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 is going mainstream. Programmability, or rather configurability, will no longer be confined to glue logic, datapath chips, or special processing functions. Instead, programmable ...

We have always had programmable analog circuits. Any circuit that makes outputs change as a function of inputs is in some way programmable. Examples include gain change as a function of voltage or ...

Ernie Smith is a former contributor to BizTech, an old-school blogger who specializes in side projects, and a tech history nut who researches vintage operating systems for fun. When it comes to major ...

Algorithm-driven design is the norm rather than the exception for the modern system designer, often requiring them to incorporate higher performance integrated circuits (ICs). Unfortunately, the ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

Content Addressable Memory (CAM) architectures provide a powerful approach to high-speed data searches by comparing search data against an entire memory in parallel, rather than relying on sequential ...
