Design of Shared Memory Controller Device Driver in Embedded System

design of an analog fuzzy logic controller chip

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Performance Studies of RHODOS ’ Operating System Embedded Distributed Shared Memory

Distributed Shared Memory (DSM) is an abstraction for shared memory on a system where the memory is physically distributed which allows programmers to take advantage of the increased processing power provided by a Clusters of Workstations (COW). We have integrated DSM into the RHODOS operating system rather than to put this paradigm on top of an operating system, as have other researchers. RHOD...

Design of Virtual Memory Compression System for the Embedded System

The embedded system has less fast CPU and lower memory than PC(Personal Computer) or Workstation system. Therefore, the embedded operating system is designed to efficiently use the limited resource in the system. Virtual memory management of the embedded Linux have a low efficiency when page fault is occurred to get a data from I/O device. Because a data is moving from the swap device to the ma...

PCIComm: A Linux Device Driver for Communication over PCI Shared Memory

Computing clusters are often comprised of a set of full computers connected by a network. Several technologies are emerging to more tightly couple the CPUs in clusters. This paper addresses a Linux device driver for an inter-node communication system. It describes a system utilizing commonplace existing hardware to perform I/O between embedded computers communicating over a shared PCI bus. The ...
