Abstract
Embodiments of the present invention relate to instruction fetching in data processing systems. One aspect involves a data processor ( ) to execute instructions and to fetch instructions from a memory ( ) according to a fetch size. This data processor ( ) comprises a first input ( ) to receive instructions, control logic ( ) to decode the instructions, and an instruction pipeline ( ) coupled to the first input ( ) and the control logic ( ). The instruction pipeline ( ) is responsive to a first signal ( ) to set the fetch size to one of a first size and a second size. The data processor ( ) therefore allows an instruction fetch policy to be altered based on the characteristics of an accessed device in order to achieve improved performance.
