Abstract: A first code generator identifies a value representing a start of a data frame. In response the first code generator outputs a first code representing at least the start of data frame. Fixed parsing components each output a portion of the data located at a respective offset and having a respective data length, in response to receiving the first code from the first code generator. The extracted respective portion of the data is output. For each respective one of a plurality of data messages a finite state machine identifies a length of the respective data message. For each of a plurality of portions of data in the respective data message, the finite state machine reads a length of a respective portion of data, traverses the portion of the data, calculates an associated adjust factor, and outputs a GO control signal and the adjust factor, used by a plurality of variable parsing components.
