Abstract
A processing system is provided that includes an external device connected to a processor. The external device has the capability of responding to external device commands wherein each of these external device commands is performed within at least one fixed time cycle. The processor provides these external device commands and, further, includes the means for executing instructions that not only specify the external device commands but also specify at least one internal command to be performed by the processor simultaneously with the performance of the external device command and within the same fixed time cycle. In the disclosed embodiment, a graphics display system is provided that includes a system processor, a graphic processor, a graphics memory and a display device. The graphics processor receives instructions from the system processor which specifies commands to be executed by both the graphics processor and the graphics memory. Each graphics memory command is executed within a fixed time cycle simultaneously with the execution of a corresponding graphics processor command executed within the graphics processor.
