Bit shift compression
WebAug 27, 2014 · 3. I want to compress a file that looks like a BITMAP INDEX. (A file that is in binary format with "0" and "1" only). When using a byte to represent "0" or "1" the compression has a good ratio, because of the low randomness. Instead of using a byte to represent a "0" or "1" i would like to use a bit. Example: number 8 = 00001000 numbeer … Although most machines are not able to address individual bits in memory, nor have instructions to manipulate single bits, each bit in a word can be singled out and manipulated using bitwise operations. In particular: • OR to set a bit to one: 11101010 OR 00000100 = 11101110 • AND to set a bit to zero: 11101010 AND 11111101 = 11101000

It typically compresses numeric floating-point values better and faster than other algo-rithms do. On our data sets, it achieves compression ratios between 1.2 and 4.2 as well as compression and decompression throughputs between 2.8 and 5.9 million 64-bit dou-
WebLempel–Ziv–Welch (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch.It was published by Welch in 1984 as an improved implementation of the LZ78 algorithm published by Lempel and Ziv in 1978. The algorithm is simple to implement and has the potential for very high throughput in … WebThe Bitwise Complement. The bitwise complement operator, the tilde, ~, flips every bit. A useful way to remember this is that the tilde is sometimes called a twiddle, and the …
