performance of lz77 compression on large random array
I have a large array of raw bytes. The byte array does not follow any patter and the byte values can be any value (random).The size of the array is 45000x5x400 bytes. And I have 1 second to encode. Will lz77 be feasible? And how should I choose the look up dictionary? Also what will be a good choice for number of bits to hold the relative index and the match length ?
