چکیده

Efficient layout of code and data sections in various types/levels of memory in an embedded systems is very critical not only for achieving real-time performance, but also for reducing its cost and power consumption. In this paper we formulate the optimal code and data section layout problem as an integer linear programming (ILP) problem. The proposed formulation can handle: (i) on-chip and off-chip memory, (ii) multiple on-chip memory banks, (iii) single and dual ported on-chip RAMs, (iv) overlay of data sections, and (v) swapping of code and data (from/to external memory). Our experiments demonstrate that, for a moderately complex embedded system, the optimal results produced by our formulation took only a few minutes on a PC, and it matches, in terms of performance and on-chip memory size, with a hand-optimized code/data layout which took 1 manmonth.

Integrative Cell Formation and Layout Design in Cellular Manufacturing Systems

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...

Side channel parameter characteristics of code injection attacks

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...

A Continuous Plane Model to Machine Layout Problems Considering Pick-Up and Drop-Off Points: An Evolutionary Algorithm

One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...
