MATLAB-to-C Translation, part 2: Complex functions and C interfaces
Part 2 of this 3-part series looks at complex functions and the role C interface constraints play in the translation process.
Efficient radix-4 FFT on StarCore SC3000 DSPs
Here's how to implement an efficient radix-4 FFT, using the StarCore SC3000 as an example.
Analysis: Qualcomm's 1 GHz ARM "Snapdragon"
BDTI examines Qualcomm's 1 GHz ARM-based Snapdragon platform, and explains how it compares to competitors like OMAP3430 and i.MX31.
Lossless Compression of Audio Data - Part 3
The third and final installment of this series continues its discussion of practical system design issues and concludes with a look at some examples of lossless audio data compression software systems.
Video quality assessment with motion and temporal artifacts considered
Most video quality metrics, including PSNR, JND and MSE, do not incorporate motion information. Yet motion, and motion errors play a crucial role in the perception of video. A new paradigm for video quality assessment takes into account artifacts arising from spatio-temporal processes including ghosting behind fast-moving objects, block artifacts from faulty motion compensation, mosquito effect near moving edges, jerkiness, and smearing from slow acquisition.
SIGNAL CHAIN BASICS #3: ADCs - Terms defined
Understand the basics of transforming analog signals to digital via A/D converters, and how factors such as resolution, precision, and quantization affect results.
TI rolls DaVinci for HD transcoding
The TMS320DM6467 targets video transcoding in products such as set-top boxes and media gateways. It can simultaneously encode and decode multi-format HD video at resolutions up to H.264 HP@L4.
MATLAB-to-C tool get major upgrade
Catalytic's MATLAB-to-C tool can now generate C code for over 300 MATLAB functions, including functions from the signal processing, communications, imaging, and math toolboxes.
ARC readies energy saving cores
ARC International is readying a range of cores, dubbed Energy PRO, that adds active power management capability to its line-up of IP cores. The cores come validated with Cadence Low Power Solution and Common Power Format (CPF) through a partnership between the ARC, Cadence and Virage.
