基于 sc 的嵌入式多媒体控制器设计（Design of embedded multimedia controller based on SC）

基于 sc 的嵌入式多媒体控制器设计（Design of embedded multimedia controller based on SC） At the same time, the power management module can provide a variety of voltage power supply system, including the chip core voltage using 1.8V power supply, the chip I/O part using 3.3V power supply, and some of the conventional chip integrated circuit using 5V power supply. The intelligent power management module solves the different requirements of the power supply of each part of the system, reduces the power consumption, reduces the interference noise between different power supplies, and improves the integration degree of the system. Since the PCI bus is not implemented in the S3C2440 chip, in order to enable the system to have more expansion and upgrading capability, the system bus is extended through the peripheral PCI bus controller chip. The chip supports the PCI2.1 protocol specification. Under the 33MHz bus clock frequency, the peak transmission speed can reach 133MB/s, which can fully meet the requirements of data transmission. The Bluetooth interface and wireless network interface are implemented by PCI bus to meet the requirements of remote data transmission and wireless network. At the same time, the system can connect 2.5 inch or 1.8 Inch small hard disk to realize the mobile storage of user information, and the user can expand the storage capacity as needed. Because the PCI bus controller is adopted in the system, the PCI bus is extended, which makes the system equivalent to a small PC machine in a sense. The user can easily extend and upgrade the hardware system. In order to meet some situations of human-machine interaction, different from the PC system, requiring quick and convenient operation requirements, we use 6.4 inch high brightness color TFTLCD touch screen, the user interacts with the upper multimedia processing software directly through the touch screen, provide a good man-machine interface. Fig. 1 is a block diagram of the hardware structure of the system. SHAPE\*ME
