1. An apparatus comprising: a coder/decoder (CODEC) including a first processor and a first buffer, wherein the first processor is configured to analyze audio data samples to detect a keyword and the CODEC is configured to store a set of audio data samples at the first buffer; and an application processor configured to receive the set of audio data samples from the CODEC via a bus, wherein the application processor is configured to initialize a speech recognition engine (SRE) based on the set of audio data samples, and wherein the application processor is further configured to initialize the bus based on an indication from the CODEC that the keyword is detected.
