Abstract

The invention relates to a processor architecture platform system which comprises a computer, a dynamic random access memory and a processor, wherein the computer is provided with a starting program; the dynamic random access memory is connected with the computer, and is used for storing a second part of the starting program; and the processor is respectively connected with the computer and the dynamic random access memory, and is provided with a first control unit, a static memory, an internal read-only memory and a second control unit, wherein the first control unit is used for controlling the dynamic random access memory; the static memory is used for storing a first part of the starting program; the internal read-only memory is used for storing a hardware initialization program of the system; and the second control unit is used for transmitting the first part of the starting program. The processor architecture platform system and starting method thereof can solve the problems of single loading way and complex operation of the traditional starting programs.

Description

【Technical field】 [0001] The present invention relates to a processor architecture platform system and its starting method, in particular to a USB-based processor architecture platform system and its starting method. 【Background technique】 [0002] In current hand-held or vehicle-mounted GPS navigation devices, more and more operating systems such as WinCE and Linux are used, and such software systems require a hardware platform to be loaded and started. For processors that integrate static memory (SRAM for short) or read-only memory (ROM) resources, the more common loading method is the SRAM+NAND Flash method. This method requires the processor to map the first address of SRAM to address 0x0, and then copy the startup program from Flash to SRAM for execution. Due to the characteristics of NAND Flash, the security of its data needs to be guaranteed by a verification mechanism. The disadvantage of this loading method is that it cannot provide such a verification mechanism, a...
