Accessing memory in HDLC communications protocol hardware machine system with server

摘要

The processor has the function of emulating the operation of a number of independent transmitter and receiver modules. The machine has an HDLC server (10) that consists of the HDLC machine (12), a microprocessor (14) and a RAM memory. The HDLC machine has three sub-systems, i.e. address logic (50), control logic (70) and an address generator (90). The microprocessor is a universal type with ports for input and output functions. The system operates to access the system memory and to analyse segments of data.
