Description

一种类脑计算机操作系统的应用处理程序动态加载方法A method for dynamically loading application processing program of brain-like computer operating system 技术领域technical field
本发明属于新型计算机技术领域，具体涉及一种类脑计算机操作系统的应用处理程序动态加载方法。The invention belongs to the technical field of novel computers, in particular to a method for dynamically loading an application processing program of a brain-like computer operating system.
背景技术Background technique
随着后摩尔定律时代的到来，冯诺依曼体系结构的计算性能由于多方面的瓶颈而不再能够维持高速的增长，基于脉冲神经网络的类脑计算芯片是直接用硬件实现了一些生物神经元模型，并且神经元之间的数据传输都是类似生物神经元之间脉冲。由类脑计算机组成的类脑计算机由于在架构和实现上的天然优势，能够通过运行脉冲神经网络来模拟大脑的部分行为，并且有着较低的功耗和较高的计算性能。With the advent of the post-Moore's Law era, the computing performance of the von Neumann architecture can no longer maintain high-speed growth due to various bottlenecks. Brain-like computing chips based on spiking neural networks directly implement some biological neural networks in hardware. meta-model, and the data transmission between neurons is similar to the pulse between biological neurons. Brain-like computers composed of brain-like computers can simulate part of the behavior of the brain by running spiking neural networks due to their natural advantages in architecture and implementation, and have low power consumption and high computing performance.
一般地，类脑计算机在完成计算任务后会产生大量的结果数据，如膜电压、计算结果等数据。如果类脑计算机产生的数据不经过任何处理，直接存储或者通过网络返回给用户，那么会导致系统产生较大的时延。该时延主要体现在两个方面：一个是数据的多次内存拷贝造成的时延，另一个是数据的网络传输造成的时延。同时由于脉冲神经网络模型的差异性会导致其计算结果在结构上也各不相同，因此，亟需一种动态加载方法，用于在类脑计算机产生结果数据时，能够根据不同的脉冲神经网络模型类型动态地加载不同的应用处理程序，来实现用户所需数据的结构化，从而提升系统整体性能。Generally, brain-like computers will generate a large amount of result data, such as membrane voltage, calculation results and other data after completing the calculation task. If the data generated by the brain-like computer is stored directly or returned to the user through the network without any processing, it will cause a large delay in the system. The delay is mainly reflected in two aspects: one is the delay caused by multiple memory copies of the data, and the other is the delay caused by the network transmission of the data. At the same time, due to the differences of the spiking neural network models, the calculation results are also different in structure. Therefore, there is an urgent need for a dynamic loading method, which can be used according to different spiking neural networks when the brain-like computer generates the result data. The model type dynamically loads different application handlers to realize the structuring of the data required by the user, thereby improving the overall performance of the system.
一般地，现有的动态加载方法都比较复杂，如linux系统提供的kprobe 方式，可以在不重新编译内核的情况下，向内核中动态地插入代码。但是kprobe方式并不适合纯裸机软件系统，有两方面原因：第一，kprobe方式需要建立符号表；第二，kprobe方式性能较差，主要是因为其基于中断的方式，需要保存上下文。再如热补丁技术，其主要用于代码的在线修复及在线更新。热补丁技术同样也需要建立符号表信息，不适合于类脑计算机操作系统。Generally, the existing dynamic loading methods are relatively complex, such as the kprobe method provided by the Linux system, which can dynamically insert code into the kernel without recompiling the kernel. However, the kprobe method is not suitable for pure bare-metal software systems for two reasons: first, the kprobe method needs to establish a symbol table; second, the kprobe method has poor performance, mainly because of its interrupt-based method, which needs to save the context. Another example is the hot patch technology, which is mainly used for online repair and online update of the code. Hot patching technology also needs to establish symbol table information, which is not suitable for brain-like computer operating system.
由于类脑计算机操作系统属于一种静态操作系统，因此，需要一种简单的方案实现类脑计算机应用处理程序的动态加载。Since the brain-like computer operating system is a static operating system, a simple solution is needed to realize the dynamic loading of the application processing program of the brain-like computer.
又因为类脑计算机计算结果处理的频次高，且单次时间短，一般处理时间为毫秒级别，因此需要一种低的性能开销实现应用处理程序的动态加载。And because the brain-like computer has high processing frequency of calculation results and short single time, and the general processing time is millisecond level, a low performance overhead is required to realize the dynamic loading of application processing programs.
