Data sequencer with MUX select input for converting input data stream and to specific output data stream using two exclusive-or logic gates and counter

A system for converting an input data stream having a first order into an output data stream having a second order, the first order being identified by two identifier bits, the system comprising:

• a counter having at least two most significant bit outputs;
• a data sequencer for sequencing the input data stream into the second order, the sequencer comprising:
• a count input that receives data from the counter;
• a data input for receiving the input data stream;
• and
• an output for transmitting the output data stream;
• a first exclusive-or logic element for applying an exclusive-or operation to a first of the two most significant bit outputs of the counter and a first of the two identifier bits identifying the first order, the exclusive-or operation producing a first value that is directed to the count input of the data sequencer;
• and
• a second exclusive-or logic element for applying an exclusive-or operation to a second of the two significant bit outputs of the counter and a second of the two identifier bits identifying the first order, the exclusive-or operation producing a second value that is directed to the count input of the data sequencer.

An apparatus for converting an input data stream having an input format into a output data stream having an output format, the input form being identified by a stream identifier, the apparatus comprising:

• a data stream input for receiving the input data stream;
• a select input for entering a select signal;
• a counter having a first and second plurality of count outputs;
• a stream identifier generator that generates the stream identifier which identifies the input format of the input data stream;
• a first logic gate having a respective input coupled with both the stream identifier generator and at least one of the first respective count outputs, the first logic gate also having an output coupled with the select input;
• a second logic gate having a respective input coupled with both the stream identifier generator and at least one of the first respective count outputs, the second logic gate also having an output coupled with the select input;
• the second plurality of count outputs coupled to the select input;
• and
• a data stream output for forwarding the output data stream in the output format.
