Hello, I'd like to apologize for my english but it isn't my native speech. I'm a french student and I have some problems for understanding the the using of ADSP Sharc 21061: 1) I have to control and receive informations from an High Speed ADC (40 Msps) in 10 or 12 bits with the Sport1 of the DSP. But I have absolutely no idea the way of doing that... -I read in forums that the localisation of Sport1 is the J4 connector but in reading my documentation I found the J2. Which one is the right? -I don't know how to configure that Sport for receiving and storing 10 or 12 bit trames at 40 Mhz, how to use that Sport for controling the ADC (clock and control signal). 2) I have to do amplitude-demodulation from the signal I receive, but I didn't find a simple way for doing that. How could I proceed? If you have some informations, C-codes, internet links, or tips which could help me for my project... Thanks for your comprehension. |

Hello diozdi, an astronaut would say: "Houston, I have a problem." :) Seriously, if your ADC samples at 40 MHz * 12 bits = 480 Mbps, how are you going to squash that into the 40 Mbps serial port of a 21061?
