Title: Microcomputer
Inventor: ITO SAKAE
IPC: G06F9/38
Filed: 1987-10-27
Abstract: PURPOSE:To facilitate the testing itself of a microcomputer having a pre-fetching function by providing a means to judge whether a pre-fetching function is made effective or ineffective. CONSTITUTION:When the command of a fetching cycle is given from a central part 8 to a control part 7, an address signal corresponding to the reading address of a memory is generated by an address generating part 6. An address signal is sent through an address bus AB to the memory and the data in the memory are fetched through a data bus DB to an instruction queue 4. In the central part 8, it is judged by the data impressed from the bus DB whether the pre-fetching function of an instruction is made effective or in-effective. When the pre-fetching function is made in-effective, and the contents of the queue 4 are 1 byte or below, a pre-fetching action is not executed. Consequently, at the time of testing a peripheral function part, the pre-fetching function does not function and a testing is facilitated.
