Framework for dram to physical address conversion

One or more physically manufactured computer-readable storage media, encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:

• receiving a system physical address from a memory management unit (MMU);
• determining, based on the system physical address, a cluster of L3 cache nodes that are connected to a set of memory controller nodes;
• determining, based on the system physical address, an L3 cache node tied to a component hub in a SoC mesh;
• determining a memory controller node in the SoC mesh that maps to the system physical address;
• generating a deinterleaved address by relocating low DRAM space of the system physical address and removing the cache cluster bits from the system physical address;
• mapping the deinterleaved physical address to a DRAM address by assigning bits to DRAM address components;
• and
• storing the bit assignments of the DRAM address components.

A system comprising:

• memory;
• one or more processing units;
• and
• a forward and reverse mapping system stored in the memory and executable by the one or more processor units, the cache coherence system encoding computer-executable instructions on the memory for executing on the one or more processor units a computer process, the computer process comprising:
• determining, based on a system physical address, a cluster of L3 cache nodes that map to a set of memory controller nodes;
• determining, based on the system physical address, an L3 cache node tied to a component hub in a SoC mesh;
• determining a memory controller node in the SoC mesh that maps to the system physical address;
• generating a deinterleaved address by relocating low DRAM space of the system physical address and removing the cache cluster bits from the system physical address;
• mapping the deinterleaved physical address to a DRAM address by assigning bits to DRAM address components;
• and
• storing the bit assignments of the DRAM address components.
