4.1

Overview

The internal architecture is based on several shared subsystem logics interconnected

through a multilayer interconnection matrix, shown in Figure 3.

The BUSMATRIX has 7 master inputs: two DMA inputs, and one input each for the CPU,

Reconfigurable Array Subsystem (RAS) block, Ethernet controller, USB controllers and C3.

There are 10 slave outputs connected to almost all the system blocks: low speed

subsystem, application subsystem, basic subsystem, high speed subsystem, RAS and

MPMC DDR memory controller ports.
