Abstract

The invention provides a normalization data processing board and integrated equipment inside a BBU machine frame. The normalization data processing board comprises a FPGA used for providing an external interface and an inter-board interface, a DSP chip set, a multi-core CPU and a bridge sheet, the DSP chip set and the multi-core CPU are respectively used for processing data, and the bridge sheet is respectively connected with the FPGA, the DSP chip set and the multi-core CPU through buses between chips. The data processing board achieves the function of processing different data by using a unified hardware structure, and therefore all network cell equipment functions in an LTE system structure can be constructed in a normalized mode based on the unified hardware structure, and the simplification of a network structure is facilitated.

Description

technical field [0001] The invention relates to a normalized data processing board and integrated equipment in a BBU frame, belonging to the field of hardware design of network element equipment. Background technique [0002] In the existing LTE (Long Term Evolution, Long Term Evolution) standard model, the LTE system architecture is as follows figure 1 shown.
