Image processing apparatus for processing digital signals
First Claim
1. An image processing apparatus connected to external machines for inputting data therefrom to a plurality of image memories and outputting data from said plurality of image memories thereto comprising:
- a plurality of memory access controllers connected to said plurality of image memories;
control means for selecting;
a first mode for said plurality of memory access controllers to access said image memories separately;
or a second mode for a master controller, which is one of said memory access controllers, to access said plurality of image memories as one image memory space so as to control said plurality of memory accessan area signal generator for outputting an area signal indicating that data on a data bus is valid based on a control signal input from the external machine.
