Apr 3, 2024 · "Many FPGA boards have specific multiply-accumulate hardware accelerators, called DSP slices that speed up the execution of signal processing functions. DSP slices vary in size depending on the vendor."

Feb 23, 2015 · I threw a 23x32 bit multiplier (output was [54:0]) into my test zedboard design and it needed 2 DSP slices (out of 220). I optimized the multiplier for speed (versus area) and used 1 pipeline stage. Depending on your settings for the multiplier IP, it will utilize different resources.

May 29, 2012 · FPGA’s have DSP slices to implement signal processing functions. The DSP operation most commonly used is Multiply-Accumulate or MAC operation. A MAC block is also used as a building block for more complex DSP applications like filtering. FPGA DSP slice essentially implements a MAC operation.

The AMD DSP slice and its parallelism is key to the achievable DSP performance in the latest generation of AMD FPGAs. DSP Slice Architecture. The DSP58 in Versal devices slice is the 6th generation of DSP slices in AMD architectures.

To gain the hardware acceleration benefits of DSP slices, it is common in FPGA design to map multiply and accumulate operations in the algorithm onto these slices. In this example, optimize data types for 3 DSP families of Xilinx® boards, as well as for a generic 18x18 bit input.

Apr 5, 2024 · Yes, you can use DSP slices in filters. You can use custom designs. You can use DSP slices anywhere in the FPGA fabric. Can you beat the performance of the FIR Compiler IP? I've never been able to do it. If you have a few weeks to devote to this, you might save a DSP slice or a couple 10's of picoseconds of clock period, but it isn't easy.

MACs per dollar and lower power for DSP applications. The Virtex-4 family contains a new element called the DSP48 slice that integrates a high-performance arithmetic and accumulation unit along with a multiplier. The DSP48 slice comprises four main sections: I/O registers. 18 x 18 signed multiplier. Three input adder/subtractor blocks.

It built upon prior architecture's DSP slices by adding additional capabilities over time. The various DSP slice user guides, (listed above), contain cumulative and supplemental material and references that can only be found in the previous versions of …

Apr 3, 2024 · Working with DSP slices in Xilinx FPGAs is similar to using Block RAM. You set up them in Vivado, setting parameters such as operating mode and precision, and then use them in your HDL code. DSP slices are ideal for high-speed mathematical calculations.

The DSP slice in the UltraScale architecture is defined using the DSP48E2 primitive and the slice is referred to as either DSP or DSP48E2 in the Xilinx tools.
