC. Also each data block on your harddisk has a CRCvalue attached to it. Modern computer world cannot do without these CRC calculation. So let's see why they are sowidely used. The answer is simple, they are powerful, detect many types of errors and are extremly fast to calculateespecially when dedicated hardware chips are used.

One might think, that using a checksum can replace proper CRC calculations. It is certainly easier to calculatea checksum, but checksums do not find all errors. Lets take an example string and calculate a one byte checksum.The example string is 'Lammert' which converts to theASCIIvalues[ 76, 97, 109, 109, 101, 114, 116 ]. The onebyte checksum of this array can be calculated by adding all values, than dividing it by256 and keeping theremainder. The resulting checksum is 210. You can use the calculator above to check this result.

In this example we have used a one byte long checksum which gives us256 different values. Using a two byte checksum willresult in 65,536 possible different checksum values and when a four byte value is used there are more than fourbillion possible values. We might conclude that with a four byte checksum the chance that we accidentily donot detect an error is less than 1 to 4 billion. Seems rather good, but this is only theory. In practice, bitsdo not change purely random during communications. They often fail in bursts, or due to electrical spikes.Let us assume that in our example array the lowest significant bit of the character'L' is set, and the lowest significant bit of charcter 'a' is lost during communication.The receiver will thansee the array[ 77, 96, 109, 109, 101, 114, 116 ]representing the string 'M`mmert'.The checksum for this newstring is still 210, but the result is obviously wrong, only after two bits changed. Even if we had useda four byte long checksum we would not have detected this transmission error. So calculating a checksum may bea simple method for detecting errors, but doesn't give much more protection than the parity bit, independent ofthe length of the checksum.

The idea behind a check value calculation is simple. Use a function F(bval,cval) that inputs one data byteand a checkvalue and outputs a recalculated check value. In fact checksum calculations as describedabove can be defined in this way. Our one byte checksum example could have been calculated with the followingfunction (in C language) that we call repeatedly for each byte in the input string. The initial value forcval is 0.

The idea behind CRC calculation is to look at the data as one large binary number. This number is dividedby a certain value and the remainder of the calculation is called the CRC. Dividing in the CRC calculation at first looks tocost a lot of computing power, but it can be performed very quickly if we use a method similar to the onelearned at school. We will as an example calculate the remainder for the character'm'—which is 1101101 in binary notation—by dividing it by 19 or10011. Please note that 19 is an odd number. This is necessary as we will see further on.Please refer to your schoolbooks as the binary calculation method here is not very differentfrom the decimal method you learned when you were young. It might only look a little bit strange. Alsonotations differ between countries, but the method is similar.

With decimal calculations you can quickly check that 109 divided by 19gives a quotient of 5 with 14 as the remainder. But whatwe also see in the scheme is that every bit extra to check only costs one binary comparison andin 50% of the cases one binary substraction.You can easily increase the number of bits of the test data string—for example to 56 bits if we use our examplevalue 'Lammert'—and the result can be calculated with 56 binary comparisons and an average of 28binary substractions. This can be implemented in hardware directly with only very few transistors involved. Alsosoftware algorithms can be very efficient.

For CRC calculations, no normal substraction is used, but all calculations are done modulo 2.In that situation you ignore carry bits and in effect the substraction will be equal to an exclusive oroperation. This looks strange, the resulting remainder has a different value, but from an algebraic point of viewthe functionality is equal. A discussion of this would need university level knowledge of algebraic field theoryand I guess most of the readers are not interested in this. Please look at the end of this document for books thatdiscuss this in detail.

Now we have a CRC calculation method which is implementable in both hardware and software and also has a morerandom feeling than calculating an ordinary checksum. But how will it perform in practice when oneore more bits are wrong? If we choose the divisor—19 in our example—to be anodd number,you don't need high level mathematics to see that every single bit error will be detected.This is because every single bit error will let the dividend change with a power of 2. If for examplebit n changes from 0 to 1, the value of the dividend will increase with 2n. If on theother hand bit n changes from 1 to 0, the value of the dividend will decrease with2n. Because you can't divide any power of two by an odd number, the remainder of the CRC calculationwill change and the error will not go unnoticed.

The second situation we want to detect is when two single bits change in the data. This requires some mathematicswhich can be read in Tanenbaum's book mentioned below. You need to select your divisor very carefully to besure that independent of the distance between the two wrong bits you will always detect them. It is known, thatthe commonly used values 0x8005 and 0x1021 of the CRC16 and CRC-CCITT calculations performvery good at this issue. Please note that other values might or might not, and you cannot easily calculate which divisorvalue is appropriate for detecting two bit errors and which isn't.Rely on extensive mathematical research on this issue done some decades ago by highly skilled mathematiciansand use the values these people obtained.

Furthermore, with our CRC calculation we want to detect all errors where an odd number of bit changes. This can be achieved by using adivisor with an even number of bits set. Using modulo 2 mathematics you canshow that all errors with an odd number of bits are detected. As I have said before, in modulo 2 mathematicsthe substraction function is replaced by the exclusive or. There are four possible XOR operations.

We see that for all combinations of bit values, the oddness of the expression remains the same. When chosing adivisor with an even number of bits set, the oddness of the remainder is equal to the oddness of the divident.Therefore, if the oddness of the dividend changes because an odd number of bits changes, the remainder willalso change. So all errors which change an odd number of bits will be detected by a CRC calculation which is performed withsuch a divisor. You might have seen that the commonly used divisor values 0x8005 and 0x1021 actually havean odd number of bits, and not even as stated here.This is because inside the algorithm there is a 'hidden' extra bit 216 whichmakes the actual used divisor value 0x18005 and 0x11021 inside the algorithm.

Last but not least we want to detect all bursterrors with our CRC calculation with a maximum length to be detected, and all longer burst errors to be detected with a high probability.A burst error is quite common in communications. It is the type of error that occurs because of lightning,relay switching, etc. where during a small period all bits are set to one. To really understand this you also needto have some knowledge of modulo 2 algebra, so please accept that with a 16 bit divisor you will beable to detect all bursts with a maximum length of 16 bits, and all longer bursts with at least 99.997%certainty.

In a pure mathematical approach, CRC calculation is written down as polynomial calculations. The divisor valueis most often not described as a binary number, but a polynomial of certain order. In normal life some polynomialsare used more often than others. The three used in the on-line CRC calculation on this page are the16 bit wide CRC16 and CRCCCITT and the 32 bits wide CRC32. The latter is probably most used now, becauseamongst others it is the CRC generator for all network traffic verification and validation.

For all three types of CRC calculations I have afree software libraryavailable. The test program can beused directly to test files or strings. You can also look at the source codes and integrate these CRC routinesin your own program. Please be aware of the initialisation values of the CRC calculation and possible necessarypostprocessing like flipping bits. Zodiac pb4 60 polaris booster pump. If you don't do this you might get different results than other CRCimplementations. All this pre and post processing is done in the example program so it should be not to difficultto make your own implementation working. A common used test is to calculate the CRC value for theASCIIstring'123456789'. If the outcome of your routine matches the outcome of the test program or the outcome on thiswebsite, your implementation is working and compatible with most other implementations.
