Abstract:
A picture processing apparatus comprising:a CPU for carrying out processing; a memory for storing processing results produced by the CPU and for storing data to be displayed; a display control circuit for making accesses to the memory and for controlling an operation to display the data stored in the memory; a processing circuit for completing processing within a prescribed time by making accesses to the memory to read out the data to be displayed; and a bus control circuit for arbitrating a contention for an access to the memory between the display control circuit and the processing circuit; wherein the display control circuit and the processing circuit each include means for outputting an internal-state signal representing an internal state thereof; and wherein the bus control circuit determines which of the display control circuit and the processing circuit is to be given a higher priority to make an access to the memory based on the internal-state signals output by the display control circuit and the processing circuit.
