Most if not all of the standard logic blocks come in an inverted form also ... Compare the truth tables for both the OR and the NOR gates shown here. I also recommend learning to think about ...

which is “Could we create our own Periodic Table of Programmable Logic?” If we do, we would want to make a really good job of it. Here’s a starting point table I created in Visio: How about it? Can we ...

multiplexers or a four-input look-up table. It is called the CLB (configurable logic block) and it based on an earlier simpler Microchip peripheral called the CLC (configurable logic cell). “Building ...

Within each device the repeating logic block has eight four-input look-up tables, storage elements and 128 bits of RAM. These logic blocks are surrounded by interconnect and asynchronous data routing ...
