EE & CS: A JTAG/XSVF Library for Arduino
Marcelo Jimenez wrote an Arduino library to apply XSVF patterns on a JTAG interface using the Arduino as a JTAG adapter. It is especially useful for FPGA/CPLD programming. In the example provided in the GitHub repository, the XSVF file is passed through the serial port using a client-side python script. Some time ago I started some similar […]
An example of CPU for FPGAs
August 11, 2012
Zero Characters Left: XENTRAL: A Simple FPGA CPU. The Xentral is an open source example of a CPU that can be synthesized into an inexpensive Spartan FPGA. The HDL source code (written in VHDL) and Xilinx ISE files are here. The project is still at the beginning, the CPU is very simple (e.g. no pipeline) […]
JTAGWhisperer: Arduino as a XSVF programmer
February 5, 2012
Dangerous Prototypes features an interesting project, that is similar to my JTAGduino idea. JTAGWhisperer is a solution to program FPGAs and CPLDs using Arduino and a small client-side Python script. It reads files in the XSVF format, which stands for Xilinx Serial Vector Format and is one of the formats used to program Xilinx chips. […]
