Abstract
A floating point unit is provided with a register bank comprising 32 registers that may be used as either vector registers of scalar registers. A data processing instruction includes at least one register specifying field pointing to a register containing a data value to be used in that operation. An increase in the instruction bit space available to encode more opcodes or to allow for more registers is provided by encoding whether a register is to be treated as a vector or a scalar within the register field itself. Further, the register field for one register of the instruction may encode whether another register is a vector or a scalar. The registers can be initially accessed using the values within the register fields of the instruction independently of the opcode allowing for easier decode.
