Abstract
A circuit for encoding a data stream is described. The circuit comprises a non-zero count circuit coupled to receive the data stream and output a count of non-zero coefficients of a block of data of the data stream; a trailing ones detection circuit coupled to receive the data stream and output a number of trailing ones of the block of data; and a memory coupled to the non-zero count circuit and the trailing ones detection circuit and storing encoded data values, the memory outputting an encoded data value for a non-zero coefficient of a block of data based upon the count of non-zero coefficients and the number of trailing ones for the block of data. A method of encoding a data stream is disclosed.
