Introduction

This chapter describes the MVME240x VME processor module on a block
diagram level. The General Description provides an overview of the
MVME240x, followed by a detailed description of several blocks of
circuitry. Figure 3-1 shows a block diagram of the overall board
architecture.
Detailed descriptions of other MVME240x blocks, including
programmable registers in the ASICs and peripheral chips, can be found in
the MVME2400-Series VME Processor Module Programmer's Reference
Guide (part number V2400A/PG). Refer to it for a functional description
of the MVME240x in greater depth.
