Abstract: A shared counter resource, such as a register, is disclosed in the hardware, where the register representing how much free space there is in the command queue is accessible to one or more processing elements. When a processing element reads the “reservation” register, the hardware automatically decrements the available free space by a preconfigured amount (e.g., 1) and returns the value of the free space immediately prior to the read/reservation. If the read returns 0 (or a number less than the preconfigured amount), there was insufficient free space to satisfy the request. In the event there was insufficient space to satisfy the request the reservation register may be configured to reserve however much space was available or to not reserve any space at all. Any number of processing elements may read these registers and various scenarios are described where the input and output queues are accessible via various processing elements.

Abstract: Methods, apparatuses, systems, and devices are described for determining use of areas of a disk drive. In one method, a score of an area node of the disk drive may be increased each time the area node is accessed during a time interval of a series of time intervals. When each time interval elapses, each existing score of the area nodes (e.g., scores of area nodes that have non-zero scores) may be decreased. Further, after being decreased, each existing score may be saved. In such a manner, a time series analysis of data accesses may be implemented. The increases in score may account for the number of accesses during a given interval, and the decreases in score may account for time passage (e.g., time-weighting the scores). Thus, more frequent accesses and more recent accesses result in higher accumulated scores for the corresponding area nodes.

Abstract: Embodiments include systems and methods for providing robust clock-skew-tolerant memory updating in high-speed memory circuits. For example, in each memory update interval, update of a pre-memory with un-validated update data begins when a potential match is detected between a tag memory and a key (whether according to a base clock or a delayed clock); but the update data is not considered valid (nor is it written out as such) until a determination is made according to the delayed clock. The un-validated update data can be written out from the pre-memory as validated update data for the memory update interval upon detection of a data valid indication generated from the delayed hit indication.
