NXP CoolFlux BSP's 12-bit computation has pros and cons for low-power baseband
The new CoolFlux DSP core from NXP targets low-power baseband applications with some unusual features, particularly its complex, 12-bit computational capabilities. BDTI's analysts took a look inside the core and while it has many strengths, they raise some interesting questions concerning its viability in that space.
And Stellaris Makes Four: But TI's expanding CPU line may work against it
With the purchase of Luminary Micro and its Stellaris family of Cortex-M3 MCUs, Texas Instruments now has four distinct CPU architectures and is the only company with a CPU/DSP continuum. However, while it's an increasingly formidable MCU player, the incompatibility of these four CPU lines may be a problem.
Analysis: APTX intro's cognitive audio encoder, drops hardware division
APTX recently announced its new apt-X Scalable that can select an encoding scheme based on the signal's characteristics. Oddly, the company also sold its hardware division. BDTI's Jeff Bier takes a look at both the technology and business implications.
Analysis of Microchip's PIC32 library
With the 32-bit MIPS 4K core, Microchip is now competing with the ARM juggernaut so offering optimized DSP libraries for the PIC32 is a good strategy. BDTI examines the library, in particular it looks at how it stacks up against ST Micro's ARM Cortex-M3-based STM32 library offering.
BDTI benchmark results for Toshiba's Venezia platform
An analysis by BDTI of the two processors in Toshiba's Venezia mobile multimedia platform, the MeP media embedded processor and the IVC2 SIMD coprocessor, shows how they stack up against Texas Instruments' 'C55x, ADI's Blackfin and the ARM Cortex A8.
Inside Ceva's high-performance XC core for 4G handsets, infrastructure
In February CEVA announced a new family of high-performance licensable DSP cores, the CEVA-XC family, targeting 4G cellular applications, including LTE and WiMax -- for both handsets and infrastructure. BDTI went inside and took a look at the company's performance and features claims.
Impulse Response: In the face of downturn, innovation lives!
There's been a lot of bad news of late, but despite it how it may look, innovation is not dead, far from it. In fact, the cycle of innovation that's currently underway may be what pulls us out of this downturn.
OMAP 4 ups performance with dual Cortex-A9 cores
Texas Instruments recently announced its next-generation application processor family, OMAP 4 for smart phones and mobile internet devices (MIDs); BDTI went inside to explore its design and what makes it tick so well.
