Identifying causes of anomalies observed in an integrated circuit chip

A method of identifying a cause of an anomalous feature measured from system circuitry on an integrated circuit (IC) chip, the IC chip comprising the system circuitry and monitoring circuitry for monitoring the system circuitry by measuring features of the system circuitry in each window of a series of windows, the method comprising: (i) from a set of windows prior to the anomalous window comprising the anomalous feature, identifying a candidate window set in which to search for the cause of the anomalous feature; (ii) for each of the measured features of the system circuitry: (a) calculating a first feature probability distribution of that measured feature for the candidate window set; (b) calculating a second feature probability distribution of that measured feature for window(s) not in the candidate window set; (c) comparing the first and second feature probability distributions; and (d) identifying that measured feature in the timeframe of the candidate window set as a cause of the anomalous feature if the first and second feature probability distributions differ by more than a threshold value; (iii) iterating steps (i) and (ii) for further candidate window sets from the set of windows prior to the anomalous window; and (iv) outputting a signal indicating those measured feature(s) of step (ii)(d) identified as a cause of the anomalous feature.

PERFORMANCE THROTTLING MODULE

Provided is a method for regulating, via a hardware performance throttling block (PTB) of a memory module, the performance of a memory system in response to read and write requests from a processing system which hosts the memory system. The host system sends memory service requests to the memory system in the form of memory read requests and memory write requests. The host system may also send requests to throttle, that is, to limit the responses of the memory system in response to memory requests; the host system may also send to the memory system various parameters indicative of current memory usage. In response to the throttling request, the PTB of the memory module either stops any reception of memory requests, or limits (throttles) the number of memory requests (either read requests, write requests, or both) for a specified number of clock/command cycles. The PTB also determines when full, un-throttled performance may be resumed.
