Complexity resource manager for multi-channel speech processing

A multi-channel speech processor comprising:

• a controller capable of interfacing with a variable number of communication channels;
• a complexity resource manager (CRM) executed by said controller configured to process a speech signal from each of said communication channels;
• a memory coupled to said controller configured to store speech signal process time values;
• and
• at least one signal processing unit (SPU) coupled to said memory and to said controller, said SPU configured to encode said speech signals;
• said CRM further configured to:
• calculate a complexity budget from said speech signal process time values, and
• signal said SPU to operate in a complexity reduced mode based on said complexity budget.

A multi-channel speech processor comprising:

• a controller capable of interfacing with a plurality of communication channels;
• a complexity resource manager (CRM) executed by said controller configured to process a speech signal from each of said communication channels;
• a memory coupled to said controller configured to store speech signal process time values;
• and
• a plurality of signal processing unit (SPU) coupled to said memory and to said controller, each said SPU configured to encode said speech signals;
• said CRM further configured to:
• calculate a complexity budget from said speech signal process time values for each said SPU, and
• signal an SPU to operate in a complexity reduced mode based on said complexity budget calculated for the corresponding CPU.

A method for managing the complexity resources of a speech processor having at least one signal processing unit (SPU) configured to encode speech signals, the speech processor capable of interfacing with a plurality of communication channels, said method comprising:

• receiving an input speech signal from one of said communication channels;
• determining the process time consumed in processing prior channels in a cycle;
• calculating a complexity budget based said process time consumed in processing prior channels;
• and
• signaling the SPU to encode said input speech signal in a complexity reduced mode based on said complexity budget.

A speech processing system for processing speech signals in a plurality of communication channels, said speech processing system comprising:

• a complexity resource manager (CRM) configured to process said speech signals in each of said plurality of communication channels;
• and
• a signal processing unit (SPU) in communication with said CRM, said SPU configured to encode said speech signals;
• wherein said CRM is further configured to calculate a complexity budget based on a speech signal process time consumed by said SPU to process said speech signals in a portion of said plurality of communication channels, and to signal said SPU to operate in a complexity reduced mode based on said complexity budget.
