Hi, i have no experiece about dsp or fpga (instead i know microcontrollers), so i have some questions: 1. What are the differences about DSP and FPGA? When dsp is better than fpga? I heard that dsp is better for floating point numbers: is it true?why? 2. for image processing, what is the better? thanks

Hello ALL I am new DSP programming & Code composer. I have to build a windows application which communicates with TI DSP by RS 232 PORT. TI DSP is connected with a EEPROM 25LC050 through SPI.

Ok, folks, I did ask a similar question before but that was long ago. Meantime I have read articles such as one about a VoIP phone designed without DSP. Made me wonder: Why were they touting that absence of a DSP? Anyway, recently I went over the DSP offerings. Again. Not much new stuff to write home about. Prices are still $3 and up for the low end. Power consumption is still high. Som...

On TI OMAP-L138 DSP, there is a system register which contains "DSP reset vector" (HOST1CFG::DSP_ISTP_RST_VAL). For some reason, the lower 10 bits of this register are set to 0. Is this the address from which the DSP starts executing, or is this a pointer to memory location from which the DSP reads the starting address? I couldn't find any explanation in the docs. Presented this ques...

Hello all, What would you experts do if you want to perform image compression (I am thinking jpeg), on a low power board? The data is captured from an image sensor and needs to be transmitted elsewhere. Would you use a MCU bundled with a DSP or would you use two separate MCU and DSP chips? I was thinking about using a PIC with nano watt technology along with a low power DSP from TI. Or ...

Interested in opinions and thoughts as to which DSP's might be good/best for real-time image processing. We currently use FPGA's. It would be interesting to learn what can be done with DSP's. Are there any that have efficient ways to implement such things as FIR filters, for example, or matrix transforms, etc.? How about dealing with SDRAM/DDR SDRAM frame stores? Are there any that can ...
