Kernel device in wireless sensor network and implementation method thereof

Abstract

The invention discloses a kernel device in a wireless sensor network and an implementation method thereof. The method includes the following steps: a code block generator is activated by a scheduler to convert the jump instruction of the code segment of an application, so that the jump instruction can be cascaded and matched with the next code block to be executed; a plurality of code blocks are set into a code page in a kernel space, and reside in a program memory; when the execution of the code blocks in the program memory meets a branch statement, execution is jumped into a kernel, the kernel searches a jump destination address, and thereby the kernel and the application can alternately obtain the response of a processor. Since the kernel device in the wireless sensor network and the implementation method thereof carry out binary conversion during code loading and the converted binary codes reside in the memory space, the kernel can obtain the processor control right at any time, moreover, because the kernel policy ensures that the codes of the application can be operated for multiple times when being loaded each time, the execution speed of the application is increased to a certain degree, and the energy overhead is saved in the whole wireless sensor network.

Description

technical field [0001] The invention relates to a kernel control system of a single chip microcomputer system and a method thereof, in particular to an improvement of a kernel realization device in a wireless sensor network and an realization method thereof. Background technique [0002] In the prior art, with the decrease of computing cost and the smaller and smaller size of microprocessors, a large number of wireless sensor networks have been put into use. Waiting time. At present, the applications of wireless sensor networks are mainly concentrated in the following fields. [0003] 1. Environmental monitoring and protection [0004] As people pay more and more attention to environmental issues, more and more environmental data need to be collected. The emergence of wireless sensor networks provides convenience for random research data acquisition, and can also avoid the traditional data collection methods. Intrusive damage to the environment. Wireless sensor netwo...

AI Technical Summary

Problems solved by technology

[0019] In short, the clock cycle restart system technology in the prior art is generally implemented by external hardware, which increases additional overhead; moreover, the large restart time interval does not essentially solve the problem that the operating system cannot get the CPU for a long time

At the same time, other existing system technologies applied to wireless sensor network nodes do not take into account the mechanism of system protection, making it difficult to run large-scale applications in the network
