Embodiment Construction

[0027] The disclosed subject matter pertaining to a non-intrusive thread-selective debugging method and system for a multi-threaded digital signal processor has application to any type of multi-threaded processing for which the benefits presented herein may benefit. One such application occurs in telecommunications, and in particular in wireless handsets that employ one or more digital signal processing circuits. To explain how this wireless handset can be used, figure 1 A simplified block diagram of a communication system 10 that can implement the presented embodiments of the disclosed interrupt handling method and system is provided. At transmitter unit 12, data is sent from data source 14, typically in blocks, to transmit (TX) data processor 16, which formats, encodes, and processes the data to produce one or more analog signal. The analog signal is then provided to a transmitter (TMTR) 18, which modulates, filters, amplifies, and upconverts the baseband signal to produce...

Abstract

The present invention discloses techniques for the design and use of a digital signal processor, including (but not limited to) for processing transmissions in a communications (e.g., CDMA) system. The method and system improve software instruction debugging operations by capturing real-time information relating to software execution flow and include and instructions and circuitry for operating a core processor process within a core processor. A non-intrusive debugging process operates within a debugging mechanism of a digital signal processor. Non-intrusively monitoring in real time predetermined aspects of software execution occurs with the core processing process and occurs in real-time on the processor. An embedded trace macrocell records selectable aspects of the non-intrusively monitored software execution and generates at least one breakpoint in response to events arising within the selectable aspects of the non-intrusively monitored software execution. The present disclosure controls aspects of the non-intrusive debugging process in response to at least one breakpoint.

Description

technical field [0001] The subject matter disclosed herein relates to data processing systems and processes, such as may be used in data communications and similar applications. More particularly, the present invention relates to a novel and improved method and system for digital signal processing debug operations, including providing and utilizing embedded trace macrocells for enhanced debug operations. Background technique [0002] Telecommunications and other types of electronic equipment that support video, complex audio, video conferencing, and other rich software applications increasingly include signal processing. Signal processing requires fast mathematical calculations and data generation with complex and repetitive algorithms. Many applications require real-time computation, ie, signals that are continuous functions of time that must be sampled and converted to digital signals for digital processing. The processor must execute algorithms that perform discrete com...
