PARALLEL PROCESSING OF BIT STREAM

摘要

PURPOSE: To perform the fast communication control by receiving in series the bit streams arriving during a time interval T and assembling these bit streams in order to process (n) pieces of continuous bits in parallel to each other. CONSTITUTION: A CCU(central control unit) 1 executes a network control program and is connected to a CPU(central processing unit) 3 via a bus 2. An adaptor 5 secures an interface between the user lines 6-1 to 6-i and a serial link 7 and also secures adaptation of the bit streams existing on the user lines to a specific form or its inverse form defined on the link 7. A line scan means 4 has a character service function device 8 which receives the HDLC/SDLC bit streams from the user lines to produce the N-bit characters. These produced characters are offered to the upper layer of the means 4. The device 8 also receives the N-bit characters from the upper layer of the means 4, and these characters are converted into the HDLC bits and sent to the user lines.
