Abstract
An apparatus comprises: processing circuitry, an instruction decoder, and registers. In response to an overlapped-immediate/register-field-specifying (OIRFS) instruction comprising an opcode field specifying an OIRFS-indicating opcode value, and an overlapped immediate/register field specifying an immediate value and a register specifier, the instruction decoder controls the processing circuitry to use a selected register of the plurality of registers corresponding to the register specifier as a source register or destination register when performing a processing operation depending on the immediate value. The overlapped immediate/register field includes at least one shared bit decoded as part of the immediate value for at least one encoding of the OIRFS instruction and decoded as part of the register specifier for at least one encoding of the OIRFS instruction.
