摘要： A method and system provide processing instructions in a multi-threaded process including the use of breakpoint instructions for generating debugging event(s). A debugging event is generated in response to the execution of breakpoint instructions and executes debugging instructions in response to the debugging event. The debugging instructions debug processing instructions in the multi-threaded processor by transitioning at least one or more threads into a debugging mode. A debugging return is generated for reporting the executing debugging instructions in the subset of the threads of the multi-threaded processor.

摘要： 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. A method and system control transferring data between debugging registers and digital signal processor processes in association with a power transition sequence of the digital signal processor. In a digital signal processor, debugging registers associate with the core processor process and the debugging process. Control bits control transferring data among the debugging registers, the core processor process and the debugging process. The control bit prevents transferring data among the debugging registers, the core processor process and the debugging process in the event of a power transition sequence. Control bits also prevent a power transition sequence of the digital signal processor in the event of transferring data among the debugging registers and the core processor process or the debugging process.

摘要： 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. Trusted and untrusted debugging operational control occurs in operating a core processor associated with the digital signal processor. A debugging process within a debugging mechanism associates with the core processor. The core processor process determines the origin of debugging control as trusted debugging control or untrusted debugging control. In the event of trusted debugging control, the core processor process provides to the trusted debugging control a first set of features and privileges. Alternatively, in the event that debugging control is untrusted debugging control, the core processor process provides the untrusted debugging control a second restricted set of features and privileges, all for maintaining security and proper operation of the core processor process.

摘要： 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. Stuffing instructions in a processing pipeline of a multi-threaded digital signal processor provides for operating a core processor process and a debugging process within a debugging mechanism. Writing a stuff instruction into a debugging process registry and a stuff command in a debugging process command register provides for identifying a predetermined thread of the multi-threaded digital signal processor in which to execute the stuff instruction. The instruction stuffing process issues a debugging process control resume command during a predetermined stage of executing on the predetermined thread and directs the core processor to perform the stuff instruction during the debugging process. The core processor may then execute the stuffed instruction in association with the core processor process and the debugging process.

摘要： 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.
