Xilinx Blocks

saturated as needed. A positive value is implemented as an unsigned number, a negative value as signed.

∙Number of Bits in Constant: specifies the bit location of the binary point of the constant, where bit zero is the least significant bit.

∙Multiplier Type: specifies the implementation to be parallel or sequential.

∙Memory Type: specifies whether to use distributed RAM or block RAM.

∙Require Maximum Pipelining: when checked, directs System Generator to pipeline the LogiCORE implementation to the fullest extent possible.

∙Hardware Over-Sampling Rate: specifies the number of hardware cycles per input sample; does not affect behavior in simulation, only the hardware implementation.

∙Use Placement Information for Core: allows specification of placement layout shape that will be used when implementing the core in hardware

∙Placement Style: specifies the layout shape in which the multiplier core will be placed in hardware. The Rectangular option will generate a rectangular placed core with loosely placed LUTs. Triangular packing will create a more compact shape, with denser placement of LUTs.

Other parameters used by this block are explained in the Common Parameters section of the previous chapter.

Xilinx LogiCORE

The block always uses the Xilinx LogiCORE Multiply Generator V4.0.
