摘要： Floating point multiply-accumulate (FMAC) instructions are processed by a logic circuit. A register file stores operands for a FMAC instruction. A multiplier multiplies an operand S1 and an operand S2 from the register file to produce a resultant operand St. An adder adds two operands St and Sd (which is the result of a prior accumulation) to produce the result Sd of the FMAC instruction. A reorder buffer (ROB) stores and reorders entries corresponding to FMAC instructions, and a hazard-checking block detects whether the FMAC instruction contains a potential hazard. A selector selects an output value from the ROB. The operands St and Sd can be supplied via one of a plurality of paths based on a priority of the paths, and the priority for the paths is based in part on output from the hazard-checking block and contents of the ROB.

摘要： An electronic device includes an input interface receiving a power signal, a voltage conversion unit converting the power signal into a voltage signal, a processing unit receiving the voltage signal to operate normally, a load unit, and a control unit electrically connected to the processing unit, the voltage conversion unit and the load unit. The processing unit detects whether the load unit stops operating. In response to the processing unit detecting that the load unit stops operating, the processing unit controls the control unit to cut off an electrical connection between the voltage conversion unit and the load unit, and thereby the voltage conversion unit stops providing the voltage signal to the load unit.

摘要： A power regulation circuit is connected to a voltage supply unit for receiving a power-on voltage supplied by the voltage supply unit and to a voltage management unit for enabling an enable port thereof. The power regulation circuit includes a first regulation unit and the second regulation unit. The first regulation unit is used for outputting an enable signal to the enable port when the power-on voltage is lower than a threshold value such that the voltage management unit can output a first working voltage to a load via a first output port thereof. The first regulation unit stops outputting the enable signal after the expiry of a certain period of time following the drop in a power supply to a level which is below a certain threshold value for a predetermined period.

摘要： A distance measurement method for use in a laser range finding device to measure a distance between the laser range finding device and a target is disclosed. The method comprises the following steps. A laser signal is sent to the target in a first time point. A reflected laser signal reflected by the target is then received. A digital signal having a plurality of signal values ranging from 0 to N is obtained by sampling the reflected laser signal with a sampling signal, wherein N is an integer larger than two. A maximum signal value among the signal values is obtained. The distance is calculated according to the first time point and a second time point where the maximum signal value is generated.
