Abstract

The invention discloses an LPC interface access device and method based on a Feiteng platform and a notebook computer. The device comprises a Feiteng CPU and an EC, wherein the Feiteng CPU comprises an LPC interface, and the EC comprises a keyboard controller, a Super IO, a power supply management channel and a port address processing unit; the LPC interface of the Feiteng CPU is used for accessing an IO port of the EC and carrying out read-write operations; the port address processing unit is used for converting an IO port address of the EC into the IO port address which can be accessed by the LPC interface of the Feiteng CPU; the keyboard controller is used for interacting with the Feiteng CPU by virtue of the port address processing unit; the port address processing unit accesses the power supply management channel by virtue of the read-write operations to the Super IO; and the power supply management channel is used for carrying out information interaction with the LPC interface of the Feiteng CPU after the processing of the port address processing unit and the Super IO. According to the LPC interface access device, the problem of communication between the Feiteng CPU and the EC can be solved, and the cost and the workload of research and development engineers are not increased.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to an LPC interface access device and method based on a Feiteng platform. The present invention also relates to a notebook computer with the above-mentioned LPC interface access device based on the Feiteng platform. Background technique [0002] Laptops on the X86 platform all use Intel or AMD CPUs, and the solution between them and EC has already been maturely used. EC, or embedded controller, is responsible for tasks such as notebook computer matrix keyboard, touch panel, special function keys, notebook computer battery intelligent charge and discharge management, and temperature monitoring. The Feiteng platform CPU, that is, the Feiteng CPU, adopts the ARM architecture and occupies an important position in the field of domestic processors. Because it is in its infancy, there are inevitably some flaws. The LPC interface of the FT CPU can only access 4-byte aligned add...
