Embodiment Construction

[0039] figure 2 The shown baseband chip of the embodiment of the present invention includes: a DSP core 1 , several hardware accelerators 21 - 2n and corresponding controllers 31 - 3n , a message network 4 and a data network 5 .

[0040] The DSP core 1 can transmit configuration messages to at least one controller through the message network 4 , and any controller can transmit configuration messages to at least one other controller through the message network 4 . The DSP core 1 and the hardware accelerators 21 - 2n can share data through the data network 5 .

[0041] The configuration message is used to configure the hardware accelerator. Specifically, the configuration message carries information related to the configuration parameters of the hardware accelerators, and the controllers 31-3n can respectively configure the corresponding hardware accelerators 21-2n based on the acquired configuration messages.

[0042] Further, any or any number of controllers can also transm...

Abstract

The invention discloses a baseband chip and a data processing method thereof. The baseband chip comprises a digital signal processing core, a plurality of hardware accelerators and corresponding controllers, an information network and a data network. The digital signal processing core is suitable for transmitting configuration information to the controller through the information network. The configuration information is used for configuring the hardware accelerators. The controller is suitable for transmitting the configuration information to other controllers through the information network. The digital signal processing core and the hardware accelerators are suitable for sharing the data through the data network. The baseband chip and the data processing method thereof can lower circuit power consumption and improve the real-time performance of the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a baseband chip and a data processing method thereof. Background technique [0002] In an existing communication system, the baseband chip of a communication terminal usually consists of a protocol processor, a digital signal processing (DSP, Digital Signal Processing) core, plus multiple hardware accelerators, and the hardware accelerator is usually tightly coupled with the DSP core. For example, please refer to figure 1 As shown, the baseband processing architecture uses the DSP core as the control core, all hardware accelerators 21-2n, and direct memory access (DMA, Direct Memory Access) can only work after being configured by the DSP core, and data is stored in all hardware accelerators and The flow between the DSP core and DMA also requires the DSP core to be configured. [0003] In the process of data processing, when a hardware accelerator is required to process some data, the ...
