An apparatus, method, and system are described herein for providing programmable control of performance / event counters. An event counter is programmable to track different events, as well as to be checkpointed when speculative code regions are encountered. So when a speculative code region is aborted, the event counter is able to be restored to it pre-speculation value. Moreover, the difference between a cumulative event count of committed and uncommitted execution and the committed execution, represents an event count / contribution for uncommitted execution. From information on the uncommitted execution, hardware / software may be tuned to enhance future execution to avoid wasted execution cycles.

Multi-threaded, transactional memory systems may allow concurrent execution of critical sections as speculative transactions. These transactions may abort due to contention among threads. Hardware feedback mechanisms may detect information about aborts and provide that information to software, hardware, or hybrid software / hardware contention management mechanisms. For example, they may detect occurrences of transactional aborts or conditions that may result in transactional aborts, and may update local readable registers or other storage entities (e.g., performance counters) with relevant contention information. This information may include identifying data (e.g., information outlining abort relationships between the processor and other specific physical or logical processors) and / or tallied data (e.g., values of event counters reflecting the number of aborted attempts by the current thread or the resources consumed by those attempts). This contention information may be accessible by contention management mechanisms to inform contention management decisions (e.g. whether to revert transactions to mutual exclusion, delay retries, etc.).

Systems and methods implement queues that perform write operations in a re-circulating sequential manner. The nature of the queue systems of the present invention allow writes to the queue to occur independently of read operations therefrom. A current event counter is updated by the queue logic to keep track of a count value that corresponds to the total number of data events written to the queue. Preferably, the current event counter is capable of counting an amount greater than the total number of addressable storage locations of the queue. A write pointer may be derived from the count value stored in the event counter from which a select addressable storage location of the queue can be determined for queuing each new data event. Read operations from the queue may be performed according to any prescribed manner, including random access thereto. Moreover, read operations can be performed in a first manner when no overflow is detected, and in a second manner in response to overflow.

A collection of techniques allow for the detection of covert malware that attempts to hide its existence on a system by leveraging both trusted hardware event counters and the particular memory addresses (as well as the sequences of such addresses) of the instructions that are generating the suspected malicious activity. By monitoring the address distribution's specific patterns over time, one can build a behavioral model (i.e., “fingerprint”) of a particular process—and later attempt to match suspected malicious processes to the stored behavioral models. Whenever the actual measured behavior of a suspected malicious process fails to match said stored behavioral models, the system or system administrator may attempt to perform rehabilitative actions on the computer system to locate and remove the malware hiding on the system.

Methods for estimating data-dependent jitter (DDJ) from measured samples of a transmitted data signal include a first exemplary step of obtaining a plurality of measurements (e.g., time tags and event counts for selected pulse widths in the data signal). Such measurements may be obtained at predetermined intervals within a transmitted signal or may be obtained at randomly selected intervals, and should yield measurements for each data pulse in a repeating data pattern.

DDJ delta lines are then calculated for signal edges of each pulse width in the transmitted data pattern, from which peak-to-peak DDJ values and / or estimates of duty-cycle-distortion (DCD) can be determined.
