Abstract: An infrared signal generator with an interface for receiving an encoded infrared command; and protocol generation circuitry for generating a bitstream that comprises one or more data words that comprise data to be transmitted and one or more protocol words that describe symbols of an infrared protocol is presented. Optionally, the protocol generation circuitry comprises a first circuit for generating a data word and a second circuit for generating a protocol word. Optionally, the infrared signal generator comprises a carrier frequency generator which is selectively combined with the output of either the first circuit or the second circuit to provide a drive signal for an infrared transmitter.

Abstract: An integrated circuit with a patching function comprises a one-time programmable memory (OTP), a random access memory (RAM), and a control unit. The control unit copies data stored on the OTP into the RAM to obtain a copied image mirroring said data. It checks for presence of one or more patch instructions in the OTP, and, if a patch instruction is found in the OTP, modifies a portion of the copied image based on the patch instruction, to obtain a patched image stored in the RAM. The integrated circuit further comprises a processing unit configured to access the patched image in the RAM. The patch can be provided wirelessly.
