Microprocessor data compression algorithm

  • How does compression algorithm work?

    Compression algorithms are normally used to reduce the size of a file without removing information.
    This can increase their entropy and make the files appear more random because all of the possible bytes become more common..

  • What are the two types of compression algorithm?

    What are the two types of data compression? There are two methods of compression – lossy and lossless.
    Lossy reduces file size by permanently removing some of the original data.
    Lossless reduces file size by removing unnecessary metadata..

  • Which algorithm is used for data compression?

    In the mid-1980s, following work by Terry Welch, the Lempel–Ziv–Welch (LZW) algorithm rapidly became the method of choice for most general-purpose compression systems.
    LZW is used in GIF images, programs such as PKZIP, and hardware devices such as modems..

  • Which is the method of data compression?

    What is the compression technique in data compression? There are broadly two types of data compression techniques—lossy and lossless.
    In lossy, the insignificant piece of data is removed to reduce the size, while in lossless compression, the data is transformed through encoding, and its size is reduced..

  • LZ77 algorithms achieve compression by replacing repeated occurrences of data with references to a single copy of that data existing earlier in the uncompressed data stream.
  • ZIP is an archive file format that supports lossless data compression.
    A ZIP file may contain one or more files or directories that may have been compressed.
    The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
We describe two algorithms based on the scan-along polygonal approximation algorithm (SAPA) that are suitable for multichannel ECG data reduction on a  

What is cache compression?

IEEE Trans.
Info.
Theory 24, 5 (1978), 530–536.
Cache compression is a promising technique to increase on-chip cache capacity and to decrease on-chip and off-chip bandwidth usage.
Unfortunately, directly applying well-known compression algorithms (usually implemented in software) leads to high ..

Is a cache compression algorithm based on pattern matching and partial dictionary coding?

This paper has proposed and evaluated an algorithm for cache compression that honors the special constraints this application imposes

The algorithm is based on pattern matching and partial dictionary coding

Is there a cache compression algorithm similar to C-Pack?

Many prior system-wide cache compression results hold,provided that they use a compression algorithm with characteristics similar to C-Pack

This paper has proposed and evaluated an algorithm for cache compression that honors the special constraints this application imposes

What is C-Pack in microprocessor performance?

C-PACK: CACHE COMPRESSION FOR MICROPROCESSOR PERFORMANCE Abstract—Computer systems and micro architecture researchers have proposed using hardware data compression units within the memory hierarchies of microprocessors in order to improve performance, energy efficiency, and functionality
