A system for a first device to initialize a second device is disclosed. The initialization bus is coupled between the first device and the second device. During an initialization period, the first device triggers at least one transmission command through the initialization bus to transmit at least one initial value to the second device via the initialization bus.

Method and system for initializing devices

A buffer control method for controlling packets to be stored in a buffer having a data region and a command queue region. First, the number of the packets that can be stored in the data buffer is determined. Then, a count value representing the remained capacity of the data region is updated. Finally, the count value and a value of maximum data length are compared to determine whether to increase the number of the packets that can be stored in the buffer.

Buffer control method and device thereof

Testing methods and chips preventing sampling errors caused by asynchronous effect. The chip comprises a first logic portion driven by a first clock signal with a first operating frequency, and a second logic portion driven by a second clock signal with a second operating frequency. The first operating frequency is higher than the second operating frequency, and is not an integral multiple of the second operating frequency. In the test method, a third operating frequency of a third clock signal is generated according to the second clock signal, in which the third operating frequency is higher than the first operating frequency and is an integral multiple of the second operating frequency. The first clock signal is replaced by the third clock signal and the first logic portion is tested by the third clock signal. The second logic portion is tested by the second clock signal.
