Intel: Are there any restrictions on the use of printf statements in OpenCL™ kernels?
Category: OpenCL™
Tools: Intel® FPGA SDK for OpenCL™
device:-
During kernel execution, printf data is stored in a global printf buffer that is automatically allocated by the Intel FPGA SDK for OpenCL™ Offline Compiler.
The size of this buffer is 64 KB, so the total size of the data arguments in the printf call should not exceed this size.
