Compact code generation is very important for an embedded system that has to be implemented on a chip with a severely limited amount of size. Even though on-chip data memory optimization technique has been given more attention, on-chip instruction memory optimization should not be neglected. We propose in this paper some algorithms for a memory offset assignment for embedded DSP processors in o...

Peripherals fail. Yet, modern embedded systems largely leave the burden of tolerating peripheral failures to the programmer. This paper presents Phoenix, a semi-automated peripheral recovery system for resourceconstrained embedded systems. Phoenix introduces lightweight checkpointing mechanisms that transparently track both the internal program state and the external peripheral state. These mec...

Effective memory utilization is critical to reap the benefits of the multi-core processors emerging on embedded systems. In this paper we explore the use of a stream model to effectively utilize memory hierarchies. We target image processing algorithms running on the Analog Devices Blackfin BF561 fixedpoint, dual-core DSP. Using optimized assembly to effectively use cores reduces runtime, but a...

Nowadays, Java is used in all types of embedded devices. For these memory-constrained systems, the automatic dynamic memory manager (Garbage Collector or GC) has been always a key factor in terms of the Java Virtual Machine (JVM) performance. Moreover, in current embedded platforms, power consumption is becoming as important as performance. Thus, in this paper we present an exploration, from an...

Flash memory can be a viable solution for the future embedded systems. Embedded systems usually carry database as a part of embedded software. It is well known that flash memory is far faster than usual hard disk storages especially for read however it takes much time for flash memory to delete than to read or to write. For a database system, index tree on flash memory has been widely studied f...
