Hi, My pm_data and dm_data are in the memory locations START(0x0000c000) END(0x0000cfff) and START(0x0000d000) END(0x0000dfff) respectively. I want to maximize my dm_data so I transferred my pm_data to START (0x00009400) END(0x00009fff) and my dm_data then becomes START

Hi, just i'm in finishing stage of my algorithm. Now my results are stored in memory(internal or sdram)of BF533. i want to transfer this result to PC and display it there in hyperterminal window using UART. Analog devices gave some example code but it has Tx , Rx option and autobaud (lengthy .asm code). i want the simple example "C" code which is transfering data from

Hi all, I am porting a codec to ADSP-BF533 Ez-kit lite and visualDSP++ 4.0. What I am doing is: =20 1-Since my code is large, I mapped all of the data (including stack and heap) and code to external SDRAM and only frequently used modules to internal L1 SRAM (using LDF). 2-Caches are turned on to improve performance. 3-The encoder is reading an audio file (.wav) from PC using fr...

Hello Sir, I am developing a application in which I want to output the data stored in the SDRAM via PPI Interface. The data speed must be around 30 MHZ. In other words PPI_CLK needs to be 30 MHz. I understand that the PPI is clocked through PF15 pin. I also observed that there is a PPI connector (P8) for PF-15 pin on the board. My questions:- 1) How will I clock the PPI interf...

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'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!

Hi everyone ! I am trying still without success flashing simple vdk project with lwip to internal flash of the bf533 ezkit board. - after reseting the system hangs up, but from debug session works well. Initialization of SDRAM is included. Simple vdk project without lwip stack works well too. Where could be the problem ? Some special settings in linker file ? Looking forward to an ear...

Hi all, I am working on the ADSP-21160 board, I have one PCIDSP board in which 3 ADSP-21160 are embedded,there is host communication to this processors via a PCI bus, so my input is comming through the PCI bus and is stored in the internal memory. I have a memory SDRAM of 64MB. 1. My question is how i can make this external memory 64MB as a shared memory to all

Hi all, I'm doing a project on image processing. I use the CMOS sensor to capture the images. In the cmos sensor main function, I only find the Initialization PLL, EBIU, SDRAM, then the I2C Init, and some I2C read & write registers. then the DMA&PPI init, but when the DMA transfer starts? and where it put the data? I'm a newbie in DSP, I just have a little sence in Visual DSP++. Thank...
