Detailed Description

Top feature-extracting algorithm module.

The output TOBS are sent in 5 clock cycles. Only eFEX handlig edge region really need to send out 5 TOBs per BC, most of the mouldes just need to send 4 TOBs. This is handled by the input position register. If bit 1 is '1', then theeFEX is an edge module, in this case bit 0 specifies whether the efex is at the left edge (low eta) bit 0 = '0' or at right edge (high eta) bit 0 = '1'. Bit 0 is otherwise ignored.
