Getting started with devkit

The article is mainly from Kunpeng DevKit The background , Kun Peng DevKit Overall introduction , Kun Peng DevKit Main functions , Kun Peng DevKit Highlight four parts to illustrate , Let's talk about Kunpeng DevKit There is a basic understanding .

1.  Kun Peng DevKit The background

Most developers develop software in high-level languages . For programming languages , for example C++,Python And so on , Because of the different instruction sets , It cannot run directly on different architecture platforms , So these software need to be migrated .

Different architectures produce different architectures , During software migration , Different platforms have different differences .

We passed a C/C++ From the actual case of , For example, we need to use 64 Bit to compile , Compile instructions in X86 Hekunpeng is different , Nested Function , Assembly code is also different .

Some of the original ones run on X86 Some of the above software , We moved to the Kunpeng platform . First, we need to evaluate whether the software can be migrated for technical feasibility analysis . This is mainly to provide a technical decision basis for software migration . We need to do a specific migration work . For example, the integrated software can run normally on the Kunpeng platform , Ensure that the function is available . Finally, we need to do performance tuning and performance analysis . Ensure that the migrated software can be compatible with Kunpeng platform to the greatest extent .

If all these jobs are done manually . For migration and performance analysts , The requirements for skills and knowledge structure are very high . For example, during the migration process , We first need to manually check the compilation parameter writing options related to the trace , For example, function assembly instructions or some Java package , What's more, it may need further identification .

This memory inconsistency due to platform differences . This workload is relatively large , Then the threshold requirements for engineers are relatively high .
