step 2 of building a redstone computer (cite word for word)
PENTUPLE POINTS
The ALU we will be building can perform four important operations on two inputs and return a correct output. A, B, being both 8-bit inputs
There can also be multiple ALUs inside a computer, as some programs require a lot of operations to run, which do not depend on the previous operations (so they can be threaded) so delegating them to different ALUs could significantly speed up the program.
binary adder
Adding two numbers
Example: do 10 subtract 9
1. 0000 1001(9 in binary, we want -9, not 9)2. 1111 0110(Invert 9, so that all 0s are 1s and 1s are 0s)3. 1111 0111add one (this the two's complement of 9)4.0000 1010(10 in binary)+1111 0111add two's complement of 9 (aka -9)----0000 0001result (10 + (-9) = 1) (there is an overflow, this just means that the result is not a negative number)
This poses the complexity of signed numbers.[1] This is a weight to the binary number to assign it as a positive or negative number. Whether the result is a negative or positive number is determined by the overflow flag. If there is an overflow, this means that the number is positive and otherwise, negative.
To implement this, you can ask the ALU to do 3 operations. To do A subtract B, the operations are
Operation: A SUB B
Multiplying two numbers
Multiplication is repeated addition, so the easiest (inefficiently) is to add A to a variable B amount of times.
Here's pseudomachine code for it
Operation: A * B
However, there are more efficient ways of multiplication. A good method is to repeatedly bitshift the first number to the location of each 1 in the second number and sum it.
There are underscores to mark indents, since padding with 0s are less intuitive. subscript 2 means in binary, and decimal numbers are also in bold
__ __113 (notice that there are 2 1s)x_ 101111----__ __11We shift 112 by 010 since the 1st bit of 10112 is 12+_ _110We shift 112 by 110 since the 2nd bit of 10112 is a 12+1 1000We shift 112 by 310 since the 4th bit of 10112 is a 12----the 3rd bit of 10112 is 02 so we do not add a 112 there10 000133 (result)
so this is more efficient for larger numbers.
Operation: A * B
Don't forget that
<< A (bitshift to the left) is effectively, A * 2
and
>> A (bitshift to the right) is effectively, A / 2
If the numbers are predictable or the CPU must do a lot of similar numbers in bulk, consider using a look-up table to quickly get results to frequently called multiplication. Is this a way of hard-coding your answers and is used in extreme cases.
Step 2: Building an Arithmetic Logic Unit (PRACTICE)
Step 3: Instruction set and machine architecture (THEORY)
This is pretty fun, this part.
Elaborating on Chapter 2: Instruction Set, we will be creating one for ours.
For the MASIC Computer, the computer which we are building, has an 8-bit system, so that means each instruction on each slot of the stack memory will be 8 bits. The stack memory is the memory where any information can be stored and is on the RAM. There will be a counter, called the program counter, which increments by 1 every cycle. A cycle is the CPU fetching the instruction, decoding the instruction (finding out what to do with the instruction) and executing the instruction (doing what it tells it to do). Then it moves on to the next one by incrementing the program counter and reading the information at that location in the stack memory.
So each byte in the stack memory has 8 bits for us to work with.
