Figure 4-1) or any system using PCI. The ability of the MPC184 to be a master on the 8xx bus allows the
co-processor to offload the data movement bottleneck normally associated with slave devices. The external
processor accesses the MPC184 through its device drivers using system memory for data storage. The
MPC184 resides in the memory map of the processor, therefore when an application requires cryptographic
functions, it simply creates descriptors for the MPC184 which define the cryptographic function to be
performed and the location of the data. The MPC184’s mastering capability permits the host processor to
set up a crypto-channel with a few short register writes, leaving the MPC184 to perform reads and writes
on system memory to complete the required task.
