2818 Audio DSP Dev Kit Price Set to Rise

Noah Vawter writes: "The 2181 EZ-Kit Lite development community will be changed forever after January 31st, 2002. This is because we have heard the price of the kit will increase from $89 to >$200 (for marketing reasons). The kit contains a 40 MIPS DSP and a stereo, CD-quality codec. A group of experimental internet musicians has been developing audio and music software for the kit for years in an open source fasion. They have developed several effects algorithms , a MIDI interface , PalmOS control software , and a Flash File system for it- all of which are free to download with source code. But get one asap if you want to get in on the fun cheaply!"

Price change for marketing reasons

[Snowfox]

I'd wager that the announcement of an increase is what's being done for marketing reasons. (Hook, line, sinker for Slash's editors.)

Nothing like being told "This is your last chance! Buy now!" to spur people who wouldn't have bought it in the first place into an impulse/panic purchase.

Trumpion dsp sdk in a D-link 110 player?

[calabr1]

I have an d-link 110 mp3 portable player( with trumpion dsp).It is the same price as this board but portable, it has an usb port and even has a microphone (too bad it doesn't record in mp3 but in a proprietary format). The board holds a Trumpion dsp and a soldered flash memory...
Where can I find the develompent tools?

Here is the DSP [trumpion.com.tw]

It's a 2181, you moron!

2181. 2181. 2181.

2181 EZKIT Alternatives

[pinkyMice]

Just looked at the Analog Devices, and the list price of the 2181 EZKIT is $295. However, ALL of the EZKITs seem to be in that price range. If you are going to get an EZKIT, take a look at the following:

ADSP-2191 EZKIT. Code compatible with the 2181, but faster core. Also has 24 bits of memory address, as opposed to 14 for the 218x core. This is useful for longer delay lines, for reverbs and such.

ADSP-21065L EZKIT. 32 bit SHARC, can operate in integer or floating point modes. Probably can't run 2181 code without some work. However, there are some EXCELLENT audio application notes available; check out http://www.analog.com/library/applicationNotes/AdA udio/21065L_Audio_Tutorial.pdf. No crappy Schroeder reverbs here; we're talking Dattoro/Griesinger reverbs, with full source code!

ADSP-21161 EZKIT. Similar to 21065, but with SIMD capabilities. Audio application notes at http://www.analog.com/library/applicationNotes/dsp /32_Processors/21161_Audio_Tutorial.pdf, although the code doesn't seem to be SIMD-optimized.
