Back-end compiler implementation method and device based on array analysis primitive structure

Abstract

The invention discloses a method and a device for realizing a back-end compiler based on an array type analysis primitive structure, which can meet the requirement of compiling a protocol analysis logic defined by software based on programmable target hardware of the array type analysis primitive structure. A protocol analysis processing logic described by software is translated and explained to generate an analysis operation instruction which can be identified by a matrix programmable analysis resource in target hardware, and the operation instruction forms a mapping relationship with a configurable analysis element array in the target hardware in the form of an analysis element parameter array; through an analysis primitive parameter array controller, effective analysis primitive parameters in an analysis primitive parameter array are configured into corresponding programmable analysis primitives on hardware, programming of programmable analysis primitive resources of target hardware is completed, and therefore the purpose that protocol-independent data analysis is achieved through software programming hardware is achieved.

Description

technical field [0001] The invention relates to the technical field of protocol-independent programmable analysis, compiler and intelligent network card, in particular to a method and device for implementing a back-end compiler based on an array analysis primitive structure. Background technique [0002] As a high-level programming language for data packet processing, P4 realizes protocol-independent and target-device-independent programming requirements, but this independence is limited to providing supporting intermediate representation (IR, Intermediate Representation). If users want to design a protocol Regardless of the hardware programmable parser and programming through software, it is necessary to design a back-end compiler to configure your own programmable hardware. There is currently no unified standard in the industry for the implementation of the back-end compiler, and The ability adaptation process between the compiler and the target hardware is cumbersome. In ...

[0002] As a high-level programming language for data packet processing, P4 realizes programming requirements that are protocol-independent and target-device-independent, but this independency is limited to the supporting Intermediate Representation (IR, Intermediate Representation), if the user wants to design a protocol-independent hardware programmable parser and program it through software, he needs to design a back-end compiler to configure his own programmable hardware, about back-end compilation At present, there is no unified standard in the industry, and the ability adaptation process between the compiler and the target hardware is cumbersome. In addition, there are many specifications of the parser hardware, and the compiler can adapt flexibly to parsers of different specifications. Performance and operability still need to be improved
