The invention provides a self-guiding method and system suitable for an embedded SPARC processor. The self-guiding method comprises the steps: S1, packaging a guiding loading program, mirror image parameters and an operating system program into a system mirror image of the SPARC processor through a link script; S2, starting an SPARC processor main core from a Nor flash initial address, executing a guiding loading program, initializing a memory and a memory controller, acquiring information of an operating system program by the guiding loading program through mirror image parameters, and writing the operating system program into an address corresponding to an SRAM from the Nor flash; enabling the main core of the SPARC processor to open other cores, so that the other cores start to run, the main core and the other cores jump into addresses corresponding to the SRAM, an operating system program is run, and the guiding process is completed. 本发明提供了一种适用于嵌入式SPARC架构处理器的自引导方法及系统，包括：步骤S1：通过链接脚本将引导加载程序、镜像参数和操作系统程序打包为SP
