8.2.2.1. Heterogeneous Memory Buffers
If your FPGA board offers heterogeneous global memory types, keep in mind that they handle different memory accesses with varying efficiencies.
For example:
- Use DDR SDRAM for long sequential accesses.
- Use QDR SDRAM for random accesses.
- Use on-chip RAM for random low latency accesses.
For more information about how to allocate buffers in global memory and how to modify your host application to use heterogeneous buffers, refer to the Specifying Buffer Location in Global Memory and Allocating OpenCL Buffer for Manual Partitioning of Global Memory sections of the Intel® FPGA SDK for OpenCL™ Programming Guide.
