Register Frontends

The Register frontends are built as a register file using lowrisc’s reggen.py tool.

To configure a transfer, the corresponding registers can be filled with the transfer details, requesting the a next transfer ID once all registers are appropriately filled will launch the transfer. The transfer status can be queried using the transfer ID, as soon as the done_id is equal to or larger than the id received when launching the transfer the transfer is complete.

There are a variety of configurations, depending on the bitwidth and feature set required. Currently supported are:

• 32bit 3D register frontend

• 64bit 2D register frontend
