nto RF533 series controller subracks.
The Motorola 68040 processor is a 32-bit virtual memory microprocessor with
an integrated floating point unit and with dual independent instruction and data
demand paged memory management units (MMUs). It also has two separate
4 kbyte caches, one for data and one for instructions.
The dynamic RAM memory is organized as a 64-bit memory with an 8-bit
cyclic redundancy check sum.
The module has a Futurebus+ type interface with 32-bit address/data lines
supporting compelled transfers.
Distributed arbitration is used. Arbitration messages are supported.
To support a configuration with two redundant processor modules with one
running in backup mode, PM511V is equipped with logic that transfers a copy
of all writes in the primary processor to the backup processor, thereby keeping
a complete updated copy of the primary processor’s memory in the backup pro-
cessor. This makes it possible for the backup processor to resume the
operation directly in the event of a failing primary processor.
The module front has LED indicators for status information, a start mode selector
switch and an ENTER push button to manually initialize the controller.
You can find the operation description of these facilities in this manual.
memory size. Available versions are designated PM511V08 or PM511V16.
Description
PM511V is a processor module for Advant Controller 450. It is designed to fit
The module has an interface to the S100 I/O extension bus which makes it possible
to connect it to the bus extension board DSBC 174 or DSBC 176 in a S100 I/O rack.
The PCMCIA slot accepts flash memory cards for system software.
