2) digital family equipment receives system upgrade data message and the preservation from telepilot, then data is detected;
3) after the detection data are error-free, the system upgrade data message is written among the EEPROM;
4) after each restarting systems, the system upgrade data message among the EEPROM is loaded into preassigned zone among the RAM;
5) in a single day run among the RAM part of system upgrade when system program among the ROM, the address of then preserving present ROM jumps to system upgrade data message program corresponding among the RAM; Behind the end of run, jump back to the address of current ROM again and carry out following procedure.
The present invention is by the relevant data message of telepilot transmission system upgrading, is written to that EEPROM realizes after error-free after testing.During each system restart, the system upgrade program is loaded into RAM and ROM is used together.In the system program operational process, in case the program address of ROM counter and bug is consistent, system will jump to error correction data (data that system upgrade the is relevant) corresponding address that loads among the RAM.After carrying out error correction data (system upgrade data) end, get back to the original position of program and carry out following procedure.When needs update system ROMPaq, only need the system upgrade data message in the updated stored telepilot to get final product, send to digital family equipment then, can realize that according to said method of the present invention the upgrading of digital family equipment system is upgraded.
Upgrade method of the present invention can be taked following further measure: digital family equipment can receive and preserve system upgrade data message from telepilot by the teledata receiver module described step 2); By state detection module data are detected.By the EEPROM writing module system upgrade data message is written among the EEPROM in the described step 3).Insmod by RAM in the described step 4) system upgrade data message among the EEPROM is loaded into preassigned zone among the RAM.Detect the operation of system program among the ROM in the described step 5) by ROM redirect module, preserve and jump back to the address of current ROM.
Another object of the present invention is achieved by the following technical programs:
The upgrade-system of a kind of digital family equipment provided by the invention comprises ROM, RAM and EEPROM, comprises in addition:
Be used to store and send the telepilot of system upgrade data message;
Be used to receive and preserve teledata receiver module from the system upgrade data message of telepilot;
Be used to detect system upgrade data message that is kept at the teledata receiver module and the state detection module that sends instruction;
Be used to receive write command, and the system upgrade data message is written to EEPROM writing module among the EEPROM from state detection module;
Be used for system upgrade data message with EEPROM and be loaded into that the RAM in preassigned zone insmods among the RAM;
Be used for detecting the operation of ROM system program, the ROM redirect module of control system executive routine in RAM and ROM;
Described teledata receiver module, state detection module and EEPROM writing module are connected to each other, and the EEPROM writing module is also connected among the EEPROM; Described RAM insmods and is connected with EEPROM; Described ROM redirect module connects control ROM and RAM.
In the upgrade-system of the present invention, the teledata receiver module is responsible for receiving and preserving the system upgrade data message that sends from telepilot, and after state detection module detection data are error-free, is responsible for providing data to the EEPROM writing module.State detection module is responsible for detecting the system upgrade data message that is kept at the teledata receiver module, in case mistake does not appear in the system upgrade data message in transmission course, state detection module then sends write command to the EEPROM writing module.The EEPROM writing module is after the write command that receives from state detection module, and the EEPROM writing module is responsible for the data from the teledata receiver module are written among the EEPROM.
After each restarting systems, RAM insmods and is responsible for the system upgrade data message among the EEPROM is loaded into preassigned zone among the RAM.ROM redirect module is responsible for detecting the operation of system program among the ROM, in case run among the RAM part of system upgrade, just be responsible for preserving the address of present ROM, jump to system upgrade program part corresponding among the RAM, behind the end of run, jump back to the address of current ROM again.
The present invention has following beneficial effect:
(1) simple, overcome space and Effect of Environmental.The telepilot that employing stores the system upgrade data message carries out system upgrade, need not system is split, writes error correcting routine, carries out system's merging again then, gets final product and only need carry out writing of error correcting routine by telepilot.
(2) with low cost.Only need change or upgrade and get final product the program of telepilot.
(3) fast effectively.Owing to do not need artificial split system to carry out writing of program, but take telepilot automatically error correcting routine to be written to EEPROM, therefore do not need the outer time of occupying volume, simple and quick.
(4) help promoting use, popularization and the development of digital household appliances product and digital home network.
