Embodiment Construction

[0022] Hereinafter, embodiments of the inventive concept are described in detail with reference to the accompanying drawings.

[0023] figure 1 is a block diagram illustrating computing system 10 according to an embodiment.

[0024] refer to figure 1 , computing system 10 may be variously referred to as a data processing system or a memory system, and computing system 10 may include one or more devices for requesting data access to memory device 13 . To the extent that memory device 13 operates as a host, the device for requesting access to memory device 13 may be referred to as a host device. According to an embodiment, computing system 10 is shown as including host 11 and accelerator 12 and memory device 13 , although accelerator 12 may also be referred to as a host device in computing system 10 .

[0025] The host 11 may include a device corresponding to a central processing unit (CPU) or a device including a CPU, and further, the host 11 may include a memory controller ...

Abstract

An accelerator, a computing system including the accelerator, and a method of operating the accelerator are provided. The accelerator includes a signal control / monitoring circuit configured to: detect entry into and exit from a self-refresh mode of a memory device based on monitoring a signal provided from a host; accelerator logic configured to: generate a first command / address signal and a first piece of data; and a selector configured to output a first command / address signal and a first piece of data to the memory device based on detection of entry into the self-refresh mode, and output a second command / address signal and a second piece of data provided from a host to the memory device based on detection of exit from the self-refresh mode.

Description

[0001] This application is based on and claims priority to Korean Patent Application No. 10-2021-0001476 filed in the Korean Intellectual Property Office on January 6, 2021, the disclosure of which is incorporated herein by reference in its entirety. technical field [0002] The inventive concept relates to accelerators, and more particularly, to accelerators controlling memory devices, computing systems including accelerators, and methods of operating the accelerators. Background technique [0003] A system (eg, a computing system) for performing data processing may include a host, including a central processing unit (CPU), and a memory device in which data is accessed by the host. The amount of data that needs to be processed by computing systems is increasing substantially, and as a method for increasing the processing speed, it has been proposed to reduce the processing of the CPU by offloading some operations from the CPU to other processors (eg, accelerators, etc.) loa...
