Abstract

A heterogeneous computing system described herein has an energy-efficient architecture that exploits producer-consumer locality, task parallelism and data parallelism. The heterogeneous computing system includes a task frontend that dispatches tasks and updated tasks from queues for execution based on properties associated with the queues, and execution units that include a first subset acting as producers to execute the tasks and generate the updated tasks, and a second subset acting as consumers to execute the updated tasks. The execution units includes one or more control processors to perform control operations, vector processors to perform vector operations, and accelerators to perform multimedia signal processing operations. The heterogeneous computing system also includes a memory backend containing the queues to store the tasks and the updated tasks for execution by the execution units.

Description

technical field [0001] The present invention relates to heterogeneous computing, and more specifically, to an energy-efficient heterogeneous computing architecture. Background technique [0002] According to Dennard Scaling, voltage and current should be proportional to the linear size of the transistor, and power dissipation (ie, the product of voltage and current) should be proportional to the area of ​​the transistor. As the size of transistors continues to shrink, the number of transistors that can fit into the same area on a chip has grown exponentially. Therefore, previously predicted computing performance per watt (watt) can also show exponential growth. However, over the past decade, Dennard's scaling law appears to have broken down. Although the size of transistors has continued to shrink, computing performance per watt has not increased at the same rate. Dennard's scaling law fails for several reasons. One reason for this is that at small sizes, current leakage...
