This paper deals with retargetable compiler generation. After an introduction to applicationspecific instruction set processor design and a review of code generation in compiler backends, ISAC architecture description language is introduced. Automatic approach to instruction semantics extraction from ISAC models which result is usable for backend generation(More)
The embedded systems with application specific ins truction set processors, on which specific software runs, has become an inseparable part of ou r everyday life. Therefore, powerful tools for thei r development are necessary. Each tool is used in dif ferent phases of an embedded system design. One of the key phases is the testing of processor and soft ware(More)
Application-specific instruction set processors used in embedded systems are highly optimized for a given task. On this type of processors runs a specific application. Therefore, the designer should have a tool which helps him or her in the task of processor and application optimization. One of such tools is profiler. It can discover problematic parts, such(More)
Most of modern embedded systems for multimedia and network applications are based on parallel data stream processing. The data processing can be done using very long instruction word processors (VLIW), or using more than one high performance application-specific instruction set processor (ASIPs), or even by their combination on single chip. Design and(More)
We describe an automated way to generate data for a practical LLVM instruction selector based on machine-generated description of the target architecture at register transfer level. The generated instruction selector can handle arbitrarily complex machine instructions with no internal control flow, and can automatically find and take advantage of arithmetic(More)
