US 2025/0028627 A1 · ADAPTIVE HARDWARE TRACING

Abstract

An adaptive hardware trace circuit is presented. The adaptive hardware trace circuit may include one or more trace circuits, a trace port funnel circuit, a trace FIFO buffer, and an adaptation logic circuit. Each trace circuit may be coupled to a processor core and configured to monitor and encode trace data generated by a processor core. The trace buffer may be configured to store the trace data generated by the processor cores. The adaptation circuit may be configured to receive, from a user, one or more buffer capacity thresholds and a priority level assigned to each trace. The adaptation circuit may map ranges of trace buffer capacities to corresponding sets of actions. The adaptation circuit may detect a buffer capacity to determine a set of one or more actions associated with the buffer capacity and execute the set of one or more actions.

Dependent claims

A circuit, comprising:

one or more processor cores that generates trace data;
and
an adaptive trace circuit coupled to the one or more processor cores, the adaptive trace circuit comprising:
one or more trace circuits, each trace circuit coupled to a corresponding processor core of the one or more processor cores, wherein each trace circuit captures the trace data generated by the corresponding processor core;
a trace port funnel circuit coupled to receive trace data from the one or more trace circuits, wherein the trace port funnel circuit combines the trace data into a single stream of trace data;
a trace buffer having a buffer capacity, wherein the trace buffer stores the single stream of trace data;
and
an adaptation circuit coupled to the trace buffer, wherein the adaptation circuit detects a capacity of the trace buffer, identifies one or more actions associated with the buffer capacity, and signals the one or more of trace circuits to execute the one or more actions.
