Pulse input unit

Abstract

Abstract PURPOSE:To make efficient the production of integrated data of input pulse and the data transfer with CPU, by giving the memory corresponding to each input channel and counting the input pulses every channel. CONSTITUTION:The data processing section 12 gives the access signal to finish all the scannings for n-channels within the time T to each channel of 1-n to fetch the input signal value of each channel. When the input signal value changes from 0 to 1, the content of the memory address in the data processing section 12 corresponding to the channel is added by +1. The data transfer and control section 14 receives the data transfer request from CPU and after the designation of the address of the memory 13 corresponding to the channel requested, data transfer request is made to the data processing section 12.
