Title: Data processor

IPC: G06F1/08
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To process data at processing speed suitable for input data and to reduce unwanted power consumption in simple configuration by inputting the input data through a memory means and varying reading speed and processing speed by varying a clock corresponding to the amount of data stored in this memory means. SOLUTION: A FIFO 21 successively inputs image data D1 with a system clock SCK as a reference and outputs these data synchronously with a clock CK1 outputted from a clock control circuit 23. At such a time, when the amount of stored image data is decreased rather than 1/2 of capacity, the FIFO 21 outputs a remaining amount increase signal EMP1. With the clock CK1 as a reference, an arithmetic module 4 successively fetches the image data D1 outputted from the FIFO 21. With the remaining amount increase signal EMP 1 as a reference, the clock control circuit 23 varies the frequency of the clock CK1. Thus, the processing speed of the arithmetic module 4 is varied so that the amount of image data stored in the FIFO 21 can be 1/2 of capacity.
