Architecture Design Method of Heterogeneous Multi-core SoC

Abstract

The heterogeneous multi-core SoC architecture design method provided by the present invention includes: obtaining the first call function set according to the running time and access times of the functions in the algorithm of the application field; and designing the simulation input stimulus by analyzing the calculation characteristics of the first call function set ; Determine the exploration space of the first SoC architecture according to the design requirements of the application field; trim the exploration space of the first SoC architecture to obtain the exploration space of the second SoC architecture; randomly select from the exploration space of the second SoC architecture Combining variables, simulating and synthesizing each group of SoC architectures to obtain running time, chip area, and power consumption; using machine learning algorithms to train variable combinations, running time, chip area, and power consumption to obtain regression models or classification models; using The above model explores the exploration space of the second SoC architecture and selects the SoC architecture satisfying multiple constraints from it. The invention can realize optimal heterogeneous multi-core SoC architecture design.

Description

technical field [0001] The invention relates to computer application technology, in particular to an architecture design method of a heterogeneous multi-core SoC. Background technique [0002] With the continuous development of chip manufacturing technology, the problem of energy consumption and heat dissipation makes all the units contained on the chip unable to work normally at the same time, that is, some circuits on the chip will become black silicon (dark silicon), wasting resources. In the past, chips that blindly pursued high frequency, high capacity, and isomorphic multi-core will encounter development bottlenecks; at the same time, the demand for chips with multiple functions, high efficiency, low power consumption, and easy portability in today's society is getting higher and higher, especially the current rapid development. Supercomputing fields, mobile communications and intelligent multimedia fields, etc. As a result, heterogeneous multi-core processor chips fo...
