  • Patent number: 9201654
    Abstract: Disclosed are a processor and a processing method incorporating an instruction pipeline with direction prediction (i.e., taken or not taken) for conditional branch instructions. In the embodiments, reading of a branch instruction history table (BHT) and a branch instruction target address cache (BTAC) for branch direction prediction occurs in parallel with the current instruction fetch in order to minimize delay in the next instruction fetch. Additionally, direction prediction is performed in the very next clock cycle based either on an initial direction prediction for the specific instruction, as stored in the BHT, or, if applicable, on a prior entry for the specific instruction in the BTAC. An override bit associated with each entry in the BTAC is the determining factor for whether or the BTAC or BHT is controlling. Override bits in the BTAC can be pre-established based on the branch instruction type in order to ensure prediction accuracy.

  • Patent number: 8793433
    Abstract: A processor contains multiple levels of registers having different access latency. A relatively smaller set of registers is contained in a relatively faster higher level register bank, and a larger, more complete set of the registers is contained in a relatively slower lower level register bank. Physically, the higher level register bank is placed closer to functional logic which receives inputs from the registers. Selection logic enables selecting output of either register bank for input to processor execution logic. Preferably, the lower level bank includes a complete set of all processor registers, and the higher level bank includes a smaller subset of the registers, duplicating information in the lower level bank. The higher level bank is preferably accessible in a single clock cycle.

  • Patent number: 8364933
    Abstract: A computer implemented method searches a unified translation lookaside buffer. Responsive to a request to access the unified translation lookaside buffer, a first order code within a first entry of a search priority configuration register is identified. A unified translation lookaside buffer is then searched according to the first order code for a hashed page entry. If the hashed page entry is not found when searching a unified translation lookaside buffer according to the first order code, a second order code is identified within a second entry of the search priority configuration register. The unified translation lookaside buffer is then searched according to the second order code for the hashed page entry.

  • Patent number: 7937568
    Abstract: A method, system and processor for increasing the instruction throughput in a processor executing longer latency instructions within the instruction pipeline. Logic associated with specific stages of the execution pipeline, responsible for executing the particular type of instructions, determines when at least a threshold number of the particular-type instructions is scheduled to be executed. The logic then automatically changes an execution cycle frequency of the specific pipeline stages from a first cycle frequency to a second, pre-established higher cycle frequency, which enables more efficient execution and higher execution throughput of the particular-type instructions. The cycle frequency of only the one or more functional stages are switched to the higher cycle frequency independent of the cycle frequency of the other functional stages in the processor pipeline.

  • Patent number: 7865786
    Abstract: A system for at-functional-clock-speed continuous scan array built-in self testing (ABIST) of multiport memory is disclosed. During ABIST testing, functional addressing latches from a first port are used as shadow latches for a second port's addressing latches. The arrangement reduces the amount of test-only hardware on a chip and reduces the need to write complex testing software. Higher level functions may be inserted between the shadow latches and the addressing latches to automatically provide functions such as inversions.
