Computer graphics system.

摘要

A computer graphics system having a bitblt and line draw parameter calculator for preprocessing address information for a bitblt and line draw sequencer 320. The sequencer computes individual pixel addresses, controls colour interpolation pacing and communicates with the memory hypervisor. By partitioning memory addressing into two tasks a first line or bitblt need only be partially processed prior to starting processing on a second line or bitblt.
