Abstract
A high performance graphics applications controller having a core processor and a coprocessor to independently perform desired graphics functions is provided. The core processor and the coprocessor divides processing tasks to speed execution and to reduce the burden on the host CPU. A direct memory access (DMA) controller cooperates with the coprocessor to generate source and destination addresses and employs a unique set of commands to speed operation. The core processor employs a local CPU and data and address catches to locally perform desired graphics operations independently but in conjunction with the coprocessor. The present invention has particular application with smart terminals and wherever pixel oriented data is required.
