WebCategory: 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.
