Hello! I was wondering whether there is a tool to graphically program the Analog Devices SHARC processor. The SigmaStudio tool does not seem to be available for the processor I have (it is on the EZ-Kit Lite for the ADSP-2136x SHARC processor family). All it has included in the package is Visual DSP++. In particular, I would like your suggestion for a tool which allows making custom blo...

I am using EZ-Kit lite and Visual DSP 3.1. In most examples provided, as default, code is placed into L2 memory. I would like to have my code executed from L1 Instruction memory (0xFFA00000). In my understanding there are two ways how to do this : 1 Program FLASH with the code that includes L1 designated section, and use second-stage-loader that will load this section into L1 space upon res...

Hi guys, For my master's thesis I'm currently trying to implement an active noise cancellation (ANC) system on a ADSP-21369 EZ-KIT Lite. I've chosen the Normalized Leaky LMS algorithm to update (451) coefficients of a FIR filter. In contrast to conventional ANC Systems, the noise I'm trying to suppress is highly repetitive and I have a trigger signal which fires on each repetition. So what...

My first posting to this group... I bought an ADSP2181 EZ_kit Lite off Ebay. It is used as part of a ham radio project called "pic-a-star". I have been enjoying playing with the various example code found on the web too.

Hello!! I am trying to implement an bandpass butterworth IIR filter with fixed point coefficients. I have a wave file that should be filtered with this filter. I do not know how to set the filter characteristics in fdatool(matlab), so that all coefficients be in fixed point arithmetics, because I need them to programming Blackfin 537 EZ-kit Lite.

Dear all, I am trying to interface 2 D/A converters to the SPORT serial port of a ADSP-21065L on an EZ-Kit Lite board. The converters are located on a daughterboard approximately 6 inches away from the EMAFE connector where the serial port signals are tapped. The converters do not receive the serial signals directly. Instead, the serial signals are buffered by a SN74AHC245 fast TTL buffer ...

I have timed reads and writes to the SDRAM and they are within 3 times the number of cy...
