<p>PURPOSE:To shorten the time to execute a given program by using a single chip microprocessor which contains a memory circuit to hold temporarily the data to be written to a main memory. CONSTITUTION:An instruction of a microprocessor 1 gives a command as a part of its command contents to write the data already existing within the processor 1 at a time point when the writing should be executed to a certain address of a main memory 3. Under such conditions, the corresponding data is stored in a memory circuit 6 and held there. One of features of this processor 1 is a control means that executes the above-mentioned action. The circuit 6 is provided with plural units, and each unit contains an address part and a data part. Therefore a unit having coincidence between the contents of the address part and the corresponding address is designated by providing an address. Then the data is written to the data part of the relevant unit, and at the same time the data can be read out of the data part.</p> |
