Embodiment Construction

[0038] refer to figure 1 , gives a schematic diagram of the main hardware components of the modem device 1 of the present invention. This hardware architecture forms the link between the telephone line and one or more computers. The telephone line interface 3 is usually a DSL terminal interface using an RJ-11 connector.

[0039] The ADSL modem device 1 also includes a first module 2, the first module 2 contains an analog front end and an application specific integrated circuit (ASIC), which is used to terminate the analog line interface, and convert the digital data from the main controller 4 into an analog bandpass signal, ASIC will be called ADSL ASIC. The analog front-end module consists of a high-pass filter, which filters out Plain Old Telephone Service (POTS) signals and allows ADSL signals to pass through; a hybrid circuit, such as a passive network, which performs 2-wire to 4-wire conversion, or vice commutation for splitting between upstream and downstream signals;...

Abstract

The present invention is related to an electronics device, such as a modem, having an interface operable with a complete protocol stack code in normal operation, and comprising a non-volatile memory, such as a flash memory containing a code for booting said device. <??>The device is characterized in that software of said device is upgradable during a booting operation of said device via said interface, wherein said boot code comprises a lightweight protocol stack code for said interface.

Description

technical field [0001] The present invention relates to an electronic device, such as a modem or the like, which has an interface which operates in normal operation with a full protocol stack code and which includes a non-volatile memory, such as flash memory, containing the code for booting said device. volatile memory. Background technique [0002] Currently, there are several mechanisms by which software updates, bug fixes, etc. for electronic devices, etc. are distributed to users. A first possible mechanism is that a technician arrives at the location of the device that needs to be updated and replaces the portion of the memory that needs to be updated. [0003] More efficient software updates in full operating mode are also known, eg via the Universal Serial Bus (USB). According to a known method, a software update is carried out on the complete operating software, wherein the new software is first downloaded into the SDRAM and then into the flash memory. However, t...
