摘要：Recently,real-time processing systems for bio-signal of the muscles generated by the movement of the user have been *** impulse response(FIR)filter for bio-signal processing in bio-signal process systems is composed of multiple multiplier and adder of *** makes the chip area increase *** solve this problem,a low-area digital FIR filter is proposed in this paper,which can reduce the chip area.

摘要：Typically,a variety of digital devices are built into the *** digital devices in order to develop a variety of applications PC,various devices such as smart phones should be easily *** so far the interface of these devices has not been a unified approach. Development of various types of devices to easily shall be equipped with various interfaces such as UART,SPI,I2C. However,there follows a lot of hardware problems to greatly increasing the number of I/O *** I/O are four types based on the same *** port is controlled the software approach to operate UART,SPI, I2C,etc.
