LIST
;=======================================================================
; CARD DECK IDENTIFICATION NUMBER: CR/C/0106
; MODULE IDENTIFICATION: NIC/210
; VERSION: 0301
; DATED: 780321/FR,HQH
;
; OPERATIONAL SUBMODULE MULTIPLEXER CPU INTERFACE (MXI)
;
; THE MXI SUBMODULE CONSISTS OF TWO PROCESSES BOTH OF WHICH RUN
; MASKED WHILE UPDATING THEIR RESPECTIVE CDT/CST-RECORDS.
;
; . A CPU-INTERRUPT-DRIVEN
; THE PURPOSE OF THE CPU INTERRUPT DRIVEN PROCESS IS TO SERVE THE
; MUX-CPU GENERATED CPU INTERRUPTS REQUESTING THE COM-CPU TO SERVE
; THE BY THE MUX-CPU CREATED MQI/MQO'S (MESSAGE QUEUES) THROUGH
; WHICH SUPPLYING AND REMOVAL OF BINS FOR THE MUX IS CONTROLLED.
; THE MXI WILL SERVE THE MUX WITH EMPTY BINS FOR INPUT DATA AND
; FULL BINS FOR OUTPUT DATA. THE DIFFERENT STATUS CHANGES REPORTED
; BY THE MUX WILL BE TRANSFERRED TO THE CST FOR LATER RETRIEVAL.
;
; . A LETTER-DRIVEN
; THE PURPOSE OF THE LETTER DRIVEN PART OF THE MXI IS TO HANDLE
; THE LTU RELATED SUBCOMMANDS ISSUED TO THE CMI SUBMODULE, I.E.
; THE SETUP, OPENING, AND CLOSING OF CHANNELS AS WELL AS PART OF
; THE PRE-EMPTION.
; LETTERS ARE DISPATCHED TO THIS SUBMODULE FROM
; . COMMAND INTERPRETER SUBMODULE
; . OUTPUT DATA PROCESSING SUBMODULE
;
; N B THE MUX PSW MUST (AND WILL BE) 2#011
;
; N O T E IN ORDER FOR THE CPU INTERRUPT DRIVEN PROCESS TO SERVE
; THE MQI/MQO'S SENT FROM THE MUX-CPU PROPERLY IT WILL HAVE
; TO RUN AT A HIGHER (S/W) PRIORITY LEVEL THAN THE LETTER
; DRIVEN PROCESS.
;
; THE SYNCHRONEOUS EDC BLOCK PROTOCOL IS NOT IMPLEMENTED.
