Hi! I'm having a problem with my thesis. I need to know how to use the external memory of ADSP-21065L. My thesis is about MP3 Decoder using ADSP-21065L with audio enhancements. An MP3 file should come from an external memory, i.e. SDRAM, SD card. Now I don't know how to interface this to the dsp board. I would really appreciate any help from you. Thank you!

Please refer to the chapter-10 of ADSP-21065L User Manual. The minimum size supported for SDRAM is 16 MBytes. If you use any size less than 16 MBytes (as you seem to be currently asking), you will not be able to use some of the address ranges of SDRAM - because these address ranges will be aliased to some other address ranges. For example with 8MByte SDRAM (as you are asking), (1) remaining ...

Hi! I'm planning to use a flash drive for memory expansion of ADSP-21065L. To interface this (flash drive) to the DSP board, I will use a USB female port to 9 pin female serial port connector. The 9 pin female serial port is to be connected to the EMAFE of the DSP board and the USB female port to the flash drive. How can I connect the USB port to the serial port? Will that be a simple ...

Hi! I'm new with VB and VisualDSP++. I am doing a GUI that should be able to access the ADSP 21065L's memory but I encountered lots of problems doing it. The major one is this: I used the ExecuteTcl() command passing just the basic TCL command "DSPrun" as parameter. The exact code is: Option Explicit Dim result as Variant Private Sub cmdRun_Click() exe = ExecuteTcl("dsprun", ...

Hi everybody, I am using an ADSP 21161N Ez kit and I have a serial port dilemma. I used the EE-191 note to implement an uart to transfer datas from my DSP to my PC. This transfer is based on serial ports 1 and 3. My problem is that I also need serial port 1 and 3 to configure my ad1836 codec. (using SPI is not possible because of an anomaly on my ad1836 component version) Nevertheles...

Hi, I am new to ADSP-BF533. I'm working on a image processing project for video input on the Ez-Kit Lite board. Color video data are captured and stored in the BF533 external SDRAM in the following order: Cb0 Y0 Cr0, Y1, Cb2 Y2 Cr2, Y3, Cb4 Y4 Cr4, Y5, Cb6 Y6 Cr6.... where each Y, Cr and Cb is 8 bits. My problem is this: I want to do this kind of transferring: Cb0 Y0 Cr0, Cb2 Y2 ...

Hi, I have downloaded a melp1200 c code from the internet and am trying to port it adsp-2188. There is an array declared in qnt12_cb, by the name of res256x64x64x64 which has a size of 0x2300. The maximum segment which I can define is of 8k. I am using overlays. Is there a way to fit this array into the memory without decomposing it??? Other wise I will have to make segments of this array ...

Hello, I am working on the ADSP EZ-kit Lite 21369. I am wondering how to make the board working as a stand alone system ? I could generate a .ldr file from the loader utility. But how can a load this file on the board that it works stand alone ? Shall I use the Tools/Flash Programmer in VDSP++ ? Or an other method ? Have anyone a clue to help me ? thanks a lot, A.
