ABSTRACT:
A graphics system is disclosed within which video graphics images are calculated via a computer and output for storage via a buffer whereby the image can be compressed/expanded for storage in compressed form in a dedicated semiconductor memory. The system also permits storage of compressed images on hard disk by directly connecting the compressed image store to a system bus. The compressed image store can be duplicated and further compression/expansion units added to broaden system versatility. Alternatively, a single compression/expansion unit can be used.
