Control Processor Module
The Control Processor Module (Figure 3-2) has overall control of the
system. All of the control and interface functions originate here. There are
two microprocessors and associated circuitry on the module.
The 68302 I/O processor handles the following:
■
The system boot
■
The operating system
■
The external interface
■
The watchdog timer
The 68020 state processor handles the following:
■
The reading and writing between the control panel and the signal
processor frame
■
Calculations necessary to do the video functions
■
Reading system configuration
