Case Study: Creating Top-Notch Tools for Signal Processing

December 12, 2005 |

Signal processing is becoming important in an increasingly broad range of embedded systems. As signal processing workloads become more widespread, these workloads are increasingly assigned to embedded processors that were not designed with signal processing in mind. Because these processors

It’s so tempting. You need to figure out how much processing power you’ll require to implement a particular video compression algorithm, and there, out on the Web, is the data you need—but for a slightly different scenario. Perhaps the data is for a smaller frame size than

Last week TI unveiled its first “DaVinci”-branded processors, the TMS320DM6443 and the TMS320DM6446. These processors target home entertainment, surveillance, and other video applications. The two chips are similar in many respects. Each chip contains a 300 MHz ARM9E general-purpose

Digital video has emerged as one of the hottest markets for DSPs and other types of processors. As a result, many processors now target digital video applications. However, not every processor is up to the challenge. Digital video applications have heavy computation and memory-bandwidth loads,

Those of us who earn our livelihoods working with embedded signal processing software understand that optimization isn’t just something we do for fun (though often it is quite fun). Optimization is usually done to meet hard real-time constraints, trim product costs, or stretch battery

Last week StarCore unveiled the first details of its next-generation DSP core family, the SC3000. The most notable new feature is the family’s high clock rate: According to StarCore, SC3000 cores will achieve a clock rate of 1 GHz in a high-performance 90 nm process. In comparison,

Last week ARM announced its latest processor core, the Cortex-A8. The Cortex-A8 is the highest-performance ARM processor to date, and it differs in many ways from older ARM cores. Perhaps the most obvious difference is the name: Instead of the traditional naming scheme (ARM7, ARM9, ARM11,
