troller 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 processor. 

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 P

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.
