Title: Microcomputer
Inventor: FUJIMURA YOSHIHIDE
IPC: G06F1/04
Filed: 1991-07-04
Abstract: PURPOSE:To reduce the power consumption by composing a clock selection flag of an EEPROM when plural system clock oscillation circuits are present. CONSTITUTION:When a CPU 2 writes '1' in the clock selection flag 7, a clock selecting circuit 6 selects a subsystem clock and supplies an operation clock of low frequency to the microcomputer 1. In this case, the flag 7 is composed of the electrically writable and erasable ROM(EEPROM). Consequently, the value of the flag never varies unless the CPU 2 rewrites a value. Therefore, once the flag 7 is set to '1', this microcomputer 1 begins to operate with the subsystem clock of low frequency even when a reset signal or even in a power-ON resetting state.

Filed: 1989-06-26
Abstract: PURPOSE:To improve the throughput by varying the interval from a read of each process instruction of one step of a parallel processing program to a read of each process instruction of a next step according to an external command. CONSTITUTION:This data processor consists of a memory 19 stored with the parallel processing program consisting of plural process insutruction sequences, a control means 18 which read process instruction of the parallel processing program out of the memory, step by step, and generates instruction signals corresponding to the read process instructions and a processing means 21 which executes data processing operation corresponding to the respective instruction signals. Further, the control means 18 has an adjusting means 21 which adjusts the interval from a read of each process instruction of one step to a read of each process instruction of a next step according to the external command. Therefore, a program where a few instructions NOP are inserted can be generated. Consequently, the throughput is improved without increasing the capacity of the program memory 19.
