  • 149-pin Ceramic PGA Package (15Y15 grid)

  • Optimized for Real-Time Response (Maximum 900 ns for 32-byte Interrupt Packet)

  • Processor Independent Interface to the PSB

  • Supports coexistence of dual port and message passing communication protocols

  • Dual Buffer Input and Output DMA capabilities

 

The 82389 Message Passing Coprocessor (MPC) is a highly integrated VLSI CMOS device that maximizes the performance of a Multibus II multiprocessor system.  The MPC implements the full message passing protocol as well as the functions (arbitration, transfer and exception cycle protocols) of the PSB bus interface control as defined in the IEEE/ANSI Standard 1296.  The 82389 MPC is designed to interface with the 32-, 16-, or 8-bit processor.  It provides support for message passing, interconnect space, memory, and I/O references on the PSB.  Additionally, the 82389 MPC component is designed to simplify implementation of dual port memory functions for those designs that will co-exist with the message passing communications protocol.
