Embedded equipment and data file downloading method thereof

Abstract

The invention provides embedded equipment, which relates to the field of special purpose computer equipment. The embedded equipment can be switched between an operating mode and a downloading mode according to operating needs, and comprises a processor, a programmable read-only memory, a cache and an external interface, wherein the processor is connected with the programmable read-only memory, the cache and the external interface respectively, and is used for processing downloaded data files in the downloading mode and controlling the running of the embedded equipment in the operating mode; and the programmable read-only memory is used for storing the downloaded data files. The embedded equipment is also provided with a memory card, wherein the memory card is connected with the processor, and imports the downloaded data files into the embedded equipment by the processor in the downloading mode. The invention also provides a data file downloading method for the embedded equipment. By the embedded equipment and the data file downloading method thereof, the problems of dependence on the connection of an external computer, low downloading speed and downloading insecurity of data file downloading of the embedded equipment in the prior art are solved.

Description

technical field [0001] The invention relates to the field of special computer equipment, in particular to an embedded device and a data file downloading method thereof. Background technique [0002] Embedded devices are special-purpose computer devices that are designed for application and based on computer technology. The software and hardware can be tailored to meet the strict requirements of the application system for function, reliability, cost, volume, and power consumption. Embedded devices generally include two parts: hardware and software. The hardware includes processors / microprocessors, memory and peripheral components, etc.; the software part includes operating system software (OS) (requiring real-time and multitasking operations) and applications, applications It controls the operation and behavior of the system, while the operating system software controls the interaction between the application program and the hardware, and is used to realize the functions of c...
