Modern signal processing systems require more and more processing capacity as times goes on. Previously, large increases in speed and power efficiency have come from process technology improvements. However, lately the gain from process improvements have been greatly reduced. Currently, the way forward for high-performance systems is to use specialized hardware and/or parallel designs. Application Specific Integrated Circuits (ASICs) have long been used to accelerate the processing of tasks that are too computationally heavy for more general processors. The problem with ASICs is that they are costly to develop and verify, and the product life time can be limited with newer standards. Since they are very specific the applicable domain is very narrow. More general processors are more flexible and can easily adapt to perform the functions of ASIC based designs. However, the generality comes with a performance cost that renders general designs unusable for some tasks. The question then becomes, how general can a processor be while still being power efficient and fast enough for some particular domain? Application Specific Instruction set Processors (ASIPs) are processors that target a specific application domain, and can offer enough performance with power efficiency and silicon cost that is comparable to ASICs. The flexibility allows for the same hardware design to be used over several system designs, and also for multiple functions in the same system, if some functions are not used simultaneously. One problem with ASIPs is that they are more difficult to program than a general purpose processor, given that we want efficient software. Utilizing all of the features that give an ASIP its performance advantage can be difficult at times, and new tools and methods for programming them are needed. This thesis will present ePUMA (embedded Parallel DSP platform with Unique Memory Access), an ASIP architecture that targets algorithms with predictable data access. These kinds of algorithms are very common in e.g. baseband processing or multimedia applications. The primary focus will be on the specific features of ePUMA that are utilized to achieve high performance, and how it is possible to automatically utilize them using tools. The most significant features include data permutation for conflict-free data access, and utilization of address generation features for overhead free code execution. This sometimes requires specific information; for example the exact sequences of addresses in memory that are accessed, or that some operations may be performed in parallel. This is not always available when writing code using the traditional way with traditional languages, e.g. C, as extracting this information is still a very active research topic. In the near future at least, the way that software is written needs to change to exploit all hardware features, but in many cases in a positive way. Often the problem with current methods is that code is overly specific, and that a more general abstractions are actually easier to generate code from.

Programmable digital signal processors (DSPs) are microprocessors with specialized architectural features for the efficient execution of digital signal processing algorithms at relatively low cost. These features also make DSPs difficult targets for high-level language (HLL) compilers, and require that assembly language programming be used to fully exploit their capabilities. As applications become larger and more complex, and as design cycles are required to be shorter, it is important to move towards using more HLL programming. To achieve this, more compiler-friendly DSP architectures and better DSP compiler technology are required. As DSP cores become more pervasive in embedded system-on-a-chip designs, a need is also emerging for application-specific DSP cores that can be customized to the functional, performance, and cost requirements of a target application, or group of applications. This dissertation examines the use of VLIW architectures to achieve a suitable compiler target while being able to express the forms of parallelism found in most DSP applications. Performance improvements by factors of 1.8-2.8 are shown to be achievable simply by using a VLIW architecture compared to more traditional architectures. A method for reducing the instruction bandwidth and storage requirements of VLIW architectures is also proposed, and its impact on performance and cost is examined. To handle some of the DSP-specific architectural features, an optimizing C compiler is developed. In particular, two algorithms that enable the compiler to allocate data automatically across dual data-memory banks are developed, and their impact on cost and performance are examined. Finally, a set of tools that enable a designer to customize the architecture and its instruction set to the requirements of a target application is also presented. This includes an area-estimation model and an instruction-set simulator for measuring cost and execution performance.
