7 warning signs that you should be concerned about your IP provider Design How-To 12/19/2002 Post a comment Reusing semiconductor intellectual property (SIP or IP) blocks is no longer a luxury for the designers of complex chips it is a necessity. As mask costs skyrocket and qualified engineering resources become increasingly scarce, chip design teams are incorporating IP reuse strategies into virtually every chip development plan in order to minimize design cycles, reduce chip respins, and meet time-to-revenue goals.
IP strategies proliferate as SoC complexity grows News & Analysis 12/19/2002 Post a comment Merging previously designed circuit blocks into new system-on-chip designs seems like a sound way of controlling the complexity of SoC projects and leveraging the relatively scarce resources of the circuit design community at least on the surface. But reuse of intellectual property (IP) is shaping up as a complex design approach with its own unique characteristics.
Removing Residual Jitter from OC-192 Measurements Design How-To 12/19/2002 Post a comment Performing accurate jitter measurements is a must in OC-192 designs, where even 1 ps of jitter can have detrimental effects. Here's some techniques to improve jitter measurements by removing residual jitter created by the test instrument.
Target Detection using Matched Wavelets Design How-To 12/19/2002 Post a comment This article develops a technique for designing a band-limited wavelet to match a given signal. The scaling function is then derived from the wavelet spectrum such that the generated scaling function and wavelet satisfy the conditions for an orthonormal multi-resolution analysis. This technique of designing matched wavelets is useful in pattern recognition, coding, and compression applications that require wavelets that closely match the signal of interest.
Power Play News & Analysis 12/17/2002 Post a comment Power management has become an industry staple as the need to switch and convert different voltage levels and concerns about power consumption have increased. But the power management sector, encompassing parts like regulators, rectifiers, and power transistors, has struggled recently as poor market conditions force suppliers to cut prices and refocus their market strategies.
Efficient Algorithms for MPEG-4 Video Decoding Design How-To 12/17/2002 Post a comment Efficient, programmable video decoding is critical for emerging mobile devices. J. Geoffrey Chase and Christopher Pretty from the University of Canterbury, New Zealand describe efficient algorithms for MPEG-4 video decoding and quantify the impact of accelerating co-processors for creating fully programmable MPEG-4 decoding solutions.
