A method for data transmission in a device coupled to a host via a bus is provided. A sequence of data packets are received from the host and the received data packets are stored into a buffering unit of the device. It is then determined whether a predetermined error has occurred. When the predetermined error has occurred, the buffering unit of the device is locked to stop receiving the data packets. Thereafter, the buffering unit of the device is unlocked according to an unlock request from the host to resume receiving subsequent data packets.

Methods for bus data transmission and systems utilizing the same

An embedded system with authentication includes: a system read only memory (ROM), a processing circuit and an authentication circuit. The system ROM is arranged to store a boot code. In addition, the processing circuit is arranged to process at least according to the boot code in order to perform operations of the embedded system. Additionally, the authentication circuit is arranged to perform authentication on a command script in order to determine whether the command script is authenticated, and is arranged to prevent the command script from being executed by the processing circuit when the authentication circuit determines that the command script is not authenticated, wherein the command script is received from outside a chip where the system ROM, the processing circuit and the authentication circuit are positioned.
