Description
Technical field
The invention belongs to embedded processor technology fields, are related to the NDK adaptation layer transplantation method of DSP, especially a kind of
Under CCS5.5 Integrated Development Environment, the adaptation TMS320C6455's based on NDK2.21.2.43 and SYS/BIOS6.35.4.50
NDK adaptation layer transplantation method.
Background technique
NDK (Network Developer ' s Kit) is that the exploitation on embeded processor that is used to that TI is provided is based on net
The development platform of network program, it is current to support TMS320C6000DSP series and arm processor.The platform of support has C64P, C66,
C674, ARM9, Cortex-A8, and Cortex-M3 equipment.TI company provides adaptation layer (NSP, NDK simultaneously for NDK
Support Package), to be adapted to specific hardware platform, serve as the role of network-driven.
Since TMS320C6455 type DSP has excellent performance, cheap, kept so far in industries such as communication, the radars in China
Very high frequency of use, annual consumption it is huge.But TI company is to promote its New DSP, gradually eliminates pair
The adaptation layer of C64P series processors is only supported to NDK2.0.0 in the technical support of TMS320C6455, while NDK2.0.0 is only
It is adapted to CCS3.3 exploitation environment and DSP/BIOS operating system.This causes the ethernet communication function of TMS320C6455 can not be same
Recent systems are compatible, limit it and continue as Communication in China, the best optional DSP model of radar industry.And so far without effectively
Method solves the problems, such as this, and numerous engineers can only develop TMS320C6455 using old tool, using aging method, efficiency
Lowly, a large amount of manpower and material resources are wasted.
TMS320C6455 type DSP in order to have excellent performance, cheap can continue to as industries such as Communication in China, radars
Contribute, it is necessary to the adaptation layer of C64P series processors is transplanted, be adapted to highest version NDK, CCS5.5 exploitation environment and
SYS/BIOS operating system.The present invention provides a kind of NDK adaptation layer transplantation methods.
