This module is responsible for encoding and decoding the serial bytes to/from NCP into MAC APIs to provide seamless working for application similar to stack running in same processor or on NCP.This module is used for Two Processor Approach .
The Two Processor approach basically consists of two devices Host and NCP(Network Co-Processor).The MAC Stack runs on the NCP and the MAC application runs on the Host.The api-parser module is used by the host which will convert the mac api's to necessary command bytes stream (MAC API Encoder) and send it to the NCP. The NCP board will contain the image of serial-if application (MAC Core Stack) and this will receive necessary command bytes encode it to api's and process it and send back command bytes as response which will be decoded in the host by the api-parser module(MAC API Decoder).
