Tip: Overcoming multicore programming challenges with LabVIEW
Here's how LabVIEW handles thread synchronization seamlessly, and how visual debugging tools further aid in developing parallel software.
Tip: Using data parallelism in multicore LabView
Here's how to use data parallelism to speed up inherently serial tasks when running LabView on a multicore CPU.
Embedded DSP Software Design on a Multicore SoC Architecture: Part 1
Robert Oshana outlines the hardware/software constraints involved in building an embedded media device based on a DSP/ARM multicore-based System-on-Chip. First up, the hardware building blocks.
Lossless Compression of Audio Data - Part 1
Part 1 of this series focusing on lossless audio data compression offers an introduction and overview of the technique, and a discussion of some of its key principles.
SDR Basics Part 3: Transmitters
This book excerpt provides a sample of the comprehensive information available in this text. The book aims to be a complete desk reference and features input from numerous industry-leading experts. This part covers transmitters for software defined radio.
picoChip's femtocell reference design supports WiMAX Wave 2, IO-MIMO
picoChip claims it is the first to deliver an integrated PHY and MAC Wave 2 solution in a single chip -- the picoArray-based PC205 processor.
ARC decoder IP extends MP3 battery life
ARC International has started sampling an MP3 decoder core for its Sound Subsystem that operates at under 7 MHz and dissipates less than 0.46 mW of power.
