Abstract
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.
