“…This has been quantified in a study by Paulin [55], who found that for a certain set of DSP applications, about 90% of DSP code lines are written in assembly, while the use of C only accounts for 10%.…”

The role of software is becoming increasingly important in the implementation of digital signal processing (DSP) applications. As this trend intensifies, and the complexity of applications escalates, we are seeing an increased need for automated tools to aid in the development of DSP software. This paper reviews the state-of-the-art in programming language and compiler technology for DSP software implementation. In particular, we review techniques for high-level block-diagram-based modeling of DSP applications; the translation of block-diagram specifications into efficient C programs using global target-independent optimization techniques; and the compilation of C programs into streamlined machine code for programmable DSP processors using architecture-specific and retargetable back-end optimizations. We also point out important directions for further investigation.

“…As a result, the code quality of high-level procedural language (such as C) compilers for PDSP's has been several hundreds of percent worse than manually written assembly language code [6], [55]. This situation has necessitated the widespread use of assembly-language coding, and tedious performance tuning, in DSP software development.…”

“…It comes with a development environment that integrates a compiler, linker, loader, debugger and diagnostics in a single package. With the Dynamic C environment, some of the engineering costs associated with tool development and support, which has been found to account for 15% of the effort in embedded systems development [11], can be minimized and factored away from our exercise.…”

“…Domain specific designs such as ASIPs, ASICs and tools such as SDLs, have forced embedded software to be re-engineered from scratch almost every time. It has been shown that software development for embedded applications and firmware account for up to 33% of the manpower allocation for many embedded systems projects [11].…”

Abstract-Architecture Description Languages (ADLs) are widely used to perform design space exploration for Application Specific Instruction Set Processors (ASIPs). While the design space exploration is well supported by numerous tools providing high flexibility and quality, the methodology of automated implementation is limited to simple transformations. Assuming fixed architectural templates, information given in the ADL is directly mapped to a hardware description on Register Transfer Level (RTL). Gate-Level synthesis tools are not able to perform potential optimizations, as the computational complexity grows exponential with the size of the architecture. Information such as exclusiveness, parallelism or boolean relations are spread over multiple modules and therefore hard to determine. In this paper, we present an ASIP synthesis approach from architecture description languages, based on an Intermediate Representation (IR). The IR is the key technology to provide new languageindependent high-level optimizations and to realize different hardware description language backends. The feasibility of our approach is proven in a case-study.
