The present disclosure relates to an intelligent and healthy lighting method and device for an office space micro environment. According to the present disclosure, high-illuminance light can be provided, according to periodic variations of human rhythms and characteristics of office time (i.e., lighting time control data), in the morning to increase rhythmic stimulation to improve alertness of office staff and working efficiency. In addition, the present disclosure effectively solves the problem that conventional lamps cannot meet the requirements of human rhythm health by setting a lighting method having multiple modes (i.e., an awake mode, a rest mode, a relax mode, a work mode, a night mode, and a silence mode) and multiple scenes (i.e., determining a lighting mode according to ambient light data, lighting time control data, and human posture data).

The present invention discloses a method and system for detecting the frame boundary of a data stream received in Forward Error Correction layer in the Ethernet. The present invention can increase the speed of frame boundary detection and the speed of frame synchronization without adding any overheads of hardware.

Method and system for detecting the frame boundary of a data stream received in forward error correction layer in the ethernet

The present invention discloses a frame boundary detection system and a synchronization system for a data stream received by an Ethernet Forward Error Correction layer. The frame boundary detection system includes a shifter, two descramblers, a syndrome generator and trapper. The error trapper includes a big-little endian mode controller for controlling the big-little endian conversion of the error trapper. If the error trapper operates in the big endian mode, the error trapper implements the function of the syndrome generator, operates at the same time with the syndrome generator, and performs a second FEC check, wherein when the shifter performs the FEC check by intercepting data with a length of one frame plus A bits, two start positions of the frame can be verified, where A is a positive integer less than a length of one frame. The invention can improve the frame boundary detection speed and the frame synchronization speed, and increase only a few hardware overheads.
