Abstract
A method of accessing a memory of a trellis decoder. The method comprises the steps of writing a first block of data associated with a trellis function to a first memory block; writing a second block of data associated with the trellis function to a second memory block; simultaneously writing a third block of data to a third memory block and reading the second block of data from the second memory block to generate training data; and simultaneously reading data to be decoded from the first memory block and writing a fourth block of data to the first memory block and generating training data associated with the third block of data. A circuit for accessing a memory of a trellis decoder is also described.
