Figure 19-1. Simplified Platform Block Diagram

In Figure 19-1, the platform bus is the AMBA AHB, the AXBS is the AHB crossbar switch (arbiter), and

the MCM is the Miscellaneous Control Module where error detection information is stored. Refer to the

appropriate chapter for a complete description. Contained in this document are descriptions of: interfaces

to the AHB, MCM and RAM array; the ECC (Error Correcting Code) algorithm and functionality; block

timing constraints; timing diagrams illustrating functionality and perfomance; and overall block

functionality descriptions. Shown in Figure 19-2 is a block diagram illustrating the 32 bit AHB to 17/18

bit PRAM address path and the 64/32 bit AHB to 78/39 bit PRAM data path through the module.
