Sharc ADSP 21364   This is a crazy question about libraries. visual studio 5.1.2   1/ I have created a simple project, A 2/ I have created a simple library, B 3/ In the project I have opened the ldf file and added the B.dlb file and updated dependencies. this entry turns from grey to the correct purple color. 4/ In the project A I have… (Show more)

Hi, I am writing a program using the ADSP-21489 Ez-Kit, which uses a large delay line array that is more than the on-chip memory can accommodate. I would like to allocate this array to the external SDRAM (MT48LC16M16A2P). In my research on the topic I have seen this done via pragma marks such as this: “#pragma section (“seg_ext_dmda”) int… (Show more)

Hi. I've found this code in the documentation, for the dot product in assembly : --- /* dot(int n, dm float *x, pm float *y); Computes the dot product of two floating-point vectors of length n. One is stored in dm and the other in pm. Length n must be greater than 2.*/ #include <asm_sprt.h> .section/pm seg_pmco;   .GLOBAL _dotASM;… (Show more)

My setup is one I2S (48kHz, 32bit word length) as master enters SRC0 of SHARC21489, and SRC0's output clock is generated by PCG from CCLK IN (12.288MHz). But it seems SRC0 can't work as expected, its output are always 0s.   So my question is: Can ASRC HW module in 21489 accept I2S data with 32bit word length?

Hi, I am working with the ADSP-21489 Ez-Kit on an audio project, and am basing my design off the I2S Talkthru example that I found here: https://ez.analog.com/message/253453?commentID=253453#comment-253453    In this example all 8 of the input and output channels are used (16 channels total), when I only require stereo input and output for my… (Show more)

Hi, I am looking into using the Sharc family of processors for audio development. I am designing a series of DSP effects for guitar.    Can you recommend a good development board for this purpose? Also is there any sort of guide you can recommend for getting started with audio on the Sharc, such as a list of materials needed for programming in… (Show more)

Hi,   I am new to SHARC processor family, and have not been able to find a manual explaining the registers list and their functions. Surprisingly enough I haven't been able to find one on the internet. Any help is appreciated.   Also i was trying out the Block Based talkthrough example provided. When the processor is halted, via the IDE, the… (Show more)

Hello,   I am developing an application for the SHARC-21469 using VisualDSP++ Update 10.   When building the application, the assembler issues the following info and warnings for some assembly files:   Anomaly Actions   Detecting: 15000006 15000005 15000011 15000012 15000004   Working-around: 15000016 15000010   [Warning ea2547]… (Show more)

Hi there.   Can somebody tell me why the following code takes 33 cycles instead of the expected 18 cycles?   "LCNTR = 3, DO (PC, 6) UNTIL LCE;\n\t" " F12 = F3 * F4, F11 = F11 + F12, F3 = DM(I0, M0), F4 = PM(I8, M8);\n\t" " F12 = F3 * F4, F11 = F11 + F12, F3 = DM(I0, M1), F4 = PM(I8, M8);\n\t" " F12 = F3 * F4, F11 = F11 + F12, F3 = DM(I2, M2),… (Show more)

Hi, I am trying to port the ADSP-21469 BSP Example Project "AD1939_Block_Based_Talkthru_192kHz" to the ADSP-21489 Ez-Kit. I have seen posts saying this is easy to accomplish, but none with specific instructions on how to get started. How can I accomplish this?   Thanks!
