Series signal reception system

Abstract

Abstract PURPOSE:To store received data without exclusively using a system bus by performing storing and reading out while successively changing over the two storage circuits prepared for storage only of the received data by every received data. CONSTITUTION:The 1st data of a series signal is inputted from a terminal SD to a series to parallel conversion circuit 1, from which parallel data is outputted. It is stored into the storage address of a storage circuit 3 assigned by a storage address generating circuit 6 through a selection circuit 2. Upon completion of the storage of the 1st data, the circuit 2 connects the output of the circuit 1 and a storage circuit 6 to a storage circuit 4, and a selection circuit 5 connects a system bus terminal Sb to the circuit 3. When the 2nd data is inputted, it is stored in the storing address of the circuit 4 assigned by the circuit 6 through the circuit 2. Upon completion of the storage of the 2nd data, the circuit 2 connects the output of the circuit 1 and the circuit 6 to the circuit 3 and the circuit 5 connects to the circuit 4 by the system bus terminal Sb.
