Abstract
A signal processing unit and a method for using the signal processing unit. The signal processing unit comprising at least two Digital Signal Processors (DSPs) and at least one memory for storing data. The DSP is adapted for signal processing and is capable of accessing the at least one memory. According to an embodiment, the signal processing unit is an Orthogonal Frequency-Division Multiplexing (OFDM) transceiver. The OFDM transceiver is adapted to receive and transmit signals.
Claims18
A signal processing unit comprising:
- at least two sequential Digital Signal Processors (DSPs) adapted for signal processing;
- and
- at least one memory for storing data, said at least one memory being accessible by at least one of said sequential DSPs.
A method for using at least two Digital Signal Processors (DSPs) comprising:
- dividing a signal processing functionality into at least two sub-functionalities;
- classifying said at least two sub-functionalities according to their consumption requirements;
- determining an organization of the at least two DSP for said at least two sub-functionalities;
- and
- sequencing said at least two DSP units and enabling data sharing between said at least two DSP units, according to said organization.
An Orthogonal Frequency-Division Multiplexing (OFDM) transceiver comprising:
- a transceiver unit adapted to receive and transmit signals;
- and
- at least two sequential Digital Signal Processors (DSPs) adapted for processing received and transmitted signals.
