Abstract: An apparatus is provided for improving the use of multiple-issue operations in a data processor. A variable-issue operation can be recognised is being either a single-issue operation or a multiple-issue operation in dependence on the state of the program at runtime. If a variable-issue operation can be scheduled as a multiple-issue operation, then other operations can be scheduled for performance in the same cycle, when they would have otherwise had to be scheduled for a later cycle. As such, more operations can be performed in fewer cycles thus improving code density and improving data processing performance.
