linuswck	bd27e93a73	gateware: Revert IIR Coeff Width to 18bit ... - Revert commit 25dd0db. Related Issue: #40. - Fail to meet timing for IIR Filter's Multiply and Add operation as multiplication operation cannot be fitted inside a single DSP Slice (25b x 18b). Thus, multiple DSPs are needed for multiplication. This causes timing violation at 100MHz and 125MHz sys frequency.	2025-01-13 11:16:35 +08:00
