METHOD AND APPARATUS FOR DATA ACCESS IN A HETEROGENEOUS PROCESSING SYSTEM WITH MULTIPLE PROCESSORS USING MEMORY EXTENSION OPERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18099021 titled 'METHOD AND APPARATUS FOR DATA ACCESS IN A HETEROGENEOUS PROCESSING SYSTEM WITH MULTIPLE PROCESSORS USING MEMORY EXTENSION OPERATION
Simplified Explanation:
This patent application describes a system and method that includes a host processor, a first processor connected to a first memory, a second processor connected to a second memory, and switch and bus circuitry that links them all. The host processor maps virtual addresses of the second memory to physical addresses of the switch and bus circuitry and configures the first processor to directly access the second memory using these mapped physical addresses for memory extension operations. The first processor can be a reconfigurable processor, a reconfigurable dataflow unit, or a compute engine, and it can read or write data directly to the second memory while running an application.

Original Abstract Submitted
A heterogeneous processing system and method including a host processor, a first processor coupled to a first memory, a second processor coupled to a second memory, and switch and bus circuitry that communicatively couples the host processor, the first processor, and the second processor. The host processor is programmed to map virtual addresses of the second memory to physical addresses of the switch and bus circuitry and to configure the first processor to directly access the second memory using the mapped physical addresses according to memory extension operation. The first processor may be a reconfigurable processor, a reconfigurable dataflow unit, or a compute engine. The first processor may directly read data from or directly write data to the second memory while executing an application. The method may include configuring the first processor to directly access the second memory while executing an application for reading or writing data.
