Reducing device energy has become one of the most important challenges to embedded systems designers. Processors with dynamic voltage scaling permit trading performance for reduced energy consumption as a program executes. In this paper, we first ...

Due to ever increasing number of transistors and decreasing threshold voltages, leakage energy consumption is expected to play a decisive role in the next generation circuits. We believe that software support is a must to exploit available leakage ...

In the embedded domain, memory usage and energy consumption are critical constraints. Dual width instruction set embedded processors such as the ARM provide a 16-bit instruction set in addition to the 32-bit instruction set to address these concerns. ...

More and more devices contain computers with limited amounts of memory. As a result, code compaction techniques are gaining popularity, especially when they also improve performance and power consumption, or at least not degrade it. This paper ...

Modern embedded processors with dedicated address generation unit support memory access with indirect addressing mode with auto-increment and decrement. The auto-increment/decrement mode saves address arithmetic instructions.Liao et al [2][3] ...

The availability of high-level design entry tooling is crucial for the viability of any reconfigurable SoC architecture. This paper presents a graph covering algorithm. The graph covering is done in two steps: template generation and template selection. ...

With the increasing demand for flexible yet highly efficient architecture platforms for media applications, there is a growing interest in the Coarse-grained Reconfigurable Architectures (CRAs). While many CRAs have demonstrated impressive performance ...

As embedded DSP applications become more complex, it is increasingly important to provide high-level stream abstractions that can be compiled without sacrificing efficiency. In this paper, we describe scheduler support for StreamIt, a high-level ...

The advent of Java and similar languages on the real-time system scene necessitates the development of efficient strategies for scheduling the work of a garbage collector in a non-intrusive way. We propose a scheduling strategy, time-triggered garbage ...

Now that the use of garbage collection in languages like Java is becoming widely accepted due to the safety and software engineering benefits it provides, there is significant interest in applying garbage collection to hard real-time systems. Past ...

Traditional approaches to enforcing memory safety of programs rely heavily on runtime checks of memory accesses and on garbage collection, both of which are unattractive for embedded applications. The long-term goal of our work is to enable 100% static ...

We present a set of techniques for reducing the memory consumption of object-oriented programs. These techniques include analysis algorithms and optimizations that use the results of these analyses to eliminate fields with constant values, reduce the ...

The scoped-memory feature is central to the Real-Time Specification for Java. It allows greater control over memory management, in particular the deallocation of objects without the use of a garbage collector. To preserve the safety of storage ...

The production of embedded systems is continuously increasing, but developing reusable software for such systems is notoriously difficult, in particular in the case of low-end embedded systems based on 16-bit or 8-bit processors. We have developed a ...

The smallest complete Java™ virtual machine implementations in use today are based on the CLDC standard and are deployed in mobile phones and PDAs. These implementations require several tens of kilobytes. Smaller Java-like implementations also exist, ...

The focus of this paper is on a data flow-transformation called advanced copy propagation. After an array is assigned, we can, under certain conditions, replace a read from this array by the righthand side of the assignment. If so, the intermediate ...

It has long been known that a single ordering of optimization phases will not produce the best code for every application. This phase ordering problem can be more severe when generating code for embedded systems due to the need to meet conflicting ...

When applying optimizations, a number of decisions are made using fixed strategies, such as always applying an optimization if it is applicable, applying optimizations in a fixed order and assuming a fixed configuration for optimizations such as tile ...
