摘要:
A motor that delivers high force linear motion or high torque rotary motion to a moving element. The motor may include a driving brake, a driver, a holding brake and a flexible moving element. Operation of the motor may involve activating the holding brake, activating the driver to flex the moving element, activating the holding brake to maintain the position of a portion of the moving element, releasing the driving brake, and restoring the moving element to an unflexed position. The elements are arranged to provide linear motion, belt-driven rotary motion, or directly-coupled rotary motion using brakes and drivers arranged in linear or circular fashion. Drivers may be linear or rotary actuators or motors based on electrostatic, piezoelectric, magnetic, or electrostrictive properties. The brakes may be applied through electrostatic forces, magnetic forces, or mechanical gears engaged with a linear or rotary driving mechanism.

Adaptive sets of lanes are configured between routers in a system area network. Source nodes determine whether packets may be adaptively routed between the lanes by encoding adaptive control bits in the packet header. The adaptive control bits also facilitate the flushing of all lanes of the adaptive set. Adaptive sets may also be used in uplinks between levels of a fat tree.

A processing system includes multiple processor units and multiple input/output elements communicatively interconnected by a system area network having a plurality of multi-ported router elements. Communication between the system elements uses message packets that contain, among other things, destination information that identifies the intended recipient of the message packet. That destination information is used, at least in part, for routing message packets from a its source to its intended destination. Deadlocks are eliminated by providing each router with information as to which ports cannot be used for re-transmission of a message packet, depending upon which port is receiving that message packet.
摘要:
First and second banks of control stores are used to store microinstructions. Each bank contains three control stores: A horizontal control store, a vertical control store, and a jump control store. The horizontal control store contains the rank four microcode; the vertical control store contains the rank three microcode; and the jump control store contains the same microcode as the vertical control store but is used on conditional jump microoperations. This allows simultaneous accessing of different microinstructions using a single address incrementer. The control store banks are accessed in an overlapping manner so that upon each clock cycle one bank is loading the rank 3 and rank 4 registers. The sequencer according to the present invention includes a return address stack for returning from subroutine calls and trap routines. When processing trap routines, the return address stack stores two microinstruction addresses to allow processing of a previously encountered jump or call operation that may have been aborted when the trap routine was entered.
摘要:
A system for issuing a family of instructions during a single clock includes a decoder for decoding the family of instructions and logic, responsive to the decode result, for determining whether resource conflicts would occur if the family were issued during one clock. If no resource conflicts occur, an execution unit executes the family regardless of whether dependencies among the instructions in the family exist.

A communication system transmitting AMI encoded data forces a latent error to occur within a predetermined time duration from an event which generated the latent error. Bit values of original data are selectively inverted to prevent a long sequence of zeros from being transmitted.

摘要:
A computer architecture has a plurality of processing cells interconnected to perform programming tasks. Each cell contains both memory and processing elements. Memory packets contain an instruction, a data element, and a pointer to another memory packet. Tasks are executed by following a linked list of memory packets. Transmission packets communicate instructions and register values along the linked list. A plurality of computer processes may be executed simultaneously.
摘要:
A mechanism for handling exceptions in a processor system that issues a family of more than one instruction during a single clock that utilizes the exception handling procedures developed for single instructions. The mechanism detects an exception associated with one of the instructions in the family, inhibits the data writes for the instructions in the family, flushes the pipeline, and reissues the instruction singly. The exception handling procedure for the single instruction may then be utilized.
