Your favorite thing about redstone: Redstone helps me practice building and testing computer circuits, as well as applying computer science knowledge from my college courses.
A build you have made which demonstrates redstone knowledge (This is your trial build): A 4-bit ALU using a CCA.
Explain what your build does in detail:
The base of the build is a 4-bit CCA, which uses two inputs A and B, carry-in signal Cin, and a cancel signal Ca, to output the addition of two 4-bit numbers to main output O and carry output Cout. The inputs are compared through an xnor gate, which sends two signals: one is negated and sent to the xor to be compared to the carry-in signal, and the other serves as the carry-out signal. The inputs are also compared via a nor gate, which disables the cancel signal when true. The carry will only pass when the carry-out signal is enabled and the cancel signal is disabled.
Each input is compared by its own xor gate to an inversion signal. When this signal is enabled, A!/B! will be sent as input to the system, rather than A/B. There is also a carry input, which adds 1 to the xor gate before the first output. Using B! in combination with this carry input will generate 2's compliment from a standard binary input, allowing for subtraction. There is also a flood carry input, which sets each Cin value to 1, negating the main outputs. Finally, there is a function which replaces A xor B with A or B, allowing for bit-wise operations.
