20140153623 | DEVICE FOR AUTO BAUD RATE DETECTION - A device for auto baud rate detection includes an edge trigger, a counter, at least one register and a central processing unit. The edge trigger detects whether a potential of a transmitted signal is raising or falling. The counter is connected to the edge trigger and uses the edge trigger to count pulse widths of the transmitted signal. The register is connected to the counter and stores the pulse widths. The central processing unit is connected to the register, compares the pulse widths so as to identify a minimal pulse width, and calculates a baud rate according to the minimal pulse width by using a probability density function. Thereby, the device is advantageous for lowering hardware costs, increasing use flexibility, reducing configuration limitation and ensuring accurate baud rate detection. | 06-05-2014 |
