The 8721 PLA, or programmable logic array, was one of the chips that had to be invented to make the Commodore 128, the last of the 8-bit computers that formed the leading edge of the early PC ...

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… ...

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 ...

Consider two examples. At one end is Lattice Semiconductor’s family of programmable power controllers (Figure 1). These multifunction chips control both the sequencing and the trimming of the several ...

Large-scale optical programmable logic array for two-dimensional cellular automata. Credit: Wenkai Zhang (Huazhong University of Science and Technology), edited Optical computing aims to replace ...

Finally, based on the 8-bit full adder, we built a 5KB in-memory logic array capable of executing logic computations and simulated it using EDA tools. The simulation results demonstrated that the 5KB ...

Large-scale optical programmable logic array can execute complex models like Conway’s Game of Life, marking a significant advancement in optical computing Researchers have long sought to harness ...
