− | Because the immediate value is packed into the instruction itself certain [[ISA]]s have a restricted range of values that can be used as an immediate value. For example in [[MIPS32]], an immediate value is limited to 16-bits. On some more complex architectures such as [[ARM]], some instructions may accept a 16-bit value, others might accepted a smaller range with a the ability to rotate the bits as desired (see | + | Because the immediate value is packed into the instruction itself certain [[ISA]]s have a restricted range of values that can be used as an immediate value.
