Cradle Technologies explains them, and how to do MPEG-4 Baseline Profile implementation on their multi-core CT3600 processor family.
Class D amp extends high fidelity Product News 10/6/2006 Post a comment Product Review - Touting a step advance in Class D audio amplifiers, JamTech's JM2020 True Fidelity digital amp includes its new sub-ranging pulse width modulator (PWM) technology to significantly extend linearity and dynamic range.
Open Source Embedded Asterisk-based PBX Design How-To 10/4/2006 3 comments Building an embedded IP-PBX represents a significant paradigm shift from existing open source PBX designs that typically use PCI cards on x86 platforms. Until recently, current micro controllers
(e.g. those in the 200MHz ARM & MIPs class) typically lack the DSP
horsepower for multiple channels of speech compression or echo
cancellation that is required for analog line interfaces. The Analog
Device Blackfin chip has changed all this......
Go green young designers Power DesignLine Blog 10/4/2006 Post a comment The need for energy is a constantly growing demand, especially as more countries become energy hogs like the US. Data centers are now prime targets for power management because energy demands are growing dramatically.
PoE systems jack up their flexibility and firepower Product News 10/4/2006 Post a comment Product recap - Significantly expanding their overall flexibility, the latest slew of chips and modules for serving a maturing power-over-Ethernet (PoE) technology demonstrate yet higher levels of integration, more power per port, and system costs across the board that are dropping to half that of the previous generation.
Single-stage Class D amp delivers 300 watts Product News 10/2/2006 Post a comment Product Review - Texas Instruments says its TAS5261, which delivers 300 watts into a 4-ohm load, is the industry's highest power single-chip Class D amplifier stage, more than double the output of any competing device.
Blog Doing Math in FPGAs Tom Burke 2 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
