Yesterday Texas Instruments announced its a new DSP, the TMS320C6720. According to TI's press release, this $5.75 part is the "industry's lowest cost floating-point DSP." It sounded good to me until Analog Devices pointed out that it had announced a $5 floating-point DSP almost a year ago! I find it hard to believe that TI didn't know about that part. ADI's part (the ADSP-21375) targets exactly the same markets as the TMS320C6720. Anybody from TI want to explain this one to me?
[Update: TI has an explanation: The ADI part isn't available yet. Since the TI part is sampling now, TI can legitimately claim the low-cost crown… at least for now. TI also questions whether ADI will actually sell the part for $5, but I'm not touching that one.]
[Update, part 2: Whatever the facts are about the ADSP-21375, Analog Devices reports that its ADSP-21261 is available at $5.25 (see page 42 of this product guide), and has been in production for over a year. If you want the lowest-cost floating point DSP on the market, this looks like a good choice. However, it should be noted that the ADSP-21261 is much slower than the TMS320C6720, so the TI part has more bang for the buck.]
