摘要:
Methods and systems for processing signals in a communication system are disclosed and may include pipelining processing of a received HSDPA bitstream within a single chip. The pipelining may include calculating a memory address for a current portion of a plurality of information bits in the received HSDPA bitstream, while simultaneously storing on-chip, a portion of the plurality of information bits in the received bitstream that is subsequent to the current portion. A portion of the plurality of information bits in the received HSDPA bitstream that is previous to the current portion may be decoded during the calculating and the storing. The calculation of the memory address for the current portion of the plurality of information bits may be achieved without the use of a buffer. Processing of the plurality of information bits may be partitioned into a functional data processing path and a functional address processing path.

In a video processing system, a method and system for dynamically configurable DCT/IDCT module in a wireless handset are provided. A processor may be used to configure a quantization scheme and video format mode of operation and to configure a processing network in a DCT/IDCT module. The mode of operation may depend on whether the received video signal is in JPEG, MPEG, and/or H.263 format. The processing network may be configured into a DCT processing network configuration or an IDCT processing network configuration based on whether the received video signal is to be encoded or decoded respectively. The DCT/IDCT module may comprise a FIFO, an adder/subtractor, a multipler/accumulator, a plurality of digital dividers, and a de-quantizer. The plurality of digital dividers may comprise a 12-bit divider and an 7-bit divider. The mode and configuration modifications may be dynamically performed during operation of the wireless handset.

A baseband processing module includes TX processing components, a processor, memory, an RX interface, and a cell searcher module. The TX processing components receive outbound data, process the outbound data to produce a baseband TX signal, and output the baseband TX signal to a RF front end of the RF transceiver. The RX interface receives a baseband RX signal from the RF front end carrying a WCDMA signal. The cell searcher module receives the baseband RX signal, scans for WCDMA energy within the baseband RX signal, acquires slot synchronization to the WCDMA signal based upon correlation with a Primary Synchronization Channel (PSCH) of the WCDMA signal, acquires frame synchronization to, and identify a code group of, the WCDMA signal based upon correlation with a Secondary Synchronization Channel (SSCH) of the WCDMA signal, and identifies the scrambling code of the WCDMA signal based upon correlation with a Common Pilot Channel (CPICH) of the WCDMA signal.

A baseband processing module for use within a Radio Frequency (RF) transceiver includes a downlink/uplink interface, TX processing components, a processor, memory, RX processing components, and a turbo decoding module. The RX processing components receive a baseband RX signal from the RF front end, produce a set of IR samples from the baseband RX signal, and transfer the set of IR samples to the memory. The turbo decoding module receives a set of IR samples from the memory, forms a turbo code word from the set of IR samples, turbo decodes the turbo code word to produce inbound data, and outputs the inbound data to the downlink/uplink interface. The turbo decoding module performs metric normalization based upon a chosen metric, performs de-rate matching on the set of IR samples, performs error detection operations, and extracts information from a MAC packet that it produces.

Certain aspects of a method and system for hardware and software shareable DCT/IDCT control interface are provided. A single DCT/IDCT interface may be utilized to provide hardware or software control of a DCT/IDCT module. During hardware control the DCT/IDCT module may be utilized for JPEG compression, for example. During software control a CPU may utilize the DCT/IDCT module for audio, software, and/or video applications, for example. The interface may enable selecting a quantization table for use by the DCT/IDCT module. The interface may also enable selecting encoding or decoding operations to be performed by the DCT/IDCT module. The interface may also enable toggling between a first and a second portion of a data buffer utilized by the DCT/IDCT module. Moreover, the interface may enable starting processing of a data block by the DCT/IDCT module and indicating when the DCT/IDCT module has completed processing the data block.

The RX processing components receive a baseband RX signal from the RF front end, produce a set of IR samples from the baseband RX signal, and transfer the set of IR samples to the memory. The turbo decoding module receives at least one set of IR samples from the memory, forms a turbo code word from the at least one set of IR samples, turbo decodes the turbo code word to produce inbound data, and outputs the inbound data to the downlink/uplink interface. The turbo decoding module performs metric normalization based upon a chosen metric, performs de-rate matching, performs error detection operations, and extracts information from a MAC packet that it produces.
