Embodiment Construction

[0046] Dynamic real-time data compression chip, including original data input line port DD0-DD7, compressed data line port DB0-DB7 and memory address line port q0-q18, and a latch S is connected with the original data input line port to latch The output terminal of the device is connected with the non-gate U31-U38, and the chip also includes an adder J, the input terminal of the adder is respectively connected to the original data input line ports DD0-DD7 of the chip and the non-gate U31-U31-U31 connected to the output terminal of the latch. The output terminals B0-B7 of U38 are connected, and the output terminals C0-C7 of the adder are divided into two parallel circuits, one of which enters the input terminal of the OR gate U2 through the OR gate U1 and the NOT gate U3, and the other channel enters the other input terminal through the NAND gate U4 The end is the OR gate U5 of ERR CON, and then enters the input end of the OR gate U2 through the NOT gate U23. The line terminals ...

Abstract

A dynamic real-time data compression chip includes data input port, data storage port and address port, a latch connected with input port and its output end connected with NOT gate, an adder with its input end connected with the data input port of the chip and the output end of NOT gate which is connected to the output of the latch respectively, and tristate gate, redundant counter and address counter which are controlled by the output end signal of the adder. The said data compression chip can compress the dynamic data in real time and whether each specimen point is stored or not just has the relationship only with the previous specimen point of the said specimen point and the rules of the testing margin of error, and no relationship with the later specimen point of the said specimen point.

Description

technical field [0001] The invention relates to an information processing technology, in particular to a dynamic data information compression technology, specifically a dynamic real-time data compression chip. Background technique [0002] Data compression technology is a widely used information processing technology, which has extremely wide applications in aerospace, communication, meteorology and other fields. It occupies an extremely important position in data storage technology. [0003] Most of the existing data compression technologies are to compress known data, that is, the data objects to be compressed must be known at the time of compression, and a data model and algorithm are extracted from these known data, and then according to this model and algorithms to recode known data for storage or transmission. The popular MPEG video and audio compression and the compression of data files by WINZIP in the WINDOWS environment all belong to this category. This principl...
