Hi all, I am a fairly new embedded programmer and this is my first post on this forum. I am working with a 6713 DSP and in my current project I am reading data from some FIFO's connected to the EMIF bus. My problem is the performance of the EMIF I have measured the time it takes to read from the EMIF and i have confirmed these findings with the simulator. I'm excecuting the folowing code: ...


Does EMIF width matter?

Hello, 1. Is the usable EMIF width limited by the memory size that will be used? i.e. Can a 16MByte SDRAM be used with a 64bit EMIF? 2. Also I want to make that there will be a performance degradation if the 32bit-EMIF to 16MByte SDRAM is used in place of 64bit-EMIF to 1

Hello Everyone, Does anyone know what is the interface used to connect the Virtex-5 FPGA and the the DSK6416 EMIF ? I know the connector to be used on the EMIF side is a Samtec TMS 140-32-S-D-LC but I have no idea about interfacing that with the Virtex-5. The no. of pins on the EMIF side and the the FPGA Virtex 5 EVM aren't the same. Thanks, -- Varun

Hello all, I was wondering if anyone have ever written a driver for the EMIF on TMS320C6455 DSK. I want to stream data to the EMIF interface using DSP/BIOS, however, I cannot use just Tasks or periodic interrupts as they are too fast for the RTOS. Therefore I need to do some kind of buffering. I read through a lot of BIOS manuals, and it looks like you can use pipes and even write a device driv...

Hello, I have seen a couple of threads mentioning that FIFO can be connected to EMIF port in synchronous mode. However, from TI application notes it appears that the EMIF does not support the synchronous FIFO mode, and therefore the EMIF must be configured to operate in asynchronous mode. As a consequence, the transfer rate can not be as high as a synchronous rate. Can someone please...
