Clinical decision making is a complicated process. It is based on medical knowledge derived from medical books and literature and on data obtained from various clinical trials and diagnostic tests; however, it is also dependent on experience, judgment, and reasoning, which are functions of the human brain. In many situations, human decision making is not available, and in these situations, inst...

Strassen S algorithm is an efficient method for mulliplying large matrices. We explore various ways of mapping Strassen ' s algorithm inlo reconfgurable hardware that contains one or more customisable instruction processors. Our approach has been implemented using Nios processors with custom inslrucfions and with custom-designed coprocessors, taking advantage of the additional logic and memory ...

We keep providing signicant advances in the state of the art of real-time analysis and multiprocessor scheduling. Our methodologies and tools aim at bringing innovative s...

In the inverter circuit, there exists a specific on-off time in each power transistor. As such, to prevent short circuit of two switch devices on upper and lower bridge arms, dead must be set pulse width modulation (PWM) sinusoidal (SPWM) signals. this paper, an intellectual property (IP) core that can introduce high-precision arbitrary length into PWM or SPWM signals is designed increase preci...

JPEG2000 is a recently standardized image compression algorithm that provides significant enhancements over the existing JPEG standard. JPEG2000 differs from widely used compression standards in that it relies on the Discrete Wavelet Transform (DWT) and uses embedded bit plane coding of the wavelet coefficients [1]. Due to the bit-oriented processing techniques used in the standard, full implem...

This paper focuses on identifying defects in a handloom silk fabric using image analysis techniques such as first order statistical features. Any disparity in the knitting process that leads to an unpleasant appearance or dissatisfaction of the customer is termed as a defect in the fabric. Even today, the defect detection in a silk fabric is done using skilled manual labour. An automated defect...

As increasing the clock frequency leads to unmanageable heat and power dissipation the search is on for another way to get more power efficient and faster embedded systems. Given that chip area is also a constraint, we investigate the addition of a custom instruction to the processor instruction set which enables the execution of an efficient complex division. We have implemented software for c...
