12 years agoHi Gwall,
thanks for your reply. I really love HW design, and i would like to learn a lot in that matter. That kind of board would give me a great opportunity. I have done some research on Cyclone V developement kits and found out that: On http://www.altera.com/products/devkits/altera/kit-cyclone-v-gx.html There are for DDR3 32-bit data bus two x16 devices and one x8 device for ECC support. Mainly on CV boards Altera uses: MT41J128M8JP-125:G MT41J128M16JT-125:D They are not available on Digikey, however there are: MT41J128M8JP-15E MT41J128M16HA-15E Which are only slower (667MHz compared to 800Mhz). So i assume that it doesn't make a difference and i could use those ICs. My questions: 1. Would i be able to use reliably only two x16 ICs without x8 for ECC ? 2. I assume that for HMC there are dedicated pins. It's more efficent to use HMC and SMC, so why use on http://www.altera.com/products/devkits/altera/kit-cyclone-v-e.html SMC instead of HMC? I don't know any specifics and wasn't looking for them, however i suppose that SMC utilizes much, much more FPGA resources. 3. What about DDR3 lenght matching. What do you think about the picture on that blog: http://www.fedevel.com/welldoneblog/2012/05/so-dimm-ddr3-length-matching-diagram/ ? It could be used also for ICs ? 4. Should I use T-Branch topology for DDR3 with Cyclone V? 5. What about embedded ARM cores as i see know. I thought that there was only one, but it seems that it's dual core. http://www.altera.com/devices/processor/arm/cortex-a9/software/proc-soc-embedded-design-suite.html Can i use standard JTAG for Cortex-A9 and be able to do all my developement? What about Linux Application Development ? 6. What would be the easiest and cheapest connection of some SDI interface, SD-SDI. I also found http://www.microtronix.com/hsmc-daughtercard-solutions/hdmi-receiver-transmitter-hsmc-daughtercard-1 but for this kind of solution i can see that "The AD9889 requires the use of an I2C IP Core for device configuration." So i wouldn't be able to copy hardware and use it quickly and easily. Thanks, madness
