Problems solved by technology

However, these paths are specific to a particular CPU, bus, or subsystem and cannot be used to observe the same CPU, bus, or subsystem with different trace unit setups for different output destination on-chip trace buffers and off-chip trace interfaces
[0010] Therefore, the current architecture of conventional trace units is insufficient to support the observation of long history traces, and conventional trace systems cannot be easily expanded due to overhead wiring and limited trace memory bandwidth

Embodiment Construction

[0022] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustrations specific embodiments in which the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural or other modifications may be made without departing from the scope of the present disclosure. Accordingly, the following detailed description should not be read in a limiting sense, and the scope of the present disclosure is defined by the appended claims.

[0023] Tracing the flow is useful for software debugging of an application in order to determine what kind of events have occurred before a particular software problem arises. Tracing flows is also useful for analyzing the performance of task-oriented embedded and non-embedded applications executing on various software / hardware platforms. For example, task-oriented software programs may be executed by processors applica...

Abstract

The present disclosure relates to methods and systems for tracking solutions in computer processing systems. More specifically, the present disclosure relates to methods and systems for multi-tier tracing architectures. A method for separating raw trace data includes receiving raw trace data from one or more CPUs and / or buses in a system, separating the raw trace data into high bandwidth trace information (HBTI) and low bandwidth trace information ( LBTI), record HBTI on the on-chip trace buffer until a specific event is triggered, and provide LBTI through the off-chip trace interface in parallel. In one embodiment, raw tracking data is provided to a separate HBTI tracking unit and a separate LBTI. The HBTI tracking unit processes HBTIs and generates HBTI messages, and the LBTI tracking unit processes LBTIs and generates LBTI messages.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 746,390, filed December 27, 2012, entitled "Multi-Tier Trace," the contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to methods and systems for tracking solutions in computer processing systems. More specifically, the present disclosure relates to methods and systems for a multi-layer tracing architecture for observing and tracing one or more computer processing units in a real-time system. Background technique [0004] For software debugging or performance analysis, tracing the flow enables reconstruction of the flow of the monitored program and is therefore useful for determining what type of events occur before a particular software problem arises. Tracing systems or architectures are used to observe the behavior of real-time control systems such as automotive electronic ...
