摘要： Systems and methods for controlling the audio volume of an audio signal in an HDA codec having a programmable processor such as a DSP, wherein the codec receives digital audio signals and audio volume control verbs over an HDA bus, and the audio volume levels associated with the audio volume control verbs are used by the processor in the generation pulse width modulated (PWM) output signals, thereby controlling the audio volume levels of the output signals. The processor may be configured to adjust non-volume parameters such as PWM deadtime, in addition to adjusting audio volume, based on the audio volume levels. The codec may be implemented in a PC or other system that implements an HDA system that includes the HDA bus and HDA codec.

摘要： Systems and methods implemented in a PC for enabling communication between an application executing on the CPU and a DSP that is incorporated into a codec in the High Definition Audio (HDA) system, wherein the communication is carried out via the HDA bus. In one embodiment, an HDA codec includes one or more conventional HDA widgets coupled to a programmable processor such as a DSP. The codec includes a set of registers that are configured to store HDA verbs and data transmitted via the HDA bus. The programmable processor is configured to identify verbs that indicate associated information is a communication from an application executing on the CPU, read the associated information, and process the information according to the associated verbs. The information may be program instructions, parametric data, requests for information, etc.

摘要： Systems and methods for booting a programmable processor such as a DSP that is incorporated into an HDA codec. The codec and a system memory containing boot program instructions are connected to an HDA bus. In a first mode, the DSP receives boot program instructions via the HDA bus and boots using these instructions. In a second mode, the DSP boots from instructions that are contained in a memory that is connected to the DSP. In one embodiment, the memory connected to the DSP is a component of a plug-in card, and the DSP is configured to determine whether the plug-in card is present, then boot from the memory on the plug-in card if it is present or boot from the system memory via the HDA bus if the plug-in card is not present.

摘要： Systems and methods for “shadowing” a target codec to provide additional features that are not available in the target codec. In one embodiment, an audio amplification system includes a High Definition Audio (HDA) bus, and an HDA controller, a conventional HDA codec and a shadow HDA codec coupled to the HDA bus. The conventional codec receives audio data and commands from the HDA controller via the bus and processes them to generate an output audio signal. The shadow codec snoops the audio data and commands on the HDA bus that are targeted to the conventional codec. The shadow codec processes the snooped audio data and commands to generate a second audio output. The shadow codec does not communicate with the HDA controller and is transparent to the controller. The shadow codec does not request enumeration from the HDA controller and does not receive an address from the HDA controller.
