Abstract
An electronic device includes: a host processor configured to control an operation of the electronic device; accelerators of heterogeneous hardware types configured to exchange data with each other through direct communication; and a control unit configured to convert a command received from the host processor, based on a type of each of the accelerators and transfer a result of the converting to a corresponding accelerator among the accelerators.
Claims18
An electronic device, comprising:
- accelerators of heterogeneous hardware types, comprising different interfaces, configured to exchange data with each other through direct communication;
- and
- a controller, without interference by a host processor and a software stack, configured to:
- perform an interface translation on a command corresponding to an operation received from the host processor, based on a type of each of the accelerators and an interface difference between the accelerators;
- transfer a result of the interface translation on the command to an accelerator corresponding to the command among the accelerators;
- and
- the accelerator corresponding to the command executes the transferred result of the interface translation on the command,
- wherein the accelerators and the controller are distinguished from the host processor that controls the electronic device,
- wherein among the accelerators there is an accelerator with a first interface type and an accelerator with a second interface type that is different than the first interface type which directly communicate with each other without interference by the host processor and the software stack.

- and
- an interconnect switch, configured to manage the direct communication between the accelerators without interference by a host processor and a software stack;
- a controller configured to, without interference by the host processor and the software stack, convert a command corresponding to an operation received from the host processor based on a type of each of the accelerators and transfer a result of the conversion of the command to an accelerator corresponding to the command among the accelerators;
- the accelerator corresponding to the command executes the transferred result of the conversion of the command;
- wherein the accelerators and the interconnect switch are distinguished from the host processor that controls the electronic device, and
- wherein among the accelerators there is an accelerator with a first interface type and an accelerator with a second interface type that is different than the first interface type which directly communicate with each other without interference by the host processor and the software stack.
4 more elements
An electronic device, comprising:
- accelerators of heterogeneous hardware types with different interfaces configured to exchange data with each other through direct communication;
- and
- a controller, without interference by a host processor that controls the electronic device and without interference by a software stack, configured to:
- divide an operation into a data receiving operation, a data processing operation, and a data transferring operation;
- divide each of the data receiving operation, the data processing operation, and the data transferring operation into respective sub-operations;
- perform scheduling of each of the sub-operations of the data receiving operation, the sub-operations of the data processing operation, and the sub-operations of the data transferring operation for one or more of the accelerators based on a dependency between the sub-operations of the data receiving operation, the sub-operations of the data processing operation, and the sub-operations of the data transferring operation and characteristics of the sub-operations of the data receiving operation, the sub-operations of the data processing operation, and the sub-operations of the data transferring operation;
- and
- the one or more of the accelerators execute the sub-operations of the data receiving operation, the sub-operations of the data processing operation, and the sub-operations of the data transferring operation,
- wherein among the accelerators there is an accelerator with a first interface type and an accelerator with a second interface type that is different than the first interface type which directly communicate with each other without interference by the host processor and the software stack.
