THE DEVICE OF INFORMATION COMPRESSION (DIC)
The enterprise has developed the device of the
information compression (DIC), intended for parallel
performance of operation of compression of the
dataflows acting on 4-channels. Compression of the
information is realized on the basis of modified cosine
transformations in real time with factor of
a compression up to 5. The compressed information is
supplemented with Read-Solomon codes.
Entrance dataflows act on the 8-bit entrance trunk, in
byte-serial mode, with the maximal speed of 23,04 MB
per second (for each of 4 channels). IC represents
multiprocessor system on TMS320C67xx base
(channels of compression) and on TMS320C54xx
base(the processor of management).
Into structure of DIC enters:
· channels of compression - 4;
· the reserve channel of compression;
· the processor of management;
· the reserve processor of management;
· a power unit;
· a reserve power unit.
