Decoder in computer architecture instruction manual

Decoders are digital ICs which are used for decoding. In other words, the decoders decrypt or obtain the actual data from the received code, i.e. convert the binary input at its input to a form, which is reflected at its output. It consists of n input lines and 2^n output lines. fileslib. A common type of decoder is the line decoder which takes an n-digit binary number and decodes it into 2 n data lines. The simplest is the 1-to-2 line decoder. The truth table is A is the address and D is the dataline. D 0 is NOT A and D 1 is A. The circuit looks like 2-to-4 Line Coder Only slightly more complex is the 2-to-4 line decoder. The computer architecture is concerned with how the CPU acts and uses the computer memory.

Note that the op-code is just a number, often just a byte. For instance, the addition instruction might have byte value 0x01, the subtraction might be 0x02 and so on. However, note that the numbering is somewhat arbitrary. It doesn't in itself say what the instruction does - this is something you would have to look up in the instruction manual.
The most preferred or commonly used decoders are n-to-m decoders, where m<= 2^n. An n-to-m decoder has n inputs and m outputs and is also referred to as an n * m decoder. The following image shows a 3-to-8 line decoder with three input variables which are decoded into eight output, each output representing one of the combinations of the three
