K-loops - Loop Transformations - Bok av Ozana Silvia Dragomir - Häftad

K-loops - Loop Transformations - Bok av Ozana Silvia Dragomir - Häftad

The focus of this dissertation is on kernel loops (K-loops), which are loop nests that contain hardware mapped kernels in the loop body. The reader will find here methods for improving the performance of such K-loops, by using standard loop transformations such as unrolling and pipelining, for exposing and exploiting the coarse grain loop level parallelism.The targeted applications are from the signal processing domain, where large kernels in the innermost loop are common. Examples are the JPEG,..

Phase Locked Loop Based Integer N Frequency Synthesizer - Bok av Jyoti P Patra & Umesh C Pati - Häftad

Phase Locked Loop Based Integer N Frequency Synthesizer - Bok av Jyoti P Patra & Umesh C Pati - Häftad

The present work describes about a phase locked loop (PLL) based integer n frequency synthesizer for unlicensed national information infrastructure (UNII) lower band. It covers a frequency range of 5.15 - 5.25 GHz which is used by IEEE 802.11a. For simplification of design, the channel spacing of the frequency synthesizer is taken to be 5 MHz. The frequency synthesizer consists of a phase frequency detector (PFD), a charge pump (CP), a second order loop filter (LP), a voltage controlled oscillator..

Optimized loop filters in fixed WiMax PLL using LMI method - Bok av Hala El-Khozondar, Hatem Elaydi, m.fl. - Häftad

Optimized loop filters in fixed WiMax PLL using LMI method - Bok av Hala El-Khozondar, Hatem Elaydi, m.fl. - Häftad

Achieving an optimal design of phase-locked loop (PLL) is a major challenge in WiMAX technology in order to improve system behavior against noise and to enhance Quality of Service (QoS). A new loop filter design method for PLL is introduced taking into consideration various design objectives such as small settling time, small overshoot and meeting Fixed WiMAX requirements. Optimizing conflicting objectives is accomplished using semi-Definite programming (especially Linear Matrix Inequality (LMI))..

The X-Slits Stereo - Bok av Ludvk Pardubick & Ludvik Pardubicky - Häftad

The X-Slits Stereo - Bok av Ludvk Pardubick & Ludvik Pardubicky - Häftad

The X-Slits camera is a special type of camera, where the projection ray of space point is defined as the ray intersecting this point and two lines in P3, called slits. The X-Slits camera is one of the so- called non-central cameras. The images of the X- Slits camera can be constructed from a sequence of perspective images taken by a sideways moving pinhole camera. The X-Slits images can be used for image based rendering (IBR) or for stereo reconstruction. The X-Slits projection model is more complicated..
