  • Method and apparatus for detecting pipeline address conflict using parallel compares of multiple real addresses
    Patent number: 6963964
    Abstract: In a computer processor, multiple partially translated real addresses for a pipelined operation are compared with the real addresses of one or more other operations in the pipeline to detect an address conflict, without waiting for the address translation mechanism to fully translate the real address. Preferably, if a match is found, it is assumed that an address conflict exists, and the pipeline is stalled one or more cycles to maintain data integrity in the event of an actual address conflict. Preferably, the CPU has caches which are addressed using real addresses, and an N-way translation lookaside buffer (TLB) for determining the high-order portion of a real address. Each of the N real address portions in the TLB is compared with other operations in the pipeline, before determining which is the correct real address portion.

  • Positive flow valve
    Publication number: 20050222541
    Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip.

  • Zero delay data cache effective address generation
    Patent number: 6941421
    Abstract: A method and system for accessing a specified cache line using previously decoded base address offset bits, stored with a register file, which eliminate the need to perform a full address decode in the cache access path, and to replace the address generation adder multiple level logic with only one level of rotator/multiplexer logic. The decoded base register offset bits enable the direct selection of the specified cache line, thus negating the need for the addition and the decoding of the base register offset bits at each access to the cache memory. Other cache lines are accessed by rotating the decoded base address offset bits, resulting in a selection of another cache word line.

  • History-based carry predictor for data cache address generation
    Patent number: 6877069
    Abstract: An address translation logic and method for generating an instruction's operand address. The address generation logic includes an address generation circuit having adders that perform partial sum additions of the instruction operand's base register value with a displacement value in the instruction. The address generation logic also includes a carry prediction history block associated with the instruction that provides predicted carry-in values to the adders during the partial sum addition operation. In a related embodiment, the carry prediction history block that, in an advantageous embodiment, is appended to the instruction includes a predicted row access select (RAS) carry-in value, a predicted column access select (CAS) carry-in value and a confirmation flag that indicates whether the previous carry-in predictions for the previous predicted RAS and CAS carry-in values for the instruction were correct.

  • Carry generation in address calculation
    Patent number: 6868489
    Abstract: Embodiments are provided in which the generation of a carry of a sum of two numbers can be implemented by adding only some most significant bits of the two numbers and assuming that the sum of the remaining bits do not generate a carry. Other embodiments are also provided in which the generation of the carry of a sum of the two numbers can be implemented using carry look-ahead techniques wherein generate and propagate terms are generated. By combining the product terms of the carry function and combining pairs of propagate or generate terms, the generation of the carry of the sum of the two numbers can be implemented in an And-Or-Inverter function less complex than that of prior art. Still other embodiments are provided in which one operand of a carry generation circuit comes from a fixed source and the other operand is selected from several forwarding sources.
