Description of the Invention: [Technical Field] The present invention provides an embedded, controller/keyboard controller and method thereof, which are compatible with various memory access formats, and more particularly, a host system transmits a memory When the device is transferred to a memory device, the instruction compatible conversion is performed by the embedded controller/keyboard controller of the present invention, so that the access command transmitted by the host system is not limited to the memory device. format. [Prior Art] The increasingly advanced and breakthrough of semiconductor process miniaturization technology makes the number of transistors that can be accommodated in an integrated circuit (ic) chip from tens of thousands to hundreds of millions (or even more), so the function of 1C is also It is constantly improving. The original function of the keyboard controller is to control the signal transmission between the system host and the keyboard. However, as the concept of system single chip and multi-function integration is widely used in Ic products, the keyboard controller is gradually upgraded with more The support function is that the keyboard controller on the market can also play the role of an embedded controller. Please refer to FIG. 1A. FIG. 1A is a functional block diagram of an embedded controller/keyboard controller for accessing an industry standard architecture (ISA) format memory device. An embedded controller/keyboard controller 10 is used to mediate a host system 11 to read and write an ISA format memory device 12. In application, the host system (H〇st) ll can be a notebook computer or a personal computer, which transmits an ISA format access command to an ISA format memory device, and then the embedded controller/keyboard controller 1〇 plays the role of signal control between each other. 1284280 Please cooperate with the first A picture. The host system 11 sends an ISA format access command to a host interface unit 1〇1 in the embedded controller/keyboard controller 10, and then sends the signal to the ISA interface unit 103 by the micro control unit 102. The X bus interface is finally accessed by the ISA access device to the delta memory device (IsA format memory 12). However, under the trend of miniaturization of electronic information products, the number of 1C feet is much welcomed and adopted by the market. Therefore, the shortcomings of the ISA format memory device having a large number of pins 12 result in considerable attention to the Series PeHphe fal Interface (SPI) format memory device having a small number of pins. Please refer to the first B diagram. The first B diagram is a functional block diagram of the embedded controller/keyboard controller for accessing a spi format memory device. The biggest difference from the ^ A picture is that the ISA format memory device I is replaced with an SPI format memory device 13. For format compatibility, the host system 'u sends an SPI access command to the embedded controller/keyboard controller. The interface is single 1G and then sent to the signal by the micro control unit s 1G2. An SPI interface unit 104 finally accesses the SPI format access instruction to the memory device (SPI format memory 13). Although the above method satisfies the SPI format memory device 13 with a small number of pins, the embedded controller/keyboard controller 10 needs to provide an SPI interface unit for the purpose of accessing the SPI format memory device 13. In addition, since the SPI format memory can only access the SPI format access command, the host system 11 cannot access the SPI format memory device 13 using the ISA format access command. ~ " The reason is that the inventors have felt that the above-mentioned defects can be improved, and they have devoted themselves to research and cooperated with the application of the theory, and finally proposed a invention which is reasonable in design and effective in improving the above-mentioned defects. 1284280 [Summary of the present j provides that there is no problem with a host system = controller. In order to achieve the above objectives: two fingers: a format compatible memory device performs the function of "key=the controller makes the host system compatible with the invention and is compatible with each other. The keyboard controller includes: a host = The embedded controller/switching control unit and the memory element two control unit and the one-turner keyboard of the body access format are connected to the host system and the embedded control unit (^) The host interface is the control unit, and the switching control unit is electrically connected to the interface unit to electrically connect the conversion device or the packet. The memory device and the memory device are connected to each other. When the device is used, the second/keyboard controller will perform signal processing and command conversion, and the signal format (or signal protocol) of the control instruction can be compatible with (4) the inline two of the viewing dragon access formats. ;, 'Controller signal action method, its method steps include · · 1284280 machine to: save = two embedded controller / keyboard controller inside the main embedded controller / keyboard controller :: two of the main: system ; then make the internal number control or decoding process : reading and fetching instructions to perform the operation, and (4) reading and translating the access instruction to the memory device to perform read and write operations on the recording device. ^本发 ΐ , , , , , , , , , , , , , , The drawings are only for reference and are not intended to limit the invention.
