The CuPIDS project is an exploration of increasing information system security by dedicating computational resources to system security tasks in a shared resource, multi-processor (MP) architecture. Our research explores ways in which this architecture offers improvements over the traditional uni-processor (UP) model of security. There are a number of areas to explore, one of which has a protec...

In a mobile society, more and more devices need to continuously adapt to changing environments. Such mode switches can be smoothly done in software using a general purpose processor or a digital signal processor. However hardware cores only can cope with both throughput and power consumption constraints. Reconfigurable hardware platforms provided by FPGA devices offer partial reconfiguration at...

Future wireless communications networks require flexible modem architectures with high performance. Efficient utilization of application specific flexibility is key to fulfill these requirements. For high throughput a single processor can not provide the necessary computational power. Hence multiprocessor architectures become necessary. This paper presents a multi-processor platform based on a ...

Embedded applications are often more naturally modeled as a set of concurrent tasks, but yet they are often implemented using a single embedded processor. Traditionally, run-time operating systems have been used to simulate concurrency by timesharing the underlying processor and to facilitate inter-process communication amongst the concurrent tasks. However, this run-time approach to multi-task...

In this paper we describe the performance evaluation and comparison of server based “Enterprise Middleware” frameworks on multi-processor multi-core server processor architectures. We experimented a 'single processor quad core Intel Xeon' server processor and a 'dual processor dual core multiprocessor AMD Opteron'. Also we discuss the expected enterprise middleware framework execution performan...

Heterogeneous Multi-core Processors (HMP) are better to schedule jobs as compare to homogenous multi-core processors. There are two main factors associated while analyzing both architectures i.e. performance and power consumption. HMP incorporates cores of various types or complexities in a solitary chip. Hence, HMP is capable to address both throughput and productivity for different workloads ...

This work shows how to port μCOS-II kernel and to build the ARM cortex-m3 hardware platform. This program researches how to drive the basic external devices. This paper gives a detailed discussion that the driver programs of the underlying hardware is how to be expanded into the uC/OS_II to process the tasks from the platform. The applications can make the STM32 processor work normally by calli...

Multi-processor systems are becoming increasingly important in consumer electronics as well as in industrial applications, such as automotive software. Tasks need to share data across processing unit boundaries, e.g., local variables, triggering the need for a communication fabric. Therefore, multi-processor systems are constituted not only by a mere set of processing units, but also by communi...

Most general-purpose multiprocessors are time-shared among multiple users. When a user arrives, s/he requests a submachine of size appropriate to his/her computation ; the processor-allocation algorithm then assigns him/her a portion of the multi-processor of the requested size. This study is motivated by the fact that, as successive users arrive, use a portion of the multi-processor, and depar...

Message-based process architectures are widely regarded as an effective method for structuring parallel protocol processing on shared memory multi-processor platforms. A message-based process architectures is formed by binding one or more processing elements with the data messages and control messages received from applications and network interfaces. In this architecture, parallelism is achiev...
