Re - architecting GPS for mobile phones
Existing GPS technologies were designed for in-car personal navigation devices (PNDs), for which power savings are not so important, and as GPS moves into the mobile handset, there is a need to rethink how and where the technology is implemented and how the GPS functions are controlled Details... more »

 

Drive your large LCD with PPDS
There is a need for a robust and reliable LCD interface solution to transmit through less data lines working at higher frequency. Point-to-Point Differential Signaling (PPDS) ensures reliable data transmission from the timing controller to the column driver/driver ICs through fewer data lines compared to the traditional multi-drop architecture.

Multiply efficiently in wireless base stations
A key feature of WiMAX system design is the support for OFDM. FPGAs make it extremely easy to implement OFDM transmitters and receivers in discrete time using IFFT and FFT, respectively. This article focuses on the reduction and optimal implementation of multiplier blocks in FFT and FIR implementation for WiMAX base stations. Details... more »
