Embodiment Construction

[0016] Please refer to image 3 , which is a system architecture diagram of a notebook computer according to a preferred embodiment of the present invention. its with figure 2 The difference between the general notebook computer system architecture is that the embedded control unit 308 is a programmable logic circuit and a state machine (state machine) that is relatively cheap and does not require a microprocessor, but has complete functions and scalability. Please refer to Figure 4 , which is a functional block diagram of an embodiment of the embedded control unit 308 of the present invention. Wherein, the embedded control unit 308 includes a plurality of peripheral function controllers. The peripheral function controller is used to provide various peripheral functions required by various manufacturers to control these peripheral devices. And these peripheral function controllers decide whether to start or not according to the needs of customers with selection signals. ...

Abstract

An embedded control unit instead of the programmable processor in notebook computer has multiple built-in peripheral controllers for controlling the peripherals frequently used by multiple notebook computers which can be directly and serially connected. Its advantages are no need of firmware support and low cost.

Description

field of invention [0001] The present invention relates to an embedded control unit capable of controlling different programmable peripherals in a register-based manner, and in particular relates to the design of an embedded control unit suitable for notebook computers, after the unit has been fully verified , can generate RTL (Register Transistor Level register transistor level), and can be integrated into the south bridge chipset (south bridge chipset) to achieve the purpose of reducing costs. Background technique [0002] Since the personal computer industry is quite mature now, many components have been standardized, so the difficulty of design is greatly reduced. Please refer to figure 1 , which is shown as a system architecture diagram of a general desktop computer. The desktop computer includes a central processing unit 102 , a north bridge chipset 104 and a south bridge chipset 106 . Generally, we also refer to the south bridge chipset as a...
