Digital Stop Watch
Below is a digital stop watch built around timer IC LM555 and 4-digit counter IC with multiplexed 7-segment output drivers (MM74C926). IC MM74C926 consists of a Continue reading
Quadratic Convergence of a Nonsmooth Newton-type Method for Semidefinite Programs Without Strict Complementarity
We consider a Newton-type method for the solution of semidefinite programs. This Newton-type method is based on a semismooth reformulation of the semidefinite program as a nonsmooth system of equations. We establish local quadratic convergence of this method under a Continue reading
HDL Code Analysis For ASICs in Mobile Systems
The complex work of designing new ASICs today and the increasing costs of time to market (TTM) delays are putting high responsibility on the Continue reading
3D Image Segmentation Implementation on FPGA using EM/MPM Algorithm
In this Project, 3D image segmentation is targeted to a Xilinx Field Programmable Gate Array (FPGA), and verified with extensive simulation. Segmentation is performed using the Expectation-Maximization with Maximization of the Posterior Marginals (EM/MPM) Bayesian algorithm. This algorithm segments the Continue reading
Chaos-based Random Number Generator in Finite Precision Environment
Yet having a very long history, how to generating good random number sequences still remains as a technical challenge. Although some mechanical ways, such as tossing a coin or rolling a dice, are commonly accepted as good random sources, they are obviously not been able to Continue reading
Implementation Of Goldschmidt’s Algorithm With Hardware Reduction
Division algorithms have been developed to reduce latency and to improve the efficiency of the processors. Floating point division is considered as a high latency operation. This papers looks into one such division algorithm, examines the hardware block diagram and Continue reading
High-Speed Floating-Point Divider with Reduced Area
This paper presents a new implementation of a floating-point divider unit with a competitive performance and reduced area based on proposed modifications to the recursive equations of Goldschmidt algorithm. The Goldschmidt algorithm takes advantage of parallelism in the Newton-Raphson method with the Continue reading
Gradient algorithms for quadratic optimization with fast convergence rates
We propose a family of gradient algorithms for minimizing a quadratic function f(x) = (Ax; x)=2 ¡ (x; y) in Rd or a Hilbert space, with simple rules for choosing the step-size at each Continue reading
