Optimization of memory system in Real-Time Embedded Systems

Code space is a critical issue in designing of software for real-time embedded systems. The memory system often determines a great deal about the behavior of an embedded system: performance, power, and manufacturing cost. A great many software techniques have been developed to optimize software to improve these characteristics. Since much of the code for embedded systems is compiled once and then burned into ROM, the software designer will often tolerate much longer compile times in the hope of reducing the size of the compiled code. This paper surveys techniques for optimizing memory behavior of real-time embedded software . Key-words : embedded systems, real-time, memory, compiler , optimization , cache
