Singular RCA Adder
Description
A singular RCA adder of one of many designs. Includes inputs A and B, CIN, and COUT. CIN is the side input, COUT is the two-colored 4-long wire, and A and B are the levers at the back.
RCA adder designs are great for redstone beginners - they are simple to explain, build, and use.
However, there is a drawback: RCA has a delay for each adder you add. Each adder has to wait for the last to finish. That is where 'Ripple Carry Adder' gets it's name. It ripples.
This means that not every calculation will take the same amount of time, and thus RCA is not recommended for applications with sensitive timings. If you do plan to use it in something with a clock, like a CPU, probably ensure that the clock is slow, as to give the RCA time. And for pipelined CPUs? Forget it.

1ss 3t CCA
An 8-Bit 3 tick CCA (with Cout and Cin) Features: 1 signal strength minimum, soft input (not hard-powered) and doesn't require both input to have the same signal strength. This tech allows to chain adders together without the need of a repeater in between, which is helpful for circuits like Multiplier. Altough this current layout is hard to connect to each other. This adder is just a proof of concept. Theory and Design by Tosin, made in April 21st, 2024
