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

I mentioned PMC because you said "I have a system where the a PMC card with C6415 act as a daughter board" (see below). I assume you mean a standard PMC form-factor card with 32-bit, 33 MHz PCI interface. > 2) I try external mem in SDRAM. (

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...

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.
