System Configuration
5.1
This chapter describes several functions that control the local access windows, system configuration,
protection, and general utilities. These functions are discussed in the following sections:
5.2
The device provides a flexible local memory map. The local memory map refers to the 32-bit address space
seen by the processor as it accesses memory and I/O space. Internal DMA engines also see this same local
memory map. All memory accessed by the DDR SDRAM and local bus memory controllers exists in this
memory map, as do all memory-mapped configuration, control, and status registers.
The local memory map is defined by a set of nine local access windows. Each of these windows maps a
region of memory to a particular target interface, such as the DDR SDRAM controller or the PCI
controller. The DSP subsystem is not operational in the MSC7104. Note that the local access windows do
not perform any address translation. The size of each window can be configured from 4 Kbytes to
2 Gbytes. Each local access window is assigned to a specific target interface as specified in
