Abstract: A data loading device for loading data into computer processor units from a data source, the device comprising at least a first connector for connecting to the data source and provided with a PHY component, and a plurality of second connectors for connecting to the computer processor units and each provided with a respective PHY component, the first connector being connected to the second connectors by a first selector module in order to define a single down channel so as to transmit data from the first connector to each of the second connectors individually, and by a second selector module for defining a single up channel so as to transmit data in the opposite direction, the selector modules being arranged to be capable of connecting only one of the second connectors at a time to the first connector and the device including a control unit for controlling the selector modules to select which second connector to connect to the first connector.

Abstract: A transducer for an inductive displacement sensor includes a secondary winding of 2N turns of alternating directions extending in a zone of length Dtot, the winding including: a first coiled conductive section forming N half-turns, extending between a first end of the winding, situated at the midpoint of the length Dtot, and a first point of the winding, situated at one end of the length Dtot; a second section forming N half-turns, extending between the first point and a second intermediate point situated at the midpoint of the length Dtot; a third section forming N half-turns, extending between the second point and a third intermediate point situated at a second end of the length Dtot; and a fourth section forming N half-turns, extending between the third point and a second end of the winding situated at the midpoint of the length Dtot.

Abstract: A data handling system is provided in which a circular queue formed in paged memory is used to buffer the transfer of data items between a producer entity and a consumer entity. The producer entity maintains a tail pointer into the queue to indicate the storage location next to be written to; similarly, the consumer entity maintains a head pointer to indicate the storage location next to be read. Since the head and tail pointers may point to different memory pages and these may not have been assigned in a contiguous block to the circular queue, the derivation of queue status information using the head and tail pointers is complex. To simplify this task, the producer and consumer entities maintain producer and consumer indexes for the next write and read positions based on a logical view of the queue as a circular continuum of storage locations.

Abstract: In order to schedule the transmission of cells of guaranteed-bandwidth virtual channels, a circular list is provided having a predetermined number of entry slots and each channel with cells to send has a corresponding identifier VCN placed in a respective slot in the list, only one VCN being allowed per slot. The list is advanced through slot by slot and each VCN encountered is processed to cause the transmission of a cell for the corresponding virtual channel. The list is also updated for each slot advanced past by freeing that slot and inserting back into the list any VCN that occupied the slot if that VCN relates to a virtual channel with another cell to transmit. This insertion is effected at an offset from the slot previously occupied by the VCN, dependent on a transmission rate indicator (SRP, PRP) of the virtual channel concerned.
