ABSTRACT:
A data processing system includes a microprocessor and a memory coupled to each other, and has a burst access function in which, when an active burst request signal is supplied to the memory, only a first address is outputted to the memory, so that a plurality of items of data are accessed sequentially from the first address. A memory region of the memory is divided into a plurality of memory blocks, and the microcomputer includes a register for storing burst access/single access information for each of the memory blocks, and a decoder receiving an address to be outputted to the memory for knowing to which memory block a memory region to be accessed belongs. When the memory region to be accessed is a memory block for the burst access, a burst request signal is activated.
