Consumer infrared (CIR) systems typically are used in remote control systems. Most CIR systems expect a known carrier frequency and encoding scheme. However, there are many applications of a universal CIR receiver which can receive and decode CIR signals regardless of the carrier frequency or encoding scheme. A CIR receiver circuit is disclosed which can both decompose a received CIR signal into run length representation and detect the carrier frequency. The result can then be supplied to a host device for further processing, interpretation and/or actions.

Universal systems and methods for determining an incoming carrier frequency and decoding an incoming signal

A comb filter system that utilizes host memory is disclosed. The comb filter system that utilizes host memory may include a comb filter. The comb filter system that utilizes host memory may include an allocated host memory. The comb filter system that utilizes host memory may include an interface in signal communication with the comb filter and allocated host memory.
