Abstract

The invention provides a memory coupling compiling method and system for a reconfigurable chip. The memory coupling compiling method comprises the following steps: acquiring the periodicity of a DFG data flow diagram; obtaining a linear conversion vector of the periodicity through the mapping time difference; and judging whether a linear array of the linear conversion vector can be obtained through a heuristic algorithm or not, obtaining a memory mapping result according to a judgment result or through the current DFG data flow diagram, and obtaining and adjusting the current DFG data flow diagram until the linear array is obtained. According to the method and the device, each node in the DFG data flow diagram is adjusted, so that the requirement of obtaining the linear array is met, the compiling time is greatly shortened, and the compiling experience of a user is very strong. The reconfigurable acceleration chip is high in practicability, can be used, and has extremely high reusability for programmable devices.

Description

technical field [0001] The invention relates to the development of a reconfigurable processor, and is applied to a compiler and compiling process of a reconfigurable compiler. The invention specifically relates to a memory coupling compiling method and system for a reconfigurable chip. Background technique [0002] In the compilation process of the compiler for the typical reconfigurable processor CGRA based on the LLVM compilation framework (Low Level Virtual Machine) compilation framework, its main goal is to make the user's application common through the front end of the LLVM compilation framework of the reconfigurable compiler After the lexical, grammatical and semantic analysis, the intermediate expression (IR, Intermediate Representation) is optimized and the appropriate data flow graph is extracted. After task division and storage allocation, operator scheduling and mapping work, etc., the application needs to be generated in The binary configuration information (Con...
