Abstract: A system includes a branch predictor and a processing circuit configured to perform a plurality of operations including storing a skip-over offset value in the branch predictor. The skip-over offset value defines a number of search addresses of the branch predictor to be skipped. The operations further include searching the branch predictor for a branch prediction. Responsive to finding the branch prediction, the searching of the branch predictor is re-indexed based on the skip-over offset value associated with the branch prediction.

Abstract: A computer system includes a branch detection module and a branch predictor module. The branch detection module determines that a first program branch is a possible call branch having a next sequential instruction address (NSIA), and determines that a first routine branch is a possible return capable branch having the first routine instruction address that is a detected as being offset. The branch predictor module determines that a second program branch is a possible call branch having a next sequential instruction address (NSIA), and determines that a second routine branch is a predicted return branch having a predicted target instruction address based on the NSIA of the second program branch and the predicted offset.

Abstract: Log synchronization among discrete devices in a computer system includes, periodically at a predefined interval: sending, by a host to each of a plurality of discrete devices in the computer system, a synchronization tag, wherein each of the discrete devices, responsive to receiving the synchronization tag from the host, is configured to record the synchronization tag in a log entry; and recording, by the host, the synchronization tag in a log entry.

Abstract: A NAND flash memory device detects the occurrence of Cell Voltage Distribution Disruption Events (CVDDEs), such as a Partial Block Program (PBP) and Program-Read-Immediate (PM), and provides a way to dynamically adjust read voltage to account for CVDDEs. A read command includes extended addressing bits that are used when a CVDDE has occurred to access registers that indicate an adjustment to read voltage that is needed to accommodate the CVDDE. The read voltage is then dynamically adjusted to accommodate the CVDDE. When the CVDDE is no longer an issue, the read voltage is adjusted to its previous value before the CVDDE.

Abstract: The present invention provides a system and method for controlling data entries in a hierarchical buffer system. The system includes an integrated circuit device with a memory core, a high speed upstream data bus, and a plurality of 1st tier buffers that receive data from the memory. The system further includes a 2nd tier transfer buffer spanning a plurality of asynchronous timing domains that delivers the data onto the upstream data bus to minimize gaps in a data transfer. The method includes managing the buffers to allow data to flow from a plurality of 1st tier buffers through a 2nd tier transfer buffer, and delivering the data onto a high speed data bus with pre-determined timing in a manner which minimizes latency to the extent that the returning read data beats are always transmitted contiguously with no intervening gaps.

Abstract: Mechanisms are provided for efficient storage of meta-bits within a system memory. The mechanisms combine an L/G bit and an SUE bit to form meta-bits. The mechanisms then determine the local/global state of a cache line on the first cycle of data. The mechanisms forward the data to the requesting cache, and the requesting cache may reissue the request globally based on the local/global state of the cache line. The mechanisms then determine the special uncorrectable error state of the cache line on the second or subsequent cycle of data. The mechanisms perform error processing regardless of whether the request was reissued globally.
