Receiving device for synchronous serial transmission data

摘要

A receiving device for synchronous serial transmission data includes a transmission path for transmitting data synchronized to clock signal according to a bit serial system; a shift register for holding the data transmitted in series; and an operating device executing an operation on a bit-by-bit basis between first data provided by the shift register and second data received at the shift register. The operating device performs the operation between the first data and the second data on a bit-by-bit basis at the same time that the second data are received, without requiring a save register having the capacity to store the entire data size.
