Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0031] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0032] In related technologies, because VDSP needs to meet the requirements of different signal processing scenarios during design, that is, VDSP needs to meet the most complex signal processing scenarios during design, and for simple signal processing scenarios, such as terminal standby scenarios, compared to complex The scene and the stand...

Abstract

The embodiment of the invention discloses a VDSP, a data processing method and communication equipment, and belongs to the technical field of chips. The VDSP comprises a VR, a VALU, a DM and an LSU. The VR is divided into at least two register areas, and the DM is divided into at least two data storage areas which are located in different power domains; the VALU is divided into at least two vectoroperation areas, different register areas, different data storage areas and different vector operation areas are located in different power domains, the VDSP comprises at least two working modes, andthe switching states of the power domains in the VR, the DM and the VALU are different in different working modes; LSU is used for accessing the VR or DM in the activated state, and the VALU is usedfor operating data in the VR through the vector operation area in the activated state. The same VDSP can be in different working modes, and waste of VDSP processing resources due to the fact that theVDSP is in the same working mode in different scenes is avoided.

Description

technical field [0001] The embodiments of the present application relate to the field of chip technologies, and in particular to a vector signal processor (Vector Digital Signal Processor, VDSP), a data processing method, and a communication device. Background technique [0002] VDSP is a component used for signal processing in communication equipment, and it plays an important role in the field of wireless communication. [0003] In modern communication systems, VDSP at the physical layer needs to take into account different demodulation scenarios, such as 4G scenarios, 2G scenarios, and 3G scenarios. In different demodulation scenarios, terminals have different requirements for VDSP data processing capabilities. In related technologies, VDSP is usually designed based on the most complex demodulation scenarios. [0004] Apparently, using the solution in the related art, the VDSP is in the same working mode for different demodulation scenarios (that is, the working mode cor...
