SYSTEM, DEVICE AND METHOD FOR ACCESSING DEVICE-ATTACHED MEMORY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18166244 titled 'SYSTEM, DEVICE AND METHOD FOR ACCESSING DEVICE-ATTACHED MEMORY

Simplified Explanation

The abstract describes a device that is connected to a host processor via a bus. The device includes an accelerator circuit and a controller. The accelerator circuit operates based on a message received from the host processor. The controller controls access to a memory connected to the device. When the accelerator circuit sends a read request, the controller sends a message to the host processor requesting resolution of coherence and prefetches data from the memory.

• The device is connected to a host processor via a bus.
• It includes an accelerator circuit and a controller.
• The accelerator circuit operates based on a message from the host processor.
• The controller controls access to a connected memory.
• When a read request is received from the accelerator circuit, the controller sends a message to the host processor requesting coherence resolution.
• The controller also prefetches data from the memory.

Potential Applications

• This technology can be used in devices that require high-speed data processing, such as graphics processing units (GPUs) or artificial intelligence accelerators.
• It can be applied in systems that require efficient memory access and data transfer, such as data centers or supercomputers.

Problems Solved

• The technology solves the problem of efficiently accessing and transferring data between a host processor and an accelerator circuit.
• It addresses the issue of coherence between the host processor and the accelerator circuit, ensuring that the most up-to-date data is used.

Benefits

• The device allows for faster data processing by offloading tasks to the accelerator circuit.
• It improves overall system performance by efficiently managing memory access and data transfer.
• The technology ensures coherence between the host processor and the accelerator circuit, preventing data inconsistencies.

Original Abstract Submitted

A device connected to a host processor via a bus includes: an accelerator circuit configured to operate based on a message received from the host processor; and a controller configured to control an access to a memory connected to the device, wherein the controller is further configured to, in response to a read request received from the accelerator circuit, provide a first message requesting resolution of coherence to the host processor and prefetch first data from the memory.
