lowcost dsp tms320xxx

Hi All,

I'm searching some DSP with float-point ALU, or fixed point 32bits multiplication.
Anybody have some sugestion ?


Thanks in advance

Texas Instruments (www.ti.com) sells floating point DSP (C67xx family) and Floating-Point digital signal Controllers (TMS320F283xx ) which are a sort of hybrid between DSP and MCU.
Also Analog Devices (www.analog.com) produces floating point DSP (SHARC and Tiger SHARC families). I don't know if Freescale (formerly Motorola) has floating point DSPs.
If floating point support is not a must, you have only to choose according to your requirements among a wide variety of processor families provided by the above producers.

Thank you.

Well, I worked at a part of development of a product wich uses blackfinn, and I think it's very hard to work, due it seem to be a microprocessor instead microcontroler. Do you know about cost of TMS320xxx familly DSPs ?

regards

Hello,
currently I am working with C6416 device. It is not a cheap processor: it costs more than 200$.
To discover pricing and availability for other devices go to
https://focus.ti.com/dsp/docs/dspsu...9&techDoc=5&familyId=132&documentCategoryId=5
and query for the CPU you are interested in.
