I. Definition of Heterogeneous Chips
Heterogeneous chips, as the name suggests, refer to a single chip integrating multiple different types of processor cores. These cores can have different instruction set architectures (ISAs), different microarchitectures, different manufacturing processes, or different packaging technologies. This design approach enables heterogeneous chips to handle multiple types of tasks simultaneously, thereby improving overall computing efficiency.
II. Characteristics of Heterogeneous Chips
High integration: Heterogeneous chips integrate multiple types of processor cores on the same chip, enabling the sharing and optimization of hardware resources, thereby improving the overall performance of the system.
Flexibility: By integrating multiple types of processor cores, heterogeneous chips can adapt to different types of task requirements and flexibly schedule and allocate tasks.
High energy efficiency: Heterogeneous chips can select the most suitable processor core for processing according to different task requirements, thereby maximizing energy efficiency.
Scalability: The heterogeneous chip design allows it to be expanded as needed, increasing or decreasing the number and type of processor cores to adapt to different scenarios.
III. Applications of Heterogeneous Chips
