Abstract: A higher frequency clock and a lower frequency clock are locked at a predetermined phase relationship. A total number of pulses of the higher frequency clock occurring between two sequential rising edges of the lower frequency are calculated. A count start signal is generated in response to a rising edge of the lower frequency clock. A value of a lower frequency clock count is set in response to the count start signal. The value of the lower frequency clock decrements in accordance with a frequency of the higher frequency clock. When the value of the lower frequency clock has decreased by the total number of pulses of the higher frequency clock occurring between two consecutive rising edges of the lower frequency minus 1, a synchronization signal is generated for indicating occurrence of the predetermined phase relationship between the higher frequency clock and the lower frequency clock.

Then, the test pattern stored in the first memory is hardware-simulated. If an external interrupt is received during the simulation of the test pattern, the second memory region is accessed and the interrupt instructions are hardware-simulated. Thereafter, the simulated result of the interrupt instructions is self-tested to obtain a first verification result, and the hardware design is verified according to the first verification result.

Abstract: A monitor viewing angle adjusting assembly mainly including a monitor, a supporting arm assembly, and a base. The supporting arm assembly includes two parallel and symmetrical supporting arms which each includes a first arm portion and a second arm portion extending in opposite directions in one plane and slightly bent toward each other at their joint. The monitor and the base are pivotally connected to circular ends of the first and the second arm portions of the supporting arms, respectively, via turning-limit assemblies and locating brackets. The monitor can be turned relative to the supporting arms and the supporting arms can be turned relative to the base, so that the monitor can be adjusted to almost any angular position relative to the base and a viewer may select a viewing angle most suitable for him. When the monitor is adjusted to be parallel with the base, the whole monitor assembly can be hung on a vertical wall to effectively save the space required to pack and store the monitor assembly.
