Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. T...

Compressed representations of programs can be used to improve the code density in embedded systems. Several hardware decompression architectures have been proposed recently. In this paper, we present a method of decompressing programs using software. It relies on using a softwaremanaged instruction cache under control of the decompressor. This is achieved by employing a simple cache management ...

| This paper addresses instruction-level paral-lelism in code generation for DSPs. In presence of potential parallelism, the task of code generation includes code com-paction, which parallelizes primitive processor operations under given dependency and resource constraints. Furthermore , DSP algorithms in most cases are required to guarantee real-time response. Since the exact execution speed o...

Quasi-Orthogonal Space-Time Block Code presents an up-to-date, comprehensive and in-depth discussion of an important emerging class of space-time codes, called the Quasi-Orthogonal STBC (QO-STBC). Used in Multiple-Input Multiple-Output (MIMO) communication systems, they provide transmit diversity with higher code rates than the well-known orthogonal STBC (OSTBC), yet at lower decoding complexit...
