WOODWARD 5501-340 Servo drive

The MVME188A family of RISC microcomputers offers a flexible new means of achieving next generation increases in computing power for technical and commercial computer system OEM applications. Specific applications encompass large multi-user compute servers, network/communications controllers, large file and database servers, as well as image processing, visualization, real-time simulation, and artificial intelligence. Up to 132 MIPS are provided by the MVME188A concept which combines in a single unit three standard single-wide, double-high VMEmodules: the system controller board, one or more memory boards, and the main logic board. The three boards are interconnected through a very high-speed local bus (also called the slave bus, or S bus). Because the S bus is a modified form of the M bus, descriptions of registers and other circuits sometimes describe it as the M bus

The system controller board contains

 a VMEbus A16 slave interface, ROM, static RAM, UARTs, timing elements, and local and global control/status registers. On the memory board, a 16MB DRAM (or 64MB DRAM or 32MB ECC DRAM) complement communicates with the CMMU devices on the mezzanine over the high speed S bus. Memory capacity can be increased to 64MB (or 256MB or 128MB) by adding one to three MVME288 series memory boards with 16MB DRAM (or 64MB DRAM or 32MB ECC DRAM) each. Up to four clusters of MC88100 RISC microprocessors closely coupled with MC88200 or MC88204 Cache/Memory Management Units (CMMUs) are contained on a HYPERmodule mezzanine module plugged into the main logic board (CPU board). The main logic board contains a full 32-bit VMEbus interface, as well as address decode logic and M bus (CMMU memory bus) interface logic.

System Controller Board Functional Description

 Located on the left of the MVME188A board set, the system controller board contains the VMEbus A16 slave interface, system controller functions, and other facilities including some commonly required by a microcomputer operating in a VMEbus environment. The system controller board complement includes: two serial ports, four programmable timers, four 32-pin JEDEC ROM sockets, SRAM and battery-backed SRAM, switches, and indicator LEDs. Also provided are 21 registers, not including the 8-register Global Control and Status Register (GCSR) set, or the registers in the RTC, DUART, and 00.
