126.96.36.199. Integration of an RTL Module into the Intel FPGA SDK for OpenCL Pipeline
The depicted RTL module has a balanced latency where the threads of the RTL module match the number of pipeline stages. A balanced latency allows the threads of the RTL module to execute without stalling the SDK's pipeline.
Setting the latency of the RTL module in the RTL specification file allows the offline compiler to balance the pipeline latency. RTL supports Avalon® streaming interfaces; therefore, the latency of the RTL module can be variable (that is, not fixed). However, the variability in the latency should be small in order to maximize performance. In addition, specify the latency in the OpenCL library object manifest file so that the RTL module experiences a good approximation of the actual latency in steady state.
