Abstract-We evaluate the validity of the fundamental assumption behind application-specific programmable processors: that applications differ from each other in key parameters which are exploitable, such as the available instruction-level parallelism (ILP), demand on various hardware resources, and the desired mix of function units. Following the tradition of the CAD community, we develop an accurate chip area estimate and a set of aggressive hardware optimization algorithms. We follow the tradition of the architecture community by using comprehensive real-life benchmarks and production quality tools. This combination enables us to build a unique framework for system-level synthesis and to gain valuable insights about design and use of application-specific programmable processors for modern applications. We explore the application-specific programmable processor (ASSP) design space to understand the relationship between performance and area. The architecture model we used is the Hewlett Packard PA-RISC [1] with single level caches. The system, including all memory and bus latencies, is simulated and no other specialized ALU or memory structures are being used. The experimental results reveal a number of important characteristics of the ASSP design space. For example, we found that in most cases a single programmable architecture performs similarly to a set of architectures that are tuned to individual application. A notable exception is highly cost sensitive designs, which we observe need a small number of specialized architectures that require smaller areas. Also, it is clear that there is enough parallelism in the typical media and communication applications to justify use of high number of function units. We found that the framework introduced in this paper can be very valuable in making early design decisions such as area and architectural configuration tradeoff, cache and issue width tradeoff under area constraint, and the number of branch units and issue width.Index Terms-Application-specific programmable processor, instruction level parallelism, mediabench, mediaprocessor, system-level synthesis.

“…When considering compilers for application-specific architectures (e.g., DSPs), the compiler back-end is often more complex due to irregular structures such as inhomogeneous register sets and connections. As a result, instruction selection, register allocation, and scheduling are intertwined problems that are much harder to solve [Goossens et al 1997].…”

This tutorial surveys design methods for energy-efficient system-level design. We consider electronic systems consisting of a hardware platform and software layers. We consider the three major constituents of hardware that consume energy, namely computation, communication, and storage units, and we review methods for reducing their energy consumption. We also study models for analyzing the energy cost of software, and methods for energy-efficient software design and compilation.This survey is organized around three main phases of a system design: conceptualization and modeling, design and implementation, and runtime management. For each phase, we review recent techniques for energy-efficient design of both hardware and software.

In this paper we report a framework that makes it possible for a designer to rapidly explore the application-specific programmable processor design space under area constraints. The framework uses a production-quality compiler and simulation tools to synthesize a high performance machine for an application. Using the framework we evaluate the validity of the fundamental assumption behind the development of application-specific programmable processors. Application-specific processors are based on the idea that applications differ from each other in key architectural parameters, such as the available instruction-level parallelism, demand on various hardware components (e.g. cache memory units, register files) and the need for different number of functional units. We found that the framework introduced in this paper can be valuable in making early design decisions such as area and architectural trade-off, cache and instruction issue width trade-off under area constraint, and the number of branch units and issue width.
