Abstract: A processor (100) includes a preload queue (160) for storing a plurality of preload entries. Each preload entry is associated with a preload instruction and includes the address and byte count defined by the respective preload and an identifier associated with the respective preload. A comparison unit (170) associated with the preload queue (160) identifies each conflicting preload entry, that is, each preload entry associated with a preload instruction that conflicts with an older store instruction. The oldest preload instruction associated with one of the conflicting preload entries represents a target preload. The processor (100) may flush this target preload along with all instructions executed after the target preload in order to correct for the conflict between the target preload and store instruction.

Abstract: A mechanism and method for a store data queue are implemented. Address translation operations for store instructions in a data processor are decoupled from data operations by initiating address translation before source data operands are available. A store data queue snoops the finish buses of execution units for the source operand. A data entry in the data queue that is allocated at dispatch of the store instruction snoops for the source operand required by its corresponding instruction. The data operand is then communicated to a memory device in instruction order thereby simplifying the detection of conflicting stores.

Abstract: A torque converter has a lip seal abutting the torque converter impeller control pump drive hub. The drive hub is rotatably supported in a transmission housing. Oil from the drive hub side of the bushing passes through the bushing into a chamber sealed from atmosphere by the lip seal. The lip seal has a component rotatably sealing on a diameter greater than the drive hub diameter. The bushing, in one embodiment, has a control passage for exhausting a portion of the oil from the control pump side prior to reaching the chamber.

Abstract: An improved printer is provided which includes a print engine control program that minimizes the power consumption of the paper-handling devices to allow for a smaller DC power supply. Some of the paper-handling devices are input paper trays, output paper stackers, and a duplexer, which all preferably contain a microcontroller and an individual electric motor drive. The base printer also contains a microcontroller in the print engine that controls the printer's mechanisms and various subassemblies that are used in the laser electrophotographic printing process. To maintain control of the entire paper path, the print engine sends commands to the paper-handling devices, and these devices send responses to these commands. Most of the printer's paper-handling devices receive their electrical power entirely from the base printer, which is supplied as a DC voltage. The print engine avoids the concurrent running of subsystems in cases where the functionality of the printer is not compromised.
