Development of Digital's PCI Chip Sets and Evaluation Kit for the DECchip 21064 Microprocessor

The DECchip 21071 and the DECchip 21072 chip sets were designed to provide simple, competitive devices for building cost-focused or high-performance PCI-based sys- tems using the DECchip 21064 family of Alpha AXP microprocessors. The chip sets include data slices, a bridge between the DECchip 21064 microprocessor and the PCI local bus, and a secondary cache and memory controller. The EB64+ evaluation kit, a companion product, contains an example PC mother board that was built using the DECchip 21064 microprocessor, the DECchip 21072 chip set, and other off-the-shelf PC components. The EB64+ kit provides hooks for system designers to evaluate cost/performance trade-offs. Either chip set, used with the EB64+ evalu- ation kit, enables system designers to develop Alpha AXP PCs with minimal design and engineering effort.
