Abstract: An audio data transmission system applied in a blade PC for connecting a main system unit of a PC blade with an external audio device is provided. The audio data transmission system comprises a peripheral agent device, a peripheral gateway and a connection management unit. The peripheral agent device is connected to the main system unit. The peripheral gateway is connected to the external audio device and is for providing an identification code. In response to the identification code, the connection management unit pairs the peripheral agent device with the peripheral gateway to establish a communication link between the peripheral agent device and the peripheral gateway for transmitting an audio data.

Abstract: An embedded system includes a CPU, a section-swapping control device, a memory device and a section mapping device. The CPU has a boot code initializing address. The section-swapping control device detects a boot condition of the CPU and thus outputs a swap signal. The memory device includes a first memory section and a second memory section for respectively storing a first boot code and a second boot code. The section mapping device is coupled to the CPU and the memory device. The section mapping device receives the swap signal and thus maps the boot code initializing address to an initial bit address of one of the first and second memory sections such that the CPU is booted according to one of the first and second boot codes.
