3.6. Load-Store Units
The Intel® FPGA SDK for OpenCL™ Offline Compiler generates a number of different types of load-store units (LSUs). For some types of LSU, the compiler might modify the LSU behavior and properties depending on the memory access pattern and other memory attributes.
Tip: For Intel® oneAPI DPC++/C++ Compiler-specific details, refer to Load-Store Units section in the Intel® oneAPI DPC++ FPGA Optimization Guide.
