Consider a $32$- bit processor which supports $70$ instructions. Each instruction is $32$ bit long and has $4$ fields namely opcode, two register identifiers and an immediate operand of unsigned integer type. Maximum value of the immediate operand that can be supported by the processor is $8191$. How many registers the processor has? $32$ $64$ $128$ $16$

A digital computer has memory unit with $24$ bits word.The instruction set consists of $150$ different operations. All instructions have an operation code part and an address part. Each instruction is stored in one word of memory. $Q1$ How many bits are needed for the OP-CODE and how many bit are left for the ... $2^{16}, 2^{24}$ $2^{16},2^{24}-1$ $\textrm{None of these}$

If someone mentioned "index value" in indexed addressing mode then which value is it referring; the value of index register or the constant value? It should be value of index register, isn't it? But from the given snippet it seems that they are referring constant value Please clarify Thank You
