COUPLER FOR PROCESSORS

摘要

The system has two computers (1,2) sharing one memory (3) using an access control (7). The access control is coupled to the first computer (1) via a first access request line (8) and via a first access acknowledge line (9) and to the second computer via a second access request line (10) and a second access acknowledge line (11). The control disconnects the one computer from the memory on receipt of that computer's access acknowledge signal, where it disconnects that computer and connects the other computer to the memory.
