Problems solved by technology

[0005] 1. After the waveform component is read through GPP, it is then transmitted to the loadable target device through the bus, and the waveform component of the loadable target device is loaded through the passive loading mode. The transmission process needs to be divided into packages, which is complicated and error-prone, and The speed is slow, and the passive loading mode is also a slow loading mode, which makes the whole loading process complicated and slow, and cannot meet the needs of some systems that need to be refactored quickly
[0006] 2. This mode does not support parallel loading. Multiple loadable target devices can only be loaded serially. The loading time of the entire system is the accumulation of the loading time of each loadable target device. When there are many loadable target devices in the system, the system loading time too slow

Abstract

The invention discloses a non-CORBA (Common Object Request Broker Architecture) waveform component loading circuit, and aims to provide a loading circuit capable of improving SCA system loading speed,and reducing reconstruction time. The circuit is realized through the following technical solution: reading loading information, which is passed from loading agent logic equipment to a loading interface drive, by a LocalBus bus reader-writer, using FLASH blocks, which are selected by K configured FLASH block selectors, as current valid blocks by a CPLD loading interface, providing non-CORBA waveform components, which are stored in the current valid blocks, to M DSPs and N FPGAs, and starting the M DSPs and the N FPGAs through K configured resetting signal generators to load the non-CORBA waveform components in the above valid block in parallel; and storing the loading information to K loading status registers of a CPLD, and passing obtained loading results to the loading agent logic equipment through reading the loading information of the K loading status registers in the CPLD.

Description

technical field [0001] The invention relates to software radio technology in the field of wireless communication, in particular to a non-CORBA (Common Object Request Broker Architecture) waveform component loading circuit and method of a software communication architecture. Background technique [0002] Software radio is an important technology in today's communication field. Software Communications Architecture (SCA, Software Communications Architecture) provides a software framework for implementing applications on a software radio platform. The purpose of SCA is to realize the hardware modularization of wireless communication equipment, and the software has portability, reusability and interoperability. The core idea of ​​SCA is to adopt an object-oriented method to design a standardized software system, and to realize different functions by loading different software waveform components into a common hardware platform, so that the upgrading of radio stations only needs t...
