Jeff Bier’s Impulse Response—Floating-Point DSPs Catch the Audio Wave

December 08, 2003 |

As we approach year-end, it seems fitting to look back at developments and trends in DSP processors. And it’s an opportune time to do so, since my colleagues and I just completed the latest iteration of our exhaustive (and exhausting) study of leading DSPs. It has been three years since we

At the Microprocessor Forum last month, Renesas and SuperH debuted the latest processor in the SuperH family, the SH-X. The SH-X is a synthesizable 32-bit fixed-point CPU core that is object-code compatible with its 32-bit predecessors, which include the SH-3, SH3-DSP, and SH-4. Renesas expects

At last month’s Microprocessor Forum, Sun Microsystems CTO Greg Papadopoulos predicted that microprocessors as we know them will disappear by 2010. In his view, microprocessors will continue to absorb surrounding chips until the entire computer is contained in a single chip. This

Last month Motorola introduced the MC56F83xx family of control-oriented DSPs. The MC56F83xx is the second processor family based on the 56800E core. It succeeds the DSP56F8xx, which uses the older, slightly less efficient 56800 core. All six members of the MC56F83xx family operate at an
