A raster image graphics subsystem (10) for an acoustic console, or other console requiring sensor and/or graphics imagery, employs extensive parallelism and modularity to enhance performance and flexibility. Parallel specialized image cogenerators (14) respond to commands from graphics and acoustic processors to draw representations of image in bit map memories (16) via an image bus (26). A display controller (20) accesses these representations via a video bus (12) which provides for various mappings of bit map memories to the display controller. Multiple images can be displayed on a single monitor (22) using viewporting techniques managed by a viewport controller (24). New functions and increased throughput can be added to the subsystem by adding additional cogenerators. |
