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 ...

Visual dsp 3++ problem. Even After a software reset (while working on=20 session name ADSP 21061 EZ-KIT VIA HPPCI)I find the values of register=20 file holding some garbage value. Since software resets processor=20 status I am expecting register values to be zero.I scan through the=20 forum and what I find there is (I presume it is) that a procedure=20 should be written to ensure register fi...

Hi, I am using BF561 for my video application. I've used SDRAM to store the input frame,and used MDMA to transfer the data from SDRAM to L1 memory. I can transfer only 5 lines at a time, But my application needs the entire frame at one strech. where can i find the driver files to do the frame processing regards, manimekalai
