Introduction
This chapter describes the MVME167P Single-Board Computer on a
block diagram level. The Summary of Features provides an overview of
the MVME167P, followed by a detailed description of several blocks of
circuitry.
shows a block diagram of the overall
board architecture.
Detailed descriptions of other MVME167P blocks, including
programmable registers in the ASICs and peripheral chips, can be found in
