Cosmic: A Model For Multiprocessor Performance Analysis, William W. Carlson, Jose A. B. Fortes Dec 1987

Cosmic: A Model For Multiprocessor Performance Analysis, William W. Carlson, Jose A. B. Fortes

Department of Electrical and Computer Engineering Technical Reports

COSMIC, the Combined Ordering Scheme Model with Isolated Components, describes the execution of specific algorithms on multiprocessors and facilitates analysis of their performance. Building upon previous modeling efforts such as Petri nets, COSMIC structures the modeling of a system along several issues including computational and overhead costs due to sequencing of operations, synchronization between operations, and contention for limited resources. This structuring allows us to isolate the performance impact associated with each issue. Finally, studying the performance of a system while executing a specific algorithm gives insight into its performance under realistic operating conditions. The model also allows us to …


The Honeycomb Architecture: Prototype Analysis And Design, James E. Hoch Dec 1987

The Honeycomb Architecture: Prototype Analysis And Design, James E. Hoch

Department of Electrical and Computer Engineering Technical Reports

Due to the inherent potential of parallel processing, a lot of attention has focused on massively parallel computer architecture. To a large extent, the performance of a massively parallel architecture is a function of the flexibility of its communication network. The ability to configure the topology of the machine determines the ease with which problems are mapped onto the architecture. If the machine is sufficiently flexible, the architecture can be configured to match the natural structure of a wide range of problems. There are essentially four unique types of massively parallel architectures: 1. Cellular Arrays 2. Lattice Architectures [21, 30] …


Robot Control Computation In Microprocessor Systems With Multiple Arithmetic Processors, Bo Li, Shaheen Ahmad Dec 1987

Robot Control Computation In Microprocessor Systems With Multiple Arithmetic Processors, Bo Li, Shaheen Ahmad

Department of Electrical and Computer Engineering Technical Reports

In this paper we address the problem of designing a high performance robot controller with multiple arithmetic processing units (APU’s). One attractive feature about this controller is that a minimum number of special purpose hardware components are needed, and in fact off the shelf components can be used. In the controller described in this paper, one main processor (MPU) schedules a number of APU’s to produce the computational throughput. In this design an efficient scheduling algorithm plays the most important role in the system performance. DF/IHS* algorithm [8] is an efficient algorithm that solves "strong" NP-hard problems of scheduling a …


Calibration Of Wrist-Mounted Robotic Sensors By Solving Homogeneous Transform Equations Of The Form Ax=Xb, Y. C. Shiu, S. Ahmad Dec 1987

Calibration Of Wrist-Mounted Robotic Sensors By Solving Homogeneous Transform Equations Of The Form Ax=Xb, Y. C. Shiu, S. Ahmad

Department of Electrical and Computer Engineering Technical Reports

In order to use a wrist-mounted sensor (such as a camera) for a robot task, the position, and orientation of the sensor with respect to the robot wrist frame must be known. We can find the sensor mounting position by moving the robot and observing the resulting motion of the sensor. This yields a homogeneous transform equation of the form AX=XB, where A is the change in the robot wrist position, B is the resulting sensor displacement, and X is the sensor position relative to the robot wrist. The solution to an equation of this form has one degree of …

2d Modeling Of Bipolar Junction Transistors, J. L. Gray, J. Egley

Department of Electrical and Computer Engineering Technical Reports

The purpose of this report is to summarize the progress to date on the development of a 2D computer model for bipolar junction transistors. The goals of this project, which ends December 31, 1988, can be broken into two main categories and are listed below: Code Modifications 1. Modify existing 2D solar cell simulation code to handle bipolar junction transistors. 2. Incorporate energy balance equations into the computer model. 3. Incorporate transient and small signal ac analyses. Code Applications 1. Assess performance differences between Delco small and large thin epi devices. 2. Evaluate a polysilicon modification of the thin epi …

Residue Arithmetic Vlsi Array Architecture For Manipulator Pseudo-Inverse Jacobian Computation, P. R. Chang, C. S. G. Lee Nov 1987

Residue Arithmetic Vlsi Array Architecture For Manipulator Pseudo-Inverse Jacobian Computation, P. R. Chang, C. S. G. Lee

Department of Electrical and Computer Engineering Technical Reports

Most Cartesian-based control strategies require the computation of the manipulator inverse Jacobian in real time at every sampling period. In some cases, the Jacobian matrix is not of full column or row rank due to singularity or redundant robot configuration. This requires the computation of the manipulator pseudo-inverse Jacobian in real time. The calculation of the pseudo-inverse Jacobian may become extremely sensitive to small perturbation in the data and numerical instabilities, when the Jacobian matrix is not of full column or row rank. Even if the Jacobian matrix is of full rank, the ill-conditioned problem may still plague the computation …


A New Method Of Image Compression Using Irreducible Covers Of Maximal Rectangles, Y. Cheng, S. S. G. Iyengar, R. L. Kashyap Nov 1987

A New Method Of Image Compression Using Irreducible Covers Of Maximal Rectangles, Y. Cheng, S. S. G. Iyengar, R. L. Kashyap

Department of Electrical and Computer Engineering Technical Reports

In recent years there has been a tremendous spurt in research and activity in finding efficient compression techniques for image processing applications. Particularly when an image is structured over a non-rectangular region it is always advantageous to define a method of covering a region by minimal numbers of maximal rectangles. Towards this objective, we analyze the binary image compression problem using irreducible cover of maximal rectangles. We also give a bound on the minimum rectangular cover problem for image compression under certain conditions that previously have not been analyzed. It is demonstrated for a simply connected image that, the irreducible …

Destination Tag Routing Techniques Based On A State Model For The Iadm Network, Darwen Rau, Jose A. B. Fortes, Howard Jay Siegel Oct 1987

Destination Tag Routing Techniques Based On A State Model For The Iadm Network, Darwen Rau, Jose A. B. Fortes, Howard Jay Siegel

Department of Electrical and Computer Engineering Technical Reports

A "state model" is proposed for solving the problem of routing and rerouting messages in the Inverse Augmented Data Manipulator (IADM) network. Using this model, necessary and sufficient conditions for the reroutability of messages are established, and then destination tag schemes are derived. These schemes are simpler, more efficient and require less complex hardware than previously proposed routing schemes. Two destination tag schemes are proposed. For one of the schemes, rerouting is totally transparent to the sender of the message and any blocked link of a given type can be avoided. Compared with previous works that deal with the same …


Preliminary Report On High-Performance Computational Structures For Robot Control, Mahibur Rahman, David G. Meyer Oct 1987

Preliminary Report On High-Performance Computational Structures For Robot Control, Mahibur Rahman, David G. Meyer

Department of Electrical and Computer Engineering Technical Reports

In this report we present some initial results of our work completed thus far on "Computational Structures for Robot Control". A SIMD architecture with the crossbar interprocessor network which achieves the parallel processing execution time lower bound of o( [a1n ]), where a1 is a constant and n is the number of manipulator joints, for the computation of the inverse dynamics problem, is discussed. A novel SIMD task scheduling algorithm that optimizes the parallel processing performance on the indicated architecture is also delineated. Simulations performed on this architecture show speedup factor of 3.4 over previous related work completed for the …
