A cache way replacement technique to identify and replace a least-recently used cache way. A cache way replacement technique in which a least-recently used cache way is identified and replaced, such that the replacement of cache ways over time is substantially evenly distributed among a set of cache ways in a cache memory. A least-recently used cache way is identified in a cache memory having a non-binary number of cache ways.

Cache way replacement technique

A motherboard/daughterboard assembly is configured to permit upgrading of a system to a microprocessor requiring different clock signals. The motherboard includes a clock generator mounted on the motherboard with a control input terminal and an output terminal. The clock generator delivers a first and second clock signal on the output terminal in response to receiving a first and second signal on the control input terminal, respectively. A first electrical connector is mounted on the motherboard and has a first terminal. The first terminal is coupled to the control input terminal of the clock generator. The daughterboard has a second electrical connector mounted thereon, and a first terminal. The second electrical connector is mateable with the first electrical connector to electrically engage the first terminals of the first and second electrical connectors. The first terminal of the second electrical connector is adapted to be connected to one of a first and second voltage supply to generate one of the first and second signals on the control input terminal of the clock generator in response to the first and second electrical connectors being mated together.

Method and apparatus for automatically selecting clock voltage levels

A power supply supplies power from a bus at a hub to a peripheral over a bus which plugs into a connector at the hub, the connector having a plurality of contacts, including at least two power contacts the power supply. When the bus is plugged into the connector, a mated contact is provided in the connector at the hub. When a mating connector on the bus is plugged in, one of the plurality of contacts is shorted to the mated contact. The sensed shorting at the mated contact is used to control the ramping of current on the power lines of connector.
