Xilinx Blocks

64.This corresponds to one CLB per output bit. If the table depth is greater than 64, a quarter wave is stored, and additional logic is used to generate the remaining portions of the wave. Storing only the quarter wave for the large tables reduces the area needed. Block memory stores a full wave for all table depths and widths that can be implemented in a single block memory. Otherwise, values are stored as a quarter wave. Latency for the distributed ROM implementation is determined by the input width, whether or not the block is pipelined, and the given latency value.

Threshold

The Xilinx Threshold block tests the sign of the input number. If the input number is negative, the output of the block is -1; otherwise, the output is 1. The output is a signed fixed point integer that is 2 bits long. The block has one input and one output.
