The field programmable gate array has always been a different sort of animal in the semiconductor market. While it has evolved from just a bunch of logic gates that can emulate other hardware and ...

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 ...

Californian startup Adaptive Silicon has publicly unveiled the design that the company will use to bring its own form of programmable logic to ASICs. In a break from traditional programmable-logic ...

A bit of history 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 ...

Advanced logic design techniques using field programmable gate arrays (FPGAs), programmable logic devices, programmable array logic devices, and other forms of reconfigurable logic. Architectural ...

In those days, programmable devices consisted of PALs (programmable array logic devices) and CPLDs (complex programmable logic devices), which were essentially small sets of AND-OR planes with ...

Blurring that line slightly is gate array logic (GAL). These devices were a preceursor to the FPGA, with a much simpler structure, and usually in those days UV-erasable in the same manner as an EPROM.

As reported in Advanced Photonics, they developed a large-scale optical programmable logic array (PLA) capable of handling more complex computations.
