Software and hardware cooperating design method for arithmetic acceleration

Abstract

The invention discloses a software and hardware collaborative design method of algorithm acceleration. The method has six steps of: step 1: static analysis of algorithm and software; step 2: using software analysis tools to carry out dynamic actual measurement analysis of the software so as to obtain a basic data chart of software operation; step 3: making overall structure and function design of a multi-core hardware system by combination of system requirements, the algorithm analysis and the software actual measurement analysis data; step 4: using appropriate modeling tools (RML) to describe the whole system; step 5: constructing a function process abstract chart GCG (including a function call chart of operation time parameters) on the base of the step 2 and discussing the distribution of the software in the multi-core system by using the chart GCG as the subject; and step 6: carrying out the software and hardware realization of a prototype system according to a proposal obtained from the step 5 and evaluating the realization results. The method has good compatibility, is applicable to the urgent demand for the design of a multi-core system on chip (SOC) and promotes the improvement of multi-core design tools. The method has very high utility value and promising application prospect.

Description

(1) Technical field [0001] The invention relates to a design method, in particular to an algorithm-accelerated software-hardware collaborative design method. It is a network security RSA algorithm based on hardware prototype evolution, and belongs to the technical fields of integrated circuit, system on chip (SOC), and embedded system design. (2) Background technology [0002] Software-hardware co-design is not only a design technique, but also a new design methodology. Its core problem is to coordinate software subsystems and hardware subsystems. [0003] The definition of software-hardware co-design has not yet been completely consistent, mainly in the following categories: [0004] David W. Franke (David W. Franke) and Martin K. Purvis (Martin K. Purvis) believe: "Software and hardware co-design is a kind of combination of software and hardware in the initial stage of the design process. A design method that is considered in combination to obtain design flexibility and ...

Problems solved by technology

[0009] Defects of the software-hardware collaborative design method based on intellectual property modules (IP): 1) Lost the fineness of high-level synthesis, and cannot adjust and optimize the specific functions of the selected intellectual property module (IP) according to the characteristics of the data flow graph; 2) Although in order to meet the needs of large-scale task flow graphs, the scale of functional units has been increased from simple operators to intellectual property modules (IP), but this mechanical increase still cannot achieve the true orientation of specific system constraints. Flexibly grasp the scale and performance of the hardware; 3) It is necessary to carefully adjust the interface timing between intellectual property modules (IP), which increases the design burden and makes the system not optimized enough

In the sense of software-hardware collaborative design, it means that the software-hardware collaborative design method based on intellectual property modules (IP) is a "semi-custom" design method, and it cannot flexibly adjust the proportional relationship between software and hardware according to system constraints.
