The CASE tool for programming of the multi-core System-on-a-Chip with the data flow computation control

Abstract

The paper describes Computer Aided Software Engineering (CASE) tool, that supports programming of the experimental multi-core tile based System-on-a-Chip (SoC). SoC comprises cores, which are based on the data flow computation control principle. Proposed CASE tool allows creation of the program code in graphical form using Data Flow Graph (DFG) or in text representation using assembly language or machine code. Automatic transformations between those representations are supported. CASE tool brings sequential, mask based and global multi-mapping of the program code, which was introduced in our previous research. Another output lies in introduction of altered assembly language and machine code that allow multi-mapping of the program code on the instructions level. The aim of the solution lies in optimization of the program load phase in multi-core microprocessors that comprise tens or potentially hundreds of cores.
