04 Aug 2004TL;DR: In this article, a fixed-point filter circuit is used to filter fixed point texture data by providing a fixed point input path that bypasses the format conversion and a floating-point accumulator.
Abstract: Floating-point texture filtering units leverage existing fixed-point filter circuits. Groups of floating-point texture values are converted to products of a fixed-point mantissa and a scaling factor that is the same for each texture value in the group. The fixed-point mantissas are filtered using a fixed-point filter circuit, and the filtered mantissa is combined with the scaling factor to determine a floating-point filtered value. Multiple floating-point filter results may be combined in a floating-point accumulator circuit. The same fixed-point filter circuit may also be used to filter fixed-point texture data by providing fixed-point input path that bypasses the format conversion and a fixed-point accumulator.

TL;DR: This paper is concerned with the application and implementation of genetic algorithm and simulated annealing methods for the development of a fast microprocessor-based automatic antenna tuning unit, providing the facility to adapt to changes in load impedance, temperature or environment.
Abstract: The paper discusses and compares the application of genetic algorithm and simulated annealing methods to LC filter tuning. Specifically, the paper is concerned with the application and implementation of these methods for the development of a fast microprocessor-based automatic antenna tuning unit, providing the facility to adapt to changes in load impedance, temperature or environment. A number of simulations were carried out to evaluate the relative performance of these algorithms. Finally, experimental results are presented where the simulated annealing algorithm was used to control a commercial impedance matching device in real time.

TL;DR: More than eight years have passed since DeVries et al. reported the first attempt at installing SAW (Surface Acoustic Wave) filters in a TV set as discussed by the authors, and SAW IF filter development has been continued by several companies and TV receivers incorporating SAW filter have been placed on the market since 1977.
Abstract: More than eight years have passed since DeVries et al. reported the first attempt at installing SAW (Surface Acoustic Wave) filters in a TV set(1). In Japan, SAW IF filter development has been continued by several companies and TV receivers incorporating SAW filter have been placed on the market since 1977.

TL;DR: In this paper, reconfigurable MEMS capacitors are integrated with on-chip inductors and transistors to design reconfigurable VCO and filter circuits that can reconfigure from one frequency to another are of interest in multifunction radios.
Abstract: RF building block circuits that can reconfigure from one frequency to another are of interest in multifunction radios. Reconfigurable MEMS capacitors are integrated with on-chip inductors and transistors to design reconfigurable VCO and filter circuits. Electrothermal actuation of the MEMS capacitor leads to >400 MHz change in operating frequency.
