Hello, I have some confusion regarding the multiplication in ADSP 218x. For example, i want to multiply 1.5 * 1.5 which should give 2.25 in assembly language of ADSP 218x. to represent 1.5 , i use the 2.14 format which gives it to be 0x6000. Now when i keep M

Hi, For the first time, I am trying to write C-programs for the ADSP-218x, but it seems that the C-compiler wants to do all math in integer mode. As result of any multiplication z = x*y it uses MR0 as result instead of MR1. How do I get around this? Can I declare a 32-bit vari

Hi, I'm trying to write a program for my ADSP 2189M Ez-Kit Lite board, which takes in data samples from a Codec on SPORT0 and transmits the results over SPORT1 to a binary file. Is this possible? In the ADSP 218x examples that were given with the Visual DSP++ soft

Hi all!! The purpose of my posting is to know if someone had already programmed in C, functions that would handle the flag_in status for ADSP 218x family. Actually flag_in pin is not mapped into any registers in 218x family DSP's. Indeed, I have been trying this, but unsuccessf

Hi, I'm disposing of a complete ADSP-218x development environment, including unregistered VisualDSP++ (R") and a full PCI SummitICE JTAG with other stuff. Cost USD 1000s a few years ago - hopefully will go to a good home now... I used it for one project... http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150466743035 Cheers Nick

Does anyone know if there are internal pull-up or pull-down resistors on the programmable flag pins (PF7..PF0) for the 218x series of processors? If so, are they configurable? How do I program them? What state are they (high or low)? I'm trying write a single software build to run on two different hardware architectures. Both use an ADSP-2188M. On one architecture, the software is suppos...

Hi, Thought the list might be interested in the format used in the .idm files generated under VisualDSP++ 2.0 (ADSP-218x) that are used for idma boot loading. Thanx go to Analog FAE Jeff Sondermeyer and Dana NLN from Technical Support. =======

Hello everyone, I got some DSP boards which use ADSP-218x DSP processor and audio codec AD-1881/AD1819A. I want to use this audio codec for sample based interrupts (without using Autobuffering mode). Can I do it? Are there any sample programs for this need? Regards

I am design the IDMA interface to ADSP-218x, the host need access the PM/DM of DSP chip via IDMA. It is easy to understand how to access the DM, because the DM is 16-bits wide, but when the host need access the PM, I meet a question, the PM is 24-bits wide when the IDMA bus IAD is 16
