High speed data weighted averaging (dwa) to binary converter circuit

A method, comprising:

• receiving a data weighted averaging (DWA) data word;
• identifying a first bit location in said. DWA data word where a string of logic 1 bits begins;
• identifying a second bit location in said DWA. data word where said string of logic 1 bits ends;
• selecting a sequence of binary values which represent possible numbers of logic 1 bits present in the DWA word starting from the identified first bit location;
• choosing one binary value from said sequence using the identified a second bit location;
• and
• outputting the chosen binary value as a binary word identifying a number of logic 1 bits which are present in said DWA data word.

A method, comprising:

• receiving a first data weighted averaging (DWA) data word;
• processing said first DWA data word to identify a first bit location associated with an ending of a first string of logic 1 bits in said first DWA data word;
• generating a second DWA. data word including a second string of logic 1 bits that begins at said first bit location;
• processing said second DWA data word to identify a second bit location associated with an ending of the second string of logic 1 bits in said second DWA data word;
• using the first bit location and second bit location to identify a number of logic 1 bits present in said second DWA data word;
• and
• outputting a binary value which is equal to said identified number.

A circuit, comprising:

• a latch circuit configured to first latch a first data weighted averaging (DWA) data word and then latch a second DWA data word;
• a first detector circuit configured to identify a first bit location in said first DWA data associated with an ending of a first string of logic 1 bits in said first DWA data word;
• a second detector circuit configured to identify a second bit location in said second DWA data word associated with an ending of a second string of logic 1 bits in said second DWA data word;
• and
• a DWA-to-binary conversion circuit configured to convert second DWA data word to a binary word by using the first bit location and second bit location to identify a number of logic 1 bits present in said second DWA data word and outputting a binary value for said binary word which is equal to said identified number.
