ABSTRACT:
An image compression system has an image memory accessible from the image bus. Compressed data are stored in a dual-ported memory accessible from both the image bus and the host bus. The compressor/expander accesses the image memory while the host accesses the dual-ported memory. Dual-ported memory allocation schemes and a computer program controlling the image compression system are also provided.
