The first practical programmable logic chips, known as PLAs (programmable logic arrays), became available in the mid 1970s. Things really took off though when MMI introduced a simplified series of ...

Then Xilinx came up with the SRAM-based field programmable gate array (FPGA) that could hold from 1,000 to more than 5,000 logic gates. Unfortunately, using all those gates while still connecting them ...

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 arr… ...

MathStars re-programmable FPOA can process logic functions at a clock rate up to 1 gigahertz, much faster than current commercially available programmable logic devices. MathStar's flagship product, ...
