Hardware implemental field oriented bit stream formatter for generating user programmed data formats

摘要

A programmable formatter for providing a data format in response to programmable commands comprises a memory for storing at least program instructions which define the data format; an instruction register for receiving and holding a current program instruction read out of the memory from a given address; a field state machine for indicating when the current program instruction has been completed; an instruction decoder for decoding the program instruction and for specifying information required by a decoded instruction; a repetition counter for counting a number of iterations specified by the current instruction; a data register for storing and outputting fixed patterns specified by the current program instruction; and a next state logic circuit for requesting a next program instruction from the memory when the current program instruction has been completed.
