Pipelinestrukturen für vollfarbfähigen Rechnergraphik

摘要

A graphics system (50) is disclosed within which video graphics images are calculated via a computer (11) and output for storage via a buffer (55, 56) whereby the image can be compressed/expanded (57, 58) for storage in compressed form in a dedicated semiconductor memory (59). The system (50) also permits storage of compressed images on hard disk (12) by directly connecting (64) the compressed image store (59,63) to a system bus (7). The compressed image store (19) can be duplicated (217, 218) and further compression/expansion units (213, 214, 215) added to broaden system versatility. Alternatively, a single compression/expansion unit (301) can be used.
