PROTOTYPING THE TI TMS320C40 TO THE CYPRESS VIC068/VAC068 VME INTERFACE

The VIC068/VA068 is designed to interface with the Motorola 68000 microprocessor family, so interfacing it to the TMS320C40 digital signal processor (DSP) requires a logic simulation or configurable prototype. This document focuses on the details of the hardware design and the programmable logic source code interfacing the VIC068 to the TMS320C40 32-bit parallel DSP. It provides the details on the prototyping effort, so that others may examine this approach and minimize the design time in further efforts. This design is not optimized for speed or size. The appendix contains the assembler code software initialization for the TMS320C40. This document assumes the user is familiar with the TMS320C40 architecture, VMEbus, and its protocol(s).
