Peripheral device with shared bus interface and operating method thereof

A peripheral device for use in a system including a storage unit coupled to a local bus. The peripheral device has a shared bus interface provided for interfacing with the storage unit and the local bus. The peripheral device also includes core logic coupled to the shared bus interface. When the core logic receives a read/write command with respect to the storage unit through the local bus, it causes the local bus to enter at least a wait state and performs a corresponding data transfer between the peripheral device and the storage unit through the shared bus interface during the wait state. In particular, the peripheral device shares the shared bus interface with the storage unit so as to transfer data.

Automatic Welding Method

An automatic welding method includes a preliminary step and a joining step. The preliminary step is configured to place a metal object having a multi-dimensional curved weld zone on a platform, and to clamp a welding torch with a welding torch clamping device. The joining step is configured to generate a relative movement between a tip of the welding torch and the multi-dimensional curved weld zone of the metal object, and to electrify the welding torch to weld the metal object by way of short circuiting arc transfer. An angle difference between a reference position and an instant position of the welding torch is 0 to 135 degrees when the welding torch welds the metal object, so as to keep the slag from spraying, wherein the welding torch is at the reference position when the tip thereof is pointed straight down towards the ground. 1. An automatic welding method , comprising:a preliminary step placing a metal object with a multi-dimensional curved weld zone on a platform, and clamping a welding torch with a welding torch clamping device; anda joining step generating a relative movement between a tip of the welding torch and the multi-dimensional curved weld zone of the metal object, and electrifying the welding torch in order for the welding torch to weld the metal object by way of short circuiting arc transfer, allowing fish scale patterns to be formed on the multi-dimensional curved weld zone of the metal object;wherein an angle difference between a reference position and an instant position of the welding torch is 0 to 135 degrees when the welding torch welds the metal object, so as to keep the slag from spraying, wherein the welding torch is at the reference position when the tip thereof is pointed straight down towards the ground.2. The automatic welding method as claimed in claim 1 , wherein the platform is a movable platform or an immovable platform.3. The automatic welding method as claimed in claim 1 , wherein the welding torch clamping device is a movable ...
