  • Patent number: 12346264
    Abstract: Performing instruction fetch pipeline synchronization (IFPS) in processor-based devices is disclosed herein. In some exemplary aspects, a processor-based device provides multiple processors including a remote processor. The remote processor receives, from an issuing processor, a translation lookaside buffer (TLB) invalidation (TLBI) request indicating a request to invalidate an address translation, and subsequently receives an IFPS request from the issuing processor. The remote processor determines that any previously received TLBI requests including the most recent TLBI request have completed. Upon receiving the IFPS request, the remote processor determines that all instructions within a fetch pipeline portion that were potentially fetched using address translations older than the IFPS request have proceeded from the fetch pipeline portion of an instruction processing circuit to an execution pipeline portion of the instruction processing circuit.

  • Publication number: 20250103506
    Abstract: In processors that include a memory tagging extension (MTE), before reading data from or writing data into a memory address, tag bits associated with the memory address are read from the memory and compared to tag bits in the instruction target address. This delays memory write instructions that would not otherwise have to perform a read from the memory circuit before executing the write operation (e.g., full cache line writes), reducing processor performance. An exemplary processing circuit includes a toggleable MTE to provide access to a memory circuit in one of a first mode, in which a memory tagging extension is enabled, and a second mode, in which the MTE is disabled. The processing circuit includes an execution circuit to process a memory instruction and a load/store circuit that does not read the tag bits when MTE is disabled, thereby reducing execution time of the memory instruction.

  • Patent number: 12175243
    Abstract: Aspects disclosed include hardware micro-fused memory (e.g., load and store) operations. In one aspect, a hardware micro-fused memory operation is a single atomic memory operation performed using a plurality of data register operands, for example a load pair or store pair operation. The load pair or store pair operation is treated as two separate operations for purposes of renaming, but is scheduled as a single micro-operation having two data register operands. The load or store pair operation is then performed atomically.

  • Publication number: 20240376882
    Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

  • Publication number: 20240009007
    Abstract: A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.
