Security Engine (SEC) 3.0
10.4
The polychannel is the main control unit in the SEC. It implements four independent channels.
Each cryptographic task performed by the SEC is managed by a channel and makes use of one or more of
the SEC’s execution units (EUs). Control information and data pointers for a given task are stored in the
form of a descriptor (see
determines what EUs are used, how they are configured, where to fetch needed data, and where to store
the results.
The following subsections describe the operation (including descriptor processing, arbitration, and host
notification), registers, and interrupts of the polychannel.
10.4.1
10.4.1.1
To invoke a cryptographic task, the host constructs a descriptor, selects a channel, and writes a pointer to
the descriptor into the selected channel’s fetch FIFO. Each fetch FIFO can store up to 24 pointers.
