Hi.  I have acquired an ADSP-21469 EZ-Kit lite.  I downloaded Visual DSP++ 5.1.2 with a test flight license key.  It appears only emulator and simulator options are available.  Please advise on how to register for an evaluation license key.

I am using Visual DSP++ version 5.0 with Update 10.1.   I am compiling programs for the ADSP-21489, and I am running into a problem with the compiler.   As I am adding features to my program, it is growing in size. At a certain point, the compiler gave the following message:     ----------------Configuration: TestCode - Release----------------… (Show more)

In order to more closely match a Matlab implementation, much of our low-frequency work is done in floats.  However, the conversion of floating point numbers to fract32s is emerging as a problem.   The default rounding done when converting from float (single) to fract32 appears to be of the type "_float32_to_int32_round_to_zero".  As I understand… (Show more)

Hi all,   I'm working on a BF537 VDK application that uses interrupts. I've been reading through the "VisualDSP++ 5.0 Kernel (VDK) User’s Guide" and the "ADSP-BF537 Blackfin Processor Hardware Reference" trying to understand the best way to configure and control interrupts.    Is there a difference or preference between using… (Show more)

Hi All,           For Example consider addition is a simple program and this progran executed in VDSP++ 5.1 software. For this how could measure the MIPS.

Hi, I recently received my ADSP-21489 EZ-Kit (EVAL-21489-EZLITE Evaluation Board | Analog Devices) and have been trying to run the example programs included with Visual DSP++. I have successfully installed Visual DSP++ and entered the license included with the EZ-Kit, I then succeed in making a session, however when I try to activate the session… (Show more)

Hi All, I've been looking at ways to improve performance in a project which uses a BF537. I came across App Note "Tuning C Source Code for the Blackfin® Processor Compiler": http://www.analog.com/media/en/technical-documentation/application-notes/EE-149.pdf    I noticed that the date is from May 26, 2003.    Does this App Note still apply? Are… (Show more)

Using Visual DSP++ 5.1.2 and running on a 21479 I have a problem with the resolution of single precision floating point accuracy. Could anyone point me to how under project options/processor the double size works. If I change the double size from 32 bit to 64 bit   the LDR produced increases from 298kB to 387kB even though I have no doubles… (Show more)

Hello,   I'm trying to debug a older Sharc (ADSP-21161) VisualDSP 2.0 DXE with the CCES. I have converted it with the elf2elf.exe. This functions and I can load the DXE.   But I have two problems: After loading, the program starts itself running, but I don't have enabled it in the debugger configuration. I want only download it and then start… (Show more)
