Embodiment Construction

[0062] The digital baseband in the user wireless device is responsible for processing the digital signals required by the physical layer (PHY). figure 1 A simplified functional block diagram of a digital baseband scheme according to the present invention is presented. The antenna 110 and the radio frequency module 120 in the user device are used to process radio frequency data transmission and reception, including upconverting the baseband signal to the transmission frequency and downconverting the received signal to the baseband signal. Digital data processing is performed by the digital baseband module 130 , which includes a physical layer processing unit 140 , a digital signal processing (DSP) unit 150 , and a microcontroller (MCU) unit 160 . The MCU unit 160 is used to control the function of the digital baseband, and the DSP unit 150 is used to further process unprocessed signals at the physical layer.

[0063] Digital baseband processing must be optimized according to t...

Abstract

Techniques are provided aimed at improving the flexibility and reducing the area and power consumption of digital baseband integrated circuits by using stream data processor (210) based modem architecture. Semiconductor companies offering baseband ICs for handsets, face the challenges of improving die size efficiency, power efficiency, performance, time to market, and coping with evolving standards. Software defined radio based implementations offer a fast time to market. Dedicated hardware designs give the best die size and power efficiency. To combine the advantages of dedicated hardware with the advantages of conventional software defined radio solutions the stream data processor (210) is partitioned into a stream processor unit (410), which implements processing functions in dedicated hardware and is hence die size and power efficient, and a flexible stream control unit (430) which may be software defined to minimize the time to market of the product.

Description

technical field [0001] The present invention is related to the data processor in the computing system, especially related to the technology of using the serial data processor to improve the flexibility, reduce the chip area and reduce the power consumption of the digital base frequency integrated circuit in the wireless communication system. Background technique [0002] Semiconductor companies providing baseband chips for mobile phones must face many challenges, such as chip size, energy efficiency, performance, time to market, support for multiple wireless access modes, and evolving specifications. Since dedicated hardware can provide the best chip size and power, it has been widely used in the past. One of the trends in recent years is to adopt software-defined radio (SDR)-based solutions in order to shorten the time to market. Product demand keeps pace with the times and changes rapidly. Early products usually focus on flexibility, while later products usually focus on...
