Introduction
This chapter describes the MVME177P Single-Board Computer on a
block diagram level. The Summary of Features provides an overview of
the MVME177P, followed by a detailed description of several blocks of
circuitry. Figure 4-1 shows a block diagram of the overall board
architecture.
Detailed descriptions of other MVME177P blocks, including
programmable registers in the ASICs and peripheral chips, can be found in
the Programmer’s Reference Guide (part number V1x7PA/PG). Refer to
that manual for a functional description of the MVME177P in greater
depth.
