US Patent 8443147 Memory interleave for heterogeneous computing

A memory interleave system for providing memory interleave for a heterogeneous computing system is provided. The memory interleave system effectively interleaves memory that is accessed by heterogeneous compute elements in different ways, such as via cache-block accesses by certain compute elements and via non-cache-block accesses by certain other compute elements. The heterogeneous computing system may comprise one or more cache-block oriented compute elements and one or more non-cache-block oriented compute elements that share access to a common main memory. The cache-block oriented compute elements access the memory via cache-block accesses (e.g., 64 bytes, per access), while the non-cache-block oriented compute elements access memory via sub-cache-block accesses (e.g., 8 bytes, per access). A memory interleave system is provided to optimize the interleaving across the system's memory banks to minimize hot spots resulting from the cache-block oriented and non-cache-block oriented accesses of the heterogeneous computing system.
