Figure 3: Input/output interface to the FIFOs. Depending on the bitwidth of the I/Os (three cases supported: , , and , ), and depending on the mode (rIrH, rIcH, cIrH, and cIcH), the I/O Interface to FIFOs varies. (a) Real input, real coefficients: the three supported cases of and are shown. (b) Real input, complex coefficients: the three supported cases of and are shown. (c) Complex input, real/complex coefficients: the three supported cases are shown.
