MC68030 MPU
The MC68030 is the main processor of the MVME147. The MC68030
has onchip instruction and data caches. The MVME147 prevents the
MC68030 from caching accesses to any other device than local
DRAM by activating the cache inhibit in pin (CIIN*) during the
accesses. Refer to the MC68030 Enhanced 32-Bit Microprocessor
User's Manual.
The MC68030 includes a software reset instruction; however, the
MVME147 does not support this instruction.
MC68882 FPC
The MC68882 Floating-Point Coprocessor (FPC) is connected to the
MC68030 as a 32-bit port. It runs at the same frequency as the
MC68030. Refer to the MC68881/MC68882 Floating-Point
Coprocessor User's Manual for a detailed description of its operation.
VMEchip
The VMEchip is an Application Specific IC (ASIC) device designed
to reduce the real estate required to interface with the VMEbus. It
provides the following:
? VMEbus system controller functions
? VMEbus interrupt handler
? VMEbus and local time-out functions
? MC68030 to VMEbus interface
? VMEbus control signal drivers and receivers. Functional Description
