摘要 |
A communication controller integrated into a data processing system comprising a central processing unit (1) with a main control storage (3) and a local storage (2), the system further comprising a number of high speed adapters (6-10) connected to the central processing unit by means of a high speeds bus (5), the high speed adapters serving a plurality of input/output devices. At least one of the high speed adapters is a high speed bus adapter (7) controlling over a low speed bus (12) a number of low speed communication line adapters (11, 15-19). All microcodes for controlling the operation and diagnostic of the various communication lines (20) is located in a communication control storage (4) in the main control storage (3). |
