Abstract
Fine-grained enablement at sub-function granularity. An instruction encapsulates different sub-functions of a function, in which the sub-functions use different sets of registers of a composite register file, and therefore, different sets of functional units. At least one operand of the instruction specifies which set of registers, and therefore, which set of functional units, is to be used in performing the sub-function. The instruction can perform various functions (e.g., move, load, etc.) and a sub-function of the function specifies the type of function (e.g., move-floating point; move-vector; etc.).
