LatticeECP-DSP sysDSP Usage Guide
MULT Module
The MULT Module configures elements to be packed into the sysDSP primitives. The Basic mode screen illustrated
in Figure 15-2 consists of one clock (optional), one clock enable and one reset tied to all registers. Using the multi-
plier you can span multiple sysDSP Blocks. The SRI and SRO ports can only be enabled if inputs are less than 18
bits. The Advanced mode screen, illustrated in Figure 15-3, allows finer control over the register. In the Advanced
mode you can control each register with independent clocks, clock enables and resets.
