Hello new to DSP so please try not to flame me to much. For a specific audio application I have in mind I have narrowed my selection down to the Analog Devices Blackfin ADSP-BF532SBSTZ400 Why this part? - It's cheap - it comes in a LQFP and I don't want to deal with BGA's for a prototype - it has two SPORTS that I need, because I'm looking at 6ch in and 6ch out. I need to do this...

Hi, I am evaluating several DSPs for a multimedia application, such as DaVinci (Texas Instruments), Nexperia(NXP), Blackfin (Analog Devices) an so on. I have noticed that some DSPs belonged to TI have a VICP (Video & Image coprocessor) which is like a "black box" for programmers and it is only available for Third Parties of TI: (1) Is this right? What are the limits for using that coproc...

Currently, I have a project that uses the Blackfin DSP. A 8-bit A/D will do undersampling (at 1.6384MHz) of an IF signal which is down-converter from standard stereo FM broadcast. There are quite a few standard FM demodulators, e.g. baseband delay, phase-adapter, mixed type and PLL demodulator. It seems the mixed demodulator should have the best performance among those four. Is there any other ...
