WebThis improves the IP Core throughput. HLS has different pragmas to allocate resources for the executed operations. The low-resource FPGA device used has DSP cores that can perform multiplication and accumulation in one clock cycle. Applying the BIND_OP impl = DSP pragma forces DSP blocks to be used. WebThis pragma enables pipelining for a given loop in the code. Loop pipelining allows a new iteration of the loop to begin before the current one has finished, achieving higher …
