Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] Such as figure 1 As shown, the present invention provides an embedded device, which includes a processor 1 , a parallel RAM memory 3 , a parallel Flash memory 5 , and a serial Flash memory 7 . The processor 1 is provided with a parallel interface and a serial interface, the parallel RAM memory 3 and the parallel Flash memory 5 are connected to the processor 1 through the parallel interface, and the serial Flash memory 7 is connected to the processor 1 through the serial interface.

[0028] Both the parallel Flash memory 5 and the serial Flash memory 7 are used to store executable files of the embedded device system. In this embodiment, the storage capacity of the parallel Flash memory 5 is greater than that of the serial Flash memory 7 .

[0029] If the size of the st...

Abstract

The invention provides an embedded device and relates to the embedded field. The embedded device comprises a processor, a parallel RAM (random-access memory) memory and a parallel Flash memory, wherein the processor is provided with a parallel interface; the parallel RAM memory and the parallel Flash memory are both connected to the processor through the parallel interface; the processor is provided with a serial interface; the embedded device system comprises a serial Flash memory which is connected to the processor through the serial interface. The invention also provides a method for loading and starting the operation of cutting a system executable file thereof. The serial Flash memory having smaller volume is arranged on the embedded device, the cost is lower, and the realizing method is simple. The serial Flash memory is used for memorizing the system executable file of the embedded device which exceeds the memory capacity of the serial Flash memory, thereby efficiently utilizing the memory capacity of the memory and ensuring the accurate starting of the system executable file of the embedded device.

Description

technical field [0001] The invention relates to the embedded field, in particular to an embedded device and a system executable file segmentation loading and starting method thereof. Background technique [0002] In embedded devices such as MP3, MP4, FM and mobile phones, parallel Flash memory is used to store executable files of the embedded device system. Flash memory is a non-volatile memory that can be erased multiple times online, that is, data will not be lost after power failure, and has the advantages of small size, low power consumption, and strong vibration resistance. [0003] Flash memories used in embedded devices are divided into NOR-type Flash and NAND-type Flash. NOR-type Flash memory can directly read the data of the on-chip memory, the speed is faster, but the price is higher, the application program can be run directly on the NOR-type Flash, no need to read the code to the system RAM (Random Access Memory, Random Access Memory) Memory) memory. The inter...
