<p>PURPOSE:To improve the processing efficiency of jobs by causing an instruction register or instruction decoder to receive instructions from a program and send signals to a frequency divider circuit to change the frequency division rate of clocks. CONSTITUTION:On one chip, clocks from clock oscillator 1 are frequency-divided by N variable 1/N frequency divider circuit 2, and clocks from circuit 2 are generated in polyphase by polyphase clock generator 3. Here, instruction register 4 and instruction decoder 5 receive instructions from a program and send them to circuit 2 to change the frequency division rate of clocks. As a result, the processing efficiency of jobs can be improved.</p> |
