Embedded ICs: Expanding the possibilities
|
2000-11-06 |
| As designs start to proliferate in the more complex 16-, 32-, and 64-bit realms, the days of selecting a mild-mannered, off-the-shelf processor may be numbered. That's because semiconductor vendors are unleashing a new crop of heavy-duty cores, beefed up instruction sets that add DSP support, and system-on-chip options. This article will explore what's driving these trends and look at a few of the latest offerings |
