126.96.36.199. Adder Trees and Scalar Products
The gemm_flash design example is a generalized matrix multiplication design that uses the Scalar Product block to calculate an inner product. The adder tree and the Scalar Product block have similar parameters:
- Fused datapath. Enable this option to reduce logic utilization at the expense of IEEE compliance
- Rounding modes:
- Down (towards negative infinity)
- Up (towards positive infinity)
- Towards zero
When you turn on Fused datapath, you can select only the rounding modes Nearest and Towards zero. Logic utilization is highest when your design uses rounding mode Nearest.
