ABSTRACT:
The multiplexing character processor of the present invention multiplexes data characters to and from a plurality of communication lines to a Central Processing Unit by bit slicing. Input data present on the plurality of communication lines is sampled at a rate which is at least 16 times the data bit rate and is formulated as a serial data bit stream. Each sample corresponds to a time slice which slice is allocated to a given communication line under the control of a scan list. A high data rate communication line can be placed on the scan list more than once to insure accurate data reproduction. Character assembly and disassembly is performed in an arithmetic logic unit (ALU) under program control, to provide the flexibility to support various communication link protocols. The input data on each communication line may have a different protocol. Synchronization of the serial data bits to the communication lines is performed by a data bit synchronizer DBS.
