Web5.1 Unrolling loops. According to Intel: The OpenCL kernel performs one loop iteration of each work-item per clock cycle. With sufficient hardware resources, you can increase kernel performance by unrolling the loop, which decreases the number of iterations that the kernel executes. To unroll a loop, add a #pragma unroll directive to the main loop. WebOpenCL Kernel Design Best Practices. With the Intel® FPGA SDK for OpenCL™ Offline Compiler technology, you do not need to change your kernel to fit it optimally into a fixed hardware architecture. Instead, the offline compiler customizes the hardware architecture automatically to accommodate your kernel requirements.
