This FPGA tutorial demonstrates applying the loop_coalesce attribute to a nested loop in a task kernel to reduce the area overhead. WebThe datapath of a loop within a single work-item kernel can contain multiple iterations in flight. This behavior is different from a loop within an NDRange kernel in that an NDRange kernel's loop contains multiple work-items (rather than loop iterations) in flight. In an optimally pipelined loop, a new loop iteration is launched every clock cycle. ina feet https://axisas.com

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.

WebIn the case, when a loop in a kernel is unavoidable, minimize the overhead by unrolling the loop either partially or completely in code, or using macros, and also minimize memory accesses within the loop. The following example demonstrates partial unrolling of a loop in the example OpenCL™ kernel.
