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 ...

Using embedded-array programmable logic, it's possible to build multipliers that run faster than previous programmable-logic implementations. With the method shown here, you can make 4×4 multipliers ...

If you've talked on a cell phone, browsed the Internet, or watched a show on 4K TV, you've benefited from field programmable gate arrays (FPGAs). Other examples of FPGAs at work include Google search ...
