Embedded systems need to respect stringent real time constraints. Various hardware components included in such systems such as cache memories exhibit variability and therefore affect execution time. Indeed, a cache memory access from an embedded microprocessor might result in a cache hit where the data is available or a cache miss and the data need to be fetched with an additional delay from an...

With the development of embedded systems and the mobile internet, embedded systems are equipped with more and more memory capacity. Memory reliability becomes a focus to us. Though parity checking has been applied in embedded systems, it only can detect errors, but cannot correct them. Therefore, researching better data protection becomes an important topic for the development of embedded syste...

Multiprocessor system-on-chip (MPSoC) is an attractive solution for increase in complexity and size of embedded applications. MPSoC is an integrated circuit containing multiple instruction-set processors on a single chip that implements most of the functionality of a complex electronic system. While embedded systems become increasingly complex, the increase in memory access speed has failed to ...

Flight data recorders (FDRs, or black boxes) generate data that is collected on an embedded memory device. A well-known difficulty with these devices is that the embedded memory device runs out of space. To avoid getting into this problematic situation, the software of the FDR is designed to operate in a watchful mode, constantly working to minimize the use of memory space; otherwise a larger F...

The objective of this paper is to analyze how the memory management configuration in Linux influences run-time performance of embedded systems. Extensive experiments confirm that the configuration of the memory management subsystem significantly affects the overall execution time, the memory performance, and the system call overhead. Our quantitative experimental results will help embedded syst...

Redundancy repair of high-density commodity Flash memory is an effective technique to improve per-wafer yield by trading-off increased die size and increased time at wafer-probe for the ATE system to analyze the failing bits and make the necessary repairs. In embedded Flash, where densities are typically much lower and test requirements more diverse, the benefit of redundancy repair is less cer...

As the capacity and density of embedded memories have rapidly increased, the probability of memory faults will increase. That results in yield drops and quality degradation.Yield improvement of embedded memories have become very important.Yield refers to the percentage of good die on the wafer. For embedded memories Built-In-Redundancy-Analysis (BIRA)is used to achieve optimal repair rate and y...

The ultra-low power embedded devices are generally batteryoperated and have limited data memory. The efficient use of memory is very important as the data memory of the device is limited. Run-length encoding has attracted much attention as an important data compression technique because of its simplicity and potentially low complexity. The present paper describes a Modified Run-Length Encoding ...

Low power embedded system requires effective memory design system which improves the system performance with the help of memory implementation techniques. Application specific data allocation design pattern implements the memory storage area and internal cell design techniques implements data transition speeds. Embedded cache design is implemented with simulator and scheduling approaches which ...

embedded systems, the energy consumed by the data memory organisation represents a very large cost. We present a method to explore the design space of an object-oriented application in order to optimise the energy consumption and the footprint of the memory. Because we are working at the class design level, we can exploit the functionality of the system and focus on optimising the data related ...
