PART 3/3 MY PROJECT: I want to pave the way for FPGAs to be usable in everything from laptop/desktop computers to phones (if the static power consumption gets better). I have some very interesting ideas of what an average user could do with in system FPGAs that can be reconfigured at runtime. My main target is fixing the huge tangled JTAG mess. I mentioned earlier that even though the JTAG standard is pretty solid, everything built on it and around it are highly non standard. There is one more problem; there were standards to address how to build boxes to let your PC talk JTAG since that is not the IEEE's area. Each company has their own JTAG Controller which is often USB. Each controller only works with the Company's software and only with the company's chips. The good news is that there is no physical reason these controllers can not talk to all JTAG devices. Each of them have custom USB protocols for how to make the box talk JTAG, and only the company's software knows how to talk to it. The limitation here is the software on the PC and not the controller itself. All we need is documentation on the controllers USB protocol, which is where my project started. As a final note on JTAG controllers, almost all of them require being loaded with firmware every time they plug in. This means that you have to have the proprietary firmware available. But since this firmware is not allowed to be distributed by anyone other than the company that created it, even if we know the secret USB protocol, we can not use these controllers with our own open tools out of the box without writing custom open firmware for each one. I first started documenting JTAG controller protocols. This is available on my github (though it needs to be cleaned up). Next I started work on an open tool for talking JTAG to all chips independent of what JTAG controller is used. I only support a few chips for now, but all you have to do to add support another JTAG controller is write a driver and all supported chips will work with it (independent of manufacturer). To address propriatary firmware issue, I started writing my own open source replacements and have a stable (though limited functionality) version of the Xilinx Platform Cable controller available on github. And I am working on firmware for digilent boards (including the Atlys). My next step is to rewrite my tool in something other than python (likely C though I have a fantasy of Rust). The future version will not require controllers to be USB (and will support controllers that use ethernet, PCIe, etc), will support more than just JTAG (Debug Wire, SPI, etc), and likely be a daemon that keeps track of all jtag hardware. I want to see tools like OpenOCD (provides GDB interfaces to embedded systems, etc) to replace its dated controller architecture with calls to my daemon. I want to unify how all of these devices are communicated to so we have something to use when we get configurable FPGAs on the PCIe bus so the kernel or user software can configure them as needed.
