What is the difference between the programmer firmware and the router firmware?
Firmware is a program written in EROM (Erasable Read Only Memory) or EEPROM (Electrically Erasable Programmable Read Only Memory). Firmware refers to the device “driver†saved in the device. Through the firmware, the operating system can implement the specific machine's operation according to the standard device driver. For example, the optical drive, recorder, etc. have internal firmware. Firmware is the software that serves as the most basic and lowest-level job of a system. In the hardware device, the firmware is the soul of the hardware device. Because some hardware devices do not have other software components other than the firmware, the firmware also determines the function and performance of the hardware device. The firmware is generally stored in an electrically erasable read-only memory (EEPROM) or flash memory (FLASH) chip in a device, and can generally be upgraded by a user through a specific refresh program. In general, the software that serves as the foundation and the bottom of a digital product can be called firmware, such as basic input/output system BIOS (Basic Input/Output System) on the computer motherboard. In the past, more professionals called it. It firmware. Usually the programs stored in these hardware cannot be directly read or modified by the user. In the past, under normal circumstances there is no need to upgrade the firmware. Even if a serious bug is found in the firmware, it must be replaced by the professional with the chip that has written the program. Early firmware chips generally use ROM design. Its firmware code is solidified in the production process and cannot be modified by any means. With the continuous development of technology, it has become an urgent requirement for users to modify the firmware to adapt to the ever-updated hardware environment. Therefore, EPROM (Erasable Programmable ROM), EEPROM, and flash have become available. These chips can be repeatedly written to allow the firmware to be modified and upgraded. The firmware can be said to be the nerve center, which can also be called COMBO's operating system. It consists of many modules: drive, control, decode, transfer, check, etc. Only under its control can the COMBO work properly. At the same time, the firmware also comes with many additional features, such as error correction technology, secure burning technology, playback control technology, and so on. In fact, the key technology in the COMBO optical drive firmware is the identification of various discs, which is distinguished from the chemical layer of the disc by recognizing the density of the data grooves in CD, CD-R(W) and DVD discs. Completed. When the disc is placed in the drive, the control chip containing the firmware issues an instruction after the optical drive receives the operation command. The laser head sequentially issues DVD reads, CD-ROM reads, and CD-R writes, CD-RWs according to the instructions. Erasing the four laser trials, if you receive feedback, determine what kind of disc it is. According to this operating procedure, the general DVD-ROM disc needs to be identified once, the CD disc needs to be identified twice, and the CD-R and CD-RW have to go through three times. It is clear that the level of firmware production determines the quality of COMBO drives. As can be seen from the COMBO optical drive, the firmware of the hardware device has an almost equal status with its hardware, and the firmware may be more important in some degree. Because only writing excellent firmware programs can fully and intelligently play the role of hardware, and excellent firmware can also make up for some hardware defects. Depending on the model and version of the router, download the firmware on the computer first, then open the downloaded firmware in the browser's router interface to upgrade. The wireless router firmware is equivalent to the desktop computer's windows system. Different routers have different firmware. Different types of wireless router firmware cannot be exchanged. Firmware is usually packaged in a flash integrated circuit when the wireless router is shipped from the factory. Today's flash integrated circuits usually use an 8-pin package and have more pins. It is soldered to the router's motherboard and is equivalent to a desktop computer's hard disk. Some fanatical wireless router enthusiasts use open-source router firmware to brush into different wireless routers to increase power and functionality. The premise is that the memory and flash integrated circuits of the wireless router need to be modified or enlarged. In terms of computer metaphorically speaking, the official firmware is the computer's operating system, Xp, win7, etc., but each boot must pass the BIOS self-test, and then load the system file, the programmer firmware is to contain both.
