(4) Nested Loop Intel® FPGA SDK for OpenCL的离线编译器由于循环迭代无法infer pipeline的执行,会导致外循环的迭代相对于随后的内循环可能是乱序的,因为对于不同的外循环迭代,内循环的迭代次数可能会有所不同。要解决无序的外循环迭代问题,需要设计上下限在外循环迭代之间不变的内循环。 通过使用loop_coalesce...
I've been trying to run vector_add opencl exmaple to run on cyclone 5 SOC. It is perfectly working if I use default linux image given in Intel FPGA SDK for OpenCL. As default linux is compiled using gcc-linaro 4.7. I have compiled openCL example with gcc-linaro 4.7 ...
I get the error CL_INVALID_PLATFORM if I try to run the official samples with the CPU (both my iGPU and discrete GPU work fine with those). The CPU in question is i5 7300HQ. It should support OpenCL 2.1 even, so I assume that it has something to do with the OpenCL runtime....
