This depends upon the language. In some languages the first bits may represent an address or label. Most assembly languages the first byte or two is an op code. Four bits is pretty small for an address--that is only half a byte. Four bits on the Intel 4004 chip represent a "word."

What factor help in deciding the length of instruction format?
the number of bits required to represent an instruction of a cpu is known as length of the instruction or known as instruction.
How many cents are in four bits?

What are four binary units?
If you are asking what is four (4) in the binary system, the answer is 100.
What is the four binary bits called?
its called a Nibble
How do you make 6 to 64 decoder using four 4 to 16 and one 2 to 4 decoder?
To create a 6 to 64 decoder using four 4 to 16 decoders and one 2 to 4 decoder, first, separate the 6 input bits into two groups: the upper 2 bits (let's call them A5 and A4) and the lower 4 bits (A3 to A0). Use the 2 to 4 decoder to decode the upper 2 bits, which will select one of the four 4 to 16 decoders. Then, connect the lower 4 bits to all four 4 to 16 decoders. The selected 4 to 16 decoder will activate one of its 16 outputs based on the lower 4 bits, resulting in a total of 64 outputs from the combination of the decoders.
How many bits are needed for the program counter and the instruction register?
24 bits are needed for the program counter. Assuming the instructions are 32 bits, then 32 bits are needed for the instruction register.
The number of bits processed in a single instruction is known as?
8 Bits
What factor help in deciding the length of instruction format?
the number of bits required to represent an instruction of a cpu is known as length of the instruction or known as instruction.
What is 3 byte instruction in microprocessor?
A two-byte instruction gives the specific function instruction in two bytes, or two words. The first specifies the opcode, which tells the microprocessor what operation will occur. The second specifies the operand, or the data that the operation is done on.
What is the use of instruction decoder?
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.
How do you write object code for format 2 instruction in sic xe machine?
To write object code for a format 2 instruction in the SIC/XE machine, you need to identify the opcode for the instruction and the registers involved. The object code consists of the 8-bit opcode followed by the 4-bit binary representation of the two registers. The format is typically structured as follows: the first 8 bits for the opcode, the next 4 bits for the first register, and the last 4 bits for the second register. Finally, you concatenate these binary values to produce the final object code.
What are 4 bits?
A group of four bits is known as a nibble.
How many bytes make up a nibble?
One nibble, or nybble, is equal to four bits.
Which logic instruction would you use to reverse the state of the bits in a word?
To reverse the state of the bits in a word, you would use the bitwise NOT instruction, often represented as ~ in many programming languages or as NOT in assembly language. This instruction flips each bit in the word, turning 0s into 1s and 1s into 0s. In a typical scenario, applying this instruction to a binary word effectively reverses its state.
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
When ANI F instruction is used in microprocessor?
The ANI F instruction causes the assembler to look in the symbol table for the symbol F, and to build an instruction that ANDs immediate that value with the accumulator. If you meant to say ANI 0FH, that means to clear the high 4 order bits of the accumulator and to retain the low 4 order bits.
