The channel main features are the following:

●

Decoding of the instructions received from the dispatcher sub-system.

●

DMA engine with support of scatter and gather operations.

●

Internal input / output data-flows buffering by the means of FIFO in order to

accommodate for the system bus latency.

●

I/O multiplexing, so that data can be directly received from/sent to other channels

without going through memory.

●

Support for multiple algorithms in the Core block. The Core block implementation is

application specific.

28.3.5

CCM (Coupling/Chaining module)

This block implements a cross-bar allowing direct connection of channels Input/Outputs

between them. Typical use cases of the CCM are for:

●

Sending the output data generated by a channel to the input of another channel, also

known as “chaining”.

●

Sending the input data received by a channel from the system bus to the input of

another channel, also known as “coupling”.
