A variable speed bus has its frequency adjusted based upon bandwidth requirements of active units coupled to a variable speed bus. As units coupled to the bus are stopped, bandwidth requirements are lowered and the bus frequency is reduced in response to the lowered bandwidth requirements. An arbiter selects an appropriate arbitration configuration based on which units are active and which are stopped. The arbitration configuration is adjusted to ensure that the bandwidth requirements of the active units are sustained despite the reduced clock frequency...
What is claimed is: 1. An apparatus, comprising: a variable speed bus; a first unit coupled to the variable speed bus; a second unit coupled to the variable speed bus; and an arbitration and bus clock control unit to adjust the variable speed bus frequency depending on the bandwidth requirements of the first and second units, the arbitration and bus clock control unit to monitor which of the first and second units are active and to select an appropriate arbitration configuration depending on which of the first and second units are active, wherein the ar...
