Abstract
An apparatus is described comprising: a decoder which decodes a plurality of data streams, the decoder having a state associated with each of the data streams; and state restoration logic to restore the decoder's state upon switching from decoding one data stream to another data stream.
Claims26
An apparatus comprising:
- a decoder to decode a plurality of data streams, said decoder having a state associated with each of said data streams;
- and
- state restoration logic to restore said decoder's state upon switching from decoding one data stream to another data stream.
A method for concurrently decoding a plurality of data streams comprising:
- decoding a first portion of a first data stream in said plurality, said first data stream having a state associated therewith following said decoding of said first portion;
- decoding portions of other data streams in said plurality;
- restoring said state associated with said first data stream;
- and
- decoding a second portion of said first data stream.
2 more elements
An apparatus comprising:
- a plurality of data arrays for storing survivor path data for a plurality of data streams;
- a buffer for storing a plurality of path metric values associated with each of said data streams;
- and
- state restoration logic for selecting a particular data array and a particular set of path metric values associated with a particular data stream upon receiving a signal indicating a switch to decoding said particular data stream.
1 more element
A machine-readable medium having code stored thereon which defines an integrated circuit (IC), said IC comprising:
- a decoder to decode a plurality of data streams, said decoder having a state associated with each of said data streams;
- state restoration logic to restore said decoder's state upon switching from decoding one data stream to another data stream.
