Abstract
An information processing apparatus which processes a large amount of data at high speed. The synchronizing signal has a cycle including a transfer period and a processing period. In the transfer period, data is transferred, e.g., from a data input unit to a first memory, and from the first memory to a second memory. In the processing period, the data input unit reads data for one frame of a digital video image, and a data output unit displays an image based on the image data. Processors respectively perform predetermined processing upon data stored in a memory connected to the processor. Thus, within one cycle of the synchronizing signal, processing is completed at respective stages from input to output. Note that the connection between the memories and the processors may be changed for performing the processing at the respective stages without data transfer. In this case, data transfer time can be saved.
