| abstract | PURPOSE: To improve an operation efficiency as a whole by operating asynchronously plural function modules whose maximum operation frequencies are different, and also, executing a synchronized control for a data transfer between the function modules. n CONSTITUTION: A single chip microcomputer 1 incorporates a CPU module 2, a RAM module 3, a timer counter module 4, a serial input/output circuit module 5, a DMAC module 6 and a DMAC module 7. In this state, to the modules 2, 3, 4, 6 and 7, different operation clock signals ϕ 0 , ϕ 3 , ϕ i , ϕ 1 and ϕ 2 are supplied through a frequency dividing circuit 11 from the output of a clock pulse generator 10 to which an external clock signal CLK1 and the modules execute an asynchronous operation. To the input/output circuit module 5, an independent clock signal CLK2 is applied and a data transfer which passes through a silicon pack plane bus 8 being an asynchronous bus is brought to synchronized control. In such a manner, the operation efficiency as a whole can be improved. n COPYRIGHT: (C)1990,JPO&Japio |
