I have a project (enclosed here as RS_ECC) that creates parity data for a given block of input data (512 bytes) using the common Reed-Solomon algorithm. I need a function written that will decode (i.e. correct) the data if a bit or two are corrupted. The function prototype should look like this: int Decode(Int32[] msgdata, Int[] parity_syms) The result should be as follows: 0 = NoErrors //all bits and parity match 1 = Correctable //one or more bits dont match but was corrected 2 = EccError //the error is in the ecc 3 = Uncorractable //more errors than are correctable For example, using the enclosed project and the test file ("[login to view URL]"), I can create the parity data like: byte() sub_data = [login to view URL]; //(512 bytes) [login to view URL](512, 4, 9); //init the class with 512 byte blocks, 4-bit correction, and 9-bit wide symbols. int() result = [login to view URL](sub_data); The result data returned is (keep in mind each result is 9-bits wide): result(0) = 0x044 result(1) = 0x058 result(2) = 0x0EC result(3) = 0x1A9 result(4) = 0x056 result(5) = 0x123 result(6) = 0x1BB result(7) = 0x031 So if a bit is changed in the [login to view URL], when you run it through the Decode function, it would correct the bit and then return (1). Please read this entire project before posting a bid. There are several open-source projects with examples of RS decoding, so any of them that you can use to work with the provided example will be acceptable.
