RTL Architecture The original version of the frame grabbing PCB used an iCE40 HX8K FPGA. This turned out to be a little small for the features I wanted to add. I managed to get it to a state where it would capture images from the Boson 320, but everything was hardwired together, and not easy to alter or reuse. In order to improve module reuse and extendability a standard interface should be used....
The new hardware for the Boson Frame Grabber will be based around the Lattice ECP5 family. Lattice make available a free IDE for this FPGA assuming you are not using a model with embedded SERDES. Since we are not, it鈥檚 perfect for our application. ...
In this part I want to talk about the firmware, or code, this device will need in order to operate as I want. ...
In part 1, I discussed the version 1 prototype I had built. Just after ordering the PCBs for that project I decided to start thinking about miniaturizing the hardware. ...
