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 ...

Using EPROMS And EEPROMs As Programmable Logic With Lisp

That EPROMs, EEPROMs and kin can be used as programmable logic should probably not come as a major surprise, but [Jimmy] has created a Lisp-based project that makes using these chips as a logic array ...

Programmable Logic: To HDL Or Not To HDL?

Strategies for EDA tool usage will change course as gate levels, and ultimately costs, rise in programmable logic designs. For designs below 25,000 gates, the basic tools from logic vendors and many ...
