Dear DSPers, I need to design a communication scheme for C6415 to be able to communicate with a host processor. I am wondering someone could explain to me how to do this for C6415 ? Host -------- (1) put information to DSP internal memmory. (2) t

Hi, If I'm not mistaken, when the C6415 connected to a host system as a PCI target device, the host or any other master device on the PCI bus can access to C6415's memory. By setting the DSPP register, theoretically (and practically??) the bus master can acc

I heard today from one of our engineers that C6415 has only 1x, 6x, and 12x mulipliers available for its onchip PLL. For the 500 MHz version of the device, how do we hit that rate, or should we only run 480? -Jeff

Hi DSP'ers, I am currently trying to build a dsp driver for linux to work with our c6415. I have managed to load some code into the dsp's memory over the PCI interface and can verify the code is correct, however the old (hex5x) conversion utility used to have a start address f

Hi All, We just had prototype communication board using C6415. When I implemented the driver on WinNT 4.0 for this board and test it from host, I found: 1. the performance is not that good as I expect: 5Mbytes/s PCI read, 50Mbytes/s PCI write. 2. PCI burst write is not w

Hello, Does anyone has an idea on how I could transfer large blocks of data (>64KB) through the PCI interface of a C6415 DSP using the DSP MASTER mode ? If I split the transfer in 64KB blocks, it will require some processing by the DSP-CPU (interrupt servicing

Hi, I am developing a new board utilizing TI's C6415 chip and H.110 Framer. I have some troubles with the McBSP port when the the serial port is running at 8M. Basically all the three McBSP ports connect to the local stream of the H.110 Framer, the serial port clock and frame is synchronized to the external clock and frame signal fr

Hello, I'm writing a C6415 app with CCS2.1. I have some problems with the linker. The __STACK_SIZE symbol is defined by the linker and used to initialise the stack pointer. If I look in my .map file, I see that this symbol is placed at the same addres

We're working with multiple C6415 board, and we've noticed that when C641x devices are held in Reset, they actually generate more heat than when running. The chips work though, and do what they're supposed to when running (at 720 MHz). This sounds counter-intuitive, and is unlike all the other Texas Inst DSPs we've worked with. Has anyone else encountered

Dear All, I'm confused with the DAT module of DSP/BIOS. I'm using C6415 chip. According to the help, before begin any DAT_copy / DAT_fill tranfer, the DAT_open(...) must be called to allocate an exclusive channels for the module. Is that means the DAT

Hi there. I'm using C6415 in my circuit with the EMIFA connected to an SDRAM on CE0 and an FPGA on CE2 (configured as a programmable synchronous memory), both having the same bus width (64 bit). I was wondering how an EDMA transfer would work between these two spaces. Since the bus is shared, I'm guessing that part of the data from the source (or all of it) is stored in the DSP's internal memo...

I am writing a C++ application on C6415 using CCS 3. I use a C library for which I have to provide an interrupt handler (thus, that function will be called using the C calling convention). However, this handler interacts with a C++ object and has to be defined in a C++ file. Is there a way to inform the compiler/linker to use C calling convention

Hi, We're moving to C6416 from C5416 for one of our products. I've seen at the C6000 CCS page that this release of CCS supports simulator only for C6414,C6415,C6416. Is that correct? Thanks. --  -------------------------

I get the correct FFT output "shape" of a say sine wave using DSP_fft16x16t with C6415, but the it is in Q15. How can I accurately scale it back to a float value? Do I just have to find the correct value by referring to say the output of Matlab or other software? -Jeffrey
