Method and apparatus for rendering lines |
摘要 |
A bitblt and line draw parameter calculator for preprocessing address information for a bitblt and line draw sequencer. The sequencer computes individual pixel addresses, controls color 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.
