Connect to the VMEbus P2 connector. The motherboard is connected to the transition module adapter board and cable via P2. VMEchip2 ASIC provides VMEbus interface. VMEchip2 includes: The dual-scale timer is used for the programmable map decoder interface between the master and slave devices, as well as the VMEbus VMEbus to/from the local bus for non-DMA programming access to the InterfaceMCMC040 memory controller ASIC MEMC040 memory controller

ASIC Programmable interface board for odd-even protection of DRAM interlayer MCECC Memory controller Application-specific Integrated circuit MCECC Memory controller ASIC Provides programmable ECC interface for protecting DRAM interlayer board. This article introduces the main functional blocks of the MVME187 chapters, including: Front panel switch and LED indicator data bus structure The local data bus on the VME187 is a 32-bit synchronous bus based on the MC68040 bus, supporting burst transmission and snooping.

Local bus arbitration Various local bus master and slave devices use the local bus to communicate local bus by priority type arbitrators and the number of local bus master nodes with highest to lowest priority are: 1.82596CA LAN (Max) 2.CD2401 serial (via PCCCip2) 3.53C710 SCSI.VMEbus.MPU (min) In general, any host can access any slave; However, not all combinations are connected by "common sense testing" by referring to a single board programmer's reference guide and a user's guide for each device to determine its port size and data bus. The access device M88000 MPUMVME187 is based on the M88000 series and uses one MC88100 MPU and two MC88200 or MC88204 CMMU. One CMMU is used for data cache and the other for instruction cache.
