Design and Simulation of High Performance Parallel Architectures Using the ISAC Language
نویسندگان
چکیده
Most of modern embedded systems for multimedia and network applications are based on parallel data stream processing. The data processing can be done using very long instruction word processors (VLIW), or using more than one high performance application-specific instruction set processor (ASIPs), or even by their combination on single chip. Design and testing of these complex systems is time-consuming and iterative process. Architecture description languages (ADLs) are one of the most effective solutions for single processor design. However, support for description of parallel architectures and multi-processor systems is very low or completely missing in nowadays ADLs. This article presents utilization of new extensions for existing architecture description language ISAC. These extensions are used for easy and fast prototyping and testing of parallel based systems and processors.

Efficient Reverse Converter for Three Modules Set {2^n-1,2^(n+1)-1,2^n} in Multi-Part RNS
Residue Number System is a numerical system which arithmetic operations are performed parallelly. One of the main factors that affects the system’s performance is the complexity of reverse converter. It should be noted that the complexity of this part should not affect the earned speed of parallelly performed arithmetic unit. Therefore in this paper a high speed converter for moduli set {2n-1, ...

متن کاملEvaluation of the performance of parallel-hole collimator for high resolution small animal SPECT: A Monte Carlo study
Introduction: Image quality and accuracy of in vivo activity quantification in SPECT are affected by collimator penetration and scatter components, especially in high energy imaging. These phenomena highly depend on the collimator characteristic and photon energy. The presence of penetrated and scattered photons from collimator in SPECT images degrades spatial resolution, contr...
متن کاملDesign and Implementation of a High Speed Systolic Serial Multiplier and Squarer for Long Unsigned Integer Using VHDL
A systolic serial multiplier for unsigned numbers is presented which operates without zero words inserted between successive data words, outputs the full product and has only one clock cycle latency. 
The multiplier is based on a modified serial/parallel scheme with two adjacent multiplier cells. Systolic concept is a well-known means of intensive computational task through replication of fu...
