Engineers targeting DSP to FPGAs have traditionally used fixed-point arithmetic, mainly because of the high cost associated with implementing floating-point arithmetic. That cost comes in the form of ...

I just received an interesting note from the folks at OptNgn Software. OptNgn (www.optngn.com) produces and sells FPGA coprocessor acceleration libraries and services to customers that need to ...

Although it has found many uses in signal processing, the Fast Fourier Transform (FFT) has taken on even more importance as a fundamental part of the algorithms used for communications protocols based ...

Rodger Hosking, Vice President, Richard Kuenzler, Engineer, Pentek Inc., Upper Saddle River, N.J. For years, field-programmable gate array (FPGA) technology has been a major cornerstone of board-level ...

Engineers have solved a 50-year-old puzzle in signal processing. They've formulated the 'inverse chirp z-transform,' an algorithm related to one that's running on your cell phone right now. It took ...
