    Abstract: The present invention relates generally to microprocessor or microcontroller architecture, and particularly to an architecture structured to handle unaligned memory references. A method is disclosed for loading unaligned data stored in several memory locations, including a step of loading a first part of the unaligned data into a first storage location and rotating the first part from a first position to a second position in the first memory location. Next a second part of the unaligned data is loaded into a second storage location and rotated from one position to another position. Then the first storage location is combined with the second storage location using a logical operation into a result storage location. The storage locations may be, for example, 64-bit registers. The logical operation may be a bit-wise OR operation. The method may optionally include, performing masking, zero-extending and/or sign extending operations on the first storage location, when the first part of the unaligned data is in the second position of the first storage location.

    Abstract: Methods and an apparatus for storing information in a processing device with flexible security are disclosed. In one embodiment, an apparatus processes back-to-back write and read operations without stalling the processor. A cache memory subsystem buffers write operations between a central processing unit (CPU) and the cache memory subsystem. Included in the cache memory subsystem are a tag memory, a data memory and a store buffer. The store buffer is coupled to both the data memory and the tag memory. Additionally, the store buffer stores a write operation.

    Abstract: An apparatus and method for providing an accurately regulated flow of liquid medium to a device mounted in or on a rotor of a centrifuge, comprises a scoop on the rotor having a mouth opening forwards in the direction of rotation, with a duct connecting the mouth to the device; the liquid medium being projected as a jet into the path of the rotating scoop so that the mouth chops out a mid-portion of the jet during each revolution, and feeds it to the device. Rotation rates are high, typically 50,000 rpm for devices like liquid flow density balances for mass detection, but may be less and/or variable with SFFF devices.

    Abstract: A method for packing a chromatography column having an inlet port at one end and an outlet port at the other, comprises feeding a slurry or smoke of particulate bed material in a carrier fluid and applying a predetermined pressure to the bed material while allowing the carrier fluid to escape, wherein both the inlet and outlet ports are protected by porous bed-retaining means positioned apart to provide a space for the bed between them, at least a final portion of the slurry or smoke being fed through a filler tube into the space for the bed until the space is full and the bed extends back into the filler tube, predetermined pressure to the bed being applied via the slurry or smoke in the filler tube, and the filler tube then sealed being against relaxation of the bed pressure.
