Abstract
An architecture for providing hardware compression/decompression with ECC to data flow in a computer system utilizes a hardware implementation of the compression/decompression circuit in a peripheral adapter of one of many peripheral devices. Error correction coding is provided by software in the host RAM. The compression/decompression circuit can be located in the periphery and can service a number of peripheral devices. The CPU and DMA controller in the host computer are capable of providing concurrent processing for hard disk operation, peripheral control (such as a tape or a modem), compression/decompression of data, and error correction coding of the compressed data. This significantly speeds up the performance of the computer system.
