1.3 Architectural Overview
The MPC180 has a slave interface to the MPC8xx system bus and MPC8260 local bus and
maps into the host processor’s memory space. Each encryption algorithm is mapped to a
unique address space. To perform encryption operations, the host reads and writes to the
MPC180 to setup the execution unit and, then, transfers data to the execution unit directly
or through the external bus interface.
In FIFO mode, the MPC180 accepts data into the 4-Kbit input buffer and returns burst data
through the output buffer. In this way, the host can automatically transfer bulk data
through a given EU. This minimizes host management overhead and increases overall
system throughput. Once the host configures the external bus interface (EBI), it receives
an interrupt only after all data has been transferred or processed by the MPC180.
