Instruction decoder takes bits stored in the instruction register and decodes it and tells to CPU what it need to do for it and enable the components for the operation.
Simply, instruction decoder is like a dictionary. It tells the meaning of the instruction.

What is the role of decoder of CPU?
The instruction decoder is the part of the CPU that converts the bits stored in the instruction register into control signals need to control other parts of the processor. In CPUs that use microcode, the decoder converts microinstructions into the control signals.
What controls the operation of each and every component of the computer system?

Why instruction decoder of 8085A is 8 bit?
Decoder is the system which is used to decode or translate the code and make the message again readable. Both encoder and decoder are used where encoding language is applied. For example, if a word TRANSLATION is encoded then it can be written in various forms like NOITALSNART.

What is the difference between Instructions decode and register fetch?
Instruction register is use to store the next instruction to be executed.Instruction decoder is use to decode the instruction come from the memory and tell the CPU what is instruction really are. (CPU interpret instruction is different from the data store in the memory . A good example is , memory can store hexadecimal, but device only can read binary data.) without decoder the device cannot indicate or recognize the data )Distinction"memory can store hexadecimal, but device only can read binary data" This is an improperly worded, misleading statement. The difference between binary and hexadecimal is purely interpretive. Reading hexadecimal is a function of dividing the bits into groups of 4 and assigning a unique symbol to the pattern; 0-9 + A-F. This is only translating from one numbering system to another. The memory isn't specifically able to store hexadecimal as opposed to binary; it stores a BYTE as a group of EIGHT BITS no matter what. So even if the hardware is designed to move 64 bits at a time, grouping the bits into nibbles of four bits is how we interpret the bit pattern in hexadecimal.Another Answer
Where can we use decoder?
you can use the decoder in spy island. if you see some mysterious people, (normally in black) talk to them and they may give you a message.
What does the terms superscalar mean?
The use of many different arithmetic/logic pipelines in parallel along with a multiple instruction dispatch instruction decoder unit to allow simultaneous execution of several scaler instructions in every clock cycle. This usually requires a score-boarding unit and a mechanism for register aliasing to keep the data flow coordinated with the instruction flow.

How do you use the decoder in spy island poptropica?
you use the decoder to depict spy messages. you line up both letters so that the red is lined up with the green text. the red text is the outer ring. then you look at the red text and look under it to match the green text. then you type it on the lower section of the note pad. that is how you use a decoder on spy island
