Function

4-level priority bus arbiter

Power-on reset/front panel reset

System clock and serial clock generator

Bus timeout generator

8 28-pin sockets for EPROM/RAM

Global Interrupter

During normal operation, the MVME-050 provides all the system controller functions required for a VMEbus system.

For time access, the system software reads the time from the time clock. The system software can use two serial ports to connect to a terminal, modem or data link.

Hardcopy output is available through a Centronics-type printer port.

The EPROM/RAM socket can be used as general system memory, or to hold debug and/or diagnostic programs and scratchpad RAM.

In many multiprocessor systems, it is desirable for a process executing on one MPU module to interrupt a process executing on another MPU module.

The Global Interrupter (complete with signaller) provides this global interrupt capability.
