Figure 4-2 Integrator system memory map

Note

The Integrator system implements a distributed address decoding scheme in which each

core or logic module is responsible for decoding its own address space. It is important

when implementing a logic module design, to ensure that the module responds to all

memory accesses in the appropriate memory region (see the user guide for your

motherboard).

4.1.4 Address assignment of logic modules

The Integrator motherboards can have more than one logic module mounted on them.

The base address of each logic module depends on its position in the stack and defines

the value of bits [31:28] of the address for all devices on the logic module. Table 4-2 on
