International Classification:

G11C 2900

US Classification:

714718, 365201

Abstract:

A system and method for testing memory systems in accordance with the present invention increases efficiency and reduces initial diagnostic and power up time for microprocessor-based units. The method includes copying a test process sequence into a memory system; updating an address indicative of the segment of the memory system being tested; comparing the address to an end of memory system address; copying the test process sequence to a next block of the memory system, and iterating through the method until the addresses are equal and the end of the memory system is reached.

Abstract:

A system and method for compressing and decompressing a binary code image includes preprocessing the image to separately group together the operation codes and the operands that make up the binary code image into a columnar format. The resultant preprocessed data is then compressed using any one of a plurality of compression codes. In turn, the resultant compressed image may be stored in a memory element or transferred using a transmission channel to a different device. The compressed image is then decompressed to reconstruct the binary code image.
