Abstract
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.
