CHIPSET SUPPORT FOR NON-UNIFORM MEMORY ACCESS AMONG HETEROGENEOUS PROCESSING UNITS, CAPABLE OF ENABLING A PLURALITY OF HETEROGENEOUS PROCESSING UNITS TO ACCESS PHYSICAL MEMORY RELATED TO DIFFERENT PROCESSING UNITS IN A SAME SYSTEM

摘要

PURPOSE: A chipset support for non-uniform memory access among heterogeneous processing units is provided to enable heterogeneous processors to access to a random physical memory in a computer system without processors, operating systems, or memory controllers in a multiprocessor system.;CONSTITUTION: The first processor generates the first address map(302). The first address map comprises hardware devices(502-1~502-N), NUMA(Non-Uniform Memory Access) devices(504A), and apertures about a physical memory(106A). The second processor generates the second address map(304). The second address map comprises the hardware devices, NUMA devices(504B), and MMIO apertures about a physical memory(106B). Each address map comprises MMIO apertures about the hardware devices.;COPYRIGHT KIPO 2010
