FPGAs have very large numbers of pins. Ensuring that these are connected and are not shorted to each other requires electrical test vectors and sensing of shorts. Boundary Scan To run up FPGA PCBAs a great solution is boundary scan using a JTAG connection. This lets you drive or sense, in turn, each and every […]

In a recent discussion we were asked about the migration path from MCU/DSP to FPGA. “I am probably not alone when I use MCU/DSP devices to implement control algorithms, protection, logic etc to control the power hardware, using code such as ASM, C or C++, but want the advantages of FPGA. What suggestions do you […]

Touch Screen Dash We acquired a shiny Avnet Display Kit for use with our Microzed board. Our first project on this kit was a basic dash display demo, which ran Xilinx Linux on a Zynq 7Z010 SoC with the aid of some Xylon graphics IP. However we hit a speed bump in our progress. Our […]

One question which is commonly asked is “how do I represent fractional numbers on my fixed-point MCU, DSP or FPGA?” One of the best solutions to this is use of the Q number system. The Q number system is a fixed point system where the available bits are divided amongst the integer bits (those to […]
