Simultaneous Multi-processor Cores for Efficient Embedded Applications

Simultaneous Multi-processor Cores for Efficient Embedded Applications

This paper introduces Simultaneous Multi-Processor (SMP) cores. These SMP cores offer a high performance, efficient application target for the embedded system developer. SMP cores can be reprogrammed like a microprocessor in response to application requirement changes. They do not require caching, or superscalar instruction processing, greatly reducing silicon size and energy consumption. Also ...

Efficient 16-bit floating point interval processor for embedded applications

In the last ten years, interval techniques [1, 2] have allowed original solutions for many problems in engineering to be proposed, see, e.g., [3]. One of the main features of interval techniques is their ability to provide guaranteed results, i.e., with a verified accuracy or which are numerically proved. Consider for example, a bounded-error parameter estimation problem: the value of some para...

Ensuring Schedulability for Embedded Multi-cores

Energy-Efficient Multi-processor Implementation of Embedded Software

This paper develops energy-driven completion ratio guaranteed scheduling techniques for the implementation of embedded software on multi-processor system with multiple supply voltages. We leverage application’s performance requirements, uncertainties in execution time, and tolerance for reasonable execution failures to scale processors’ supply voltages at run-time to reduce energy consumption. ...

Low Power Java Processor for Embedded Applications

This chapter presents a low power architecture of a Java processor. We show that the use of techniques like pipeline and the implementation of the stack in a register bank instead of using the main memory allow aggressive reduction of power dissipation, with a very small area overhead. Besides, thanks to the forwarding technique and to the specific stack machine organization, huge power savings...
