Because it will be mandatory for every car to be equipped with Car Black Box, it is expected that many ICs for Car Black Box also will be integrated. As x by wire is introduced to the several part in vehicle, the demand of automotive semiconductors are increasing. This paper describes the design process of Car Black Box system IC. Describing the design process in the hardware and software, it was shown in the verification using MFC(Microsoft Foundation Class) program whether the required data such as image, location and other vehicle control status information was recorded and recovered. SoC for Car Black Box system consists of 8051 processor, CAN (Controller Area Network) controller, JPEG compressor, SD controller for dumping the data from memory buffer to SD card, ROM for programming and SRAM acting as memory buffer. System on Chip (SoC) is the effective method to implement embedded system like car black box, which consists of processor, memory, I/O peripheral and several interfaces. So the topic of this paper is to develop the Embedded controller for Car Black Box using SoC (System on Chip) technique. Unlike general electronic control units (ECUs) as PCB or module, car black box implemented on a single chip can reduce its size, power consumption and the cost. This paper describes the design process of car black box system IC. As energy consumption of the proposed system is reduced by 66.8 % on average, the surveillance time of the proposed system can be increased by three times consequentially. According to experiment, the energy consumption of the proposed system is decreased up to 25.1 % (by 33.2 % on average) of conventional video event data recorder. Because the most valuable information in the event is right before or at the moment of event detection, the proposed system records video from 10 s before the event detection. Operating time of the proposed system is considerably extended by duty-cycling of the two encoders in the event-driven operation the system mainly stays in event detection mode and wakes up only when an event is detected. Duty-cycling of two different encoders, which are a low-power encoder and a high-compression encoder, are employed to implement the low-power video event data recorder. In this chapter, we propose a design of low-power video event data recorder which records events such as movement of objects, or impact to the camera itself. Due to limited battery capacity, reducing power consumption of mobile surveillance camera like a video event data recorder is important to extend surveillance time.
