The design of a specialized computer architecture for qualitative simulation is presented. Our interest focuses on the hardware design of an application-speciic computer architecture which is composed of programmable processors (digital signal processors TMS320C40) and application-speciic integrated circuits (FPGAs). Two design strategies are considered to improve the performance. Primitive fun...

Hathi-2 parallel computer is a transputer-based distributed multicomputer with a programmable processor interconnection network. The computer is intended for research of parallel programming methods and implementation of parallel algorithms for various applications. The custom design of the computer is an attempt to improve and enhance the basic transputer arcitecture, and at the same time, to ...

In the process of hardware optimization, physical queries requiring laboratory experiments are often necessary. This is similar to optimization using software where queries are made to a computer model. In both the laboratory optimization and optimization using computer models, queries come at a cost: laboratory time or computer time. Finding efficient searches using a small number of queries o...

This paper describes our experience with using hardware description languages (HDLs such as VHDL) in the sophomore level Computer Architecture course for Computer Science (CS) majors. In our approach, we leverage the students’ understanding of Object Oriented Programming (OOP) to introduce programmatic specifications of computer components such as multiplexors, adders etc. Students will be expo...

Computer memory is central to the operation of a modern computer system; it stores data or program instructions on a temporary or permanent basis for use in a computer. In this paper, various memory management and optimization techniques to improve computer performance are reviewed, such as the hardware design of the memory organization, the memory management algorithms and optimization techniq...

Advances in computer hardware often have little impact until they become accessible to programmers using high-level languages. For example, the IEEE floating-point arithmetic standard provides various rounding modes and exceptions, but it is difficult or impossible to take advantage of these from most high-level languages, so the full capabilities of IEEE-compatible hardware are seldom used. Wh...
