example 1

[0104] Example 1 includes an electronic device comprising a substrate, and logic coupled to the substrate for determining a reference value to compress a block of data, wherein the block of data consists of a first number of data words , replacing the original values ​​of a second number of data words from the data block with respective delta values ​​from the reference value to provide compressed data, wherein the second number of data words is greater than the first number of data words There are at least two less data words, and metadata associated with the data block is stored in the data block along with the compressed data.

example 2

[0105] Example 2 includes the apparatus of example 1, wherein the logic is further configured to set one or more data index fields in the metadata to indicate that the data block is used in relation to the reference value. The respective positions of the data words replaced by the respective delta values.

example 3

[0106] Example 3 includes the apparatus of any one of examples 1-2, wherein the logic is further to identify a data word from the data block having a data value suitable for the reference value, and to convert the The reference value is set to the data value of the identified data word.

Abstract

The present disclosure generally relates to low complexity coverage based compression. An embodiment of an electronic device may include a substrate, and logic coupled with the substrate to determine a reference value to compress a block of data, where the block of data is composed of a first number of data words, replace original values of a second number of data words from the block of data with respective difference values from the reference value to provide compressed data, wherein the second number of data words is at least two less than the first number of data words, and storing metadata associated with the data block in the data block along with the compressed data. Other embodiments are disclosed and claimed.

Description

technical field [0001] The present disclosure generally relates to low-complexity coverage-based compression. Background technique [0002] Error-correcting code (ECC) memory is a type of computer data storage device that detects and corrects many types of internal data corruption. In general, ECC memory makes the memory system immune to one or more bit errors. In ECC memory, the data read from each word is the same as the data that was written to it, even if one or more bits actually stored in the ECC memory are flipped to the wrong state. A syndrome table is a mathematical way of identifying bit errors and then correcting them, and the syndrome space can be used in such syndrome-based decoding. [0003] ECC memory is used to provide reliability for applications that cannot tolerate data corruption. ECC memory can consist of additional devices on dual in-line memory modules (DIMMs) that provide additional ECC storage, as well as data channels so that ECC information can ...
