Your favorite thing about redstone:
My favourite thing about redstone is that it is a unique way to make
circuits that only exists in minecraft and just about any circuit can be
made using redstone such as a calculator.
A build you have made which demonstrates redstone knowledge (This is your trial build):
4 bit ALU
Explain what your build does in detail:
My build performs arithmetic and logic operations on binary data. It is an ALU,
arithmetic logic unit. The alu uses binary circuits called full adder circuits to
compute the sum of two binary data inputs known as input A and input B. The full adder circuits each have 2 inputs of nbits A and B, a 1 bit input for carry in, 1 output for a carry out bit, and lastly an output for sum which is the binary sum of both inputs a and b. A 4 bit alu will be used which has 4 full adders, the least significant bit of the sum is where the first full adder is and it’s carry out output connects to the carry in input of the full adder of the next bit and this pattern continues until the fourth bit is reached. This type of alu uses the ripple carry adder design, the down side to this is that the outputs are not synchronized and are generally slower at larger scales but it’s still functional for some binary processing purposes. There is a XOR logic gate for each bit of both inputs A,B, the outputs of each xor gate is connected to their corresponding bit, the A input of these XOR gates will be the inputs for inputs A and B, and the B inputs will be the invert function input. With XOR logic gates added to the alu circuit, it is possible to invert the inputs. To invert input A there will be a 1 bit input for the invert A function which outputs to all the B inputs of the invert XOR gates for the A operand, There is also the invert B function. There are 2 more input that this alu has, one bit for the OR function, one bit for the FC, flood carry funtion. The OR function input works by disabling AND gates within each full adder circuit thus stopping the full adders from producing a carry out signal. The Flood carry function works by connecting to the carry in of each full adder circuit which results in all the output bits being flooded as 1.
