Quadrature Encoder-Decoder Is Implemented In A CPLD

Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

What's Next For Programmable Devices?

Microprocessor and programmable logic design are converging, though they still require a common language. After one of my engineers told me that she had found a typo in her hardware, I thought just ...
