Abstract:
PURPOSE: An apparatus and a method for capturing GPS signals are provided to prevent the reduction of total accumulated values and the loss of reception sensitivity by changing codes of accumulated values at outside of a bit boundary when bits is inverted. CONSTITUTION: A GPS/CDMA reception unit(100) receives a GPS signal and a network support signal from a GPS satellite and a base station, respectively. A CDMA modem(102) is used for decoding the network support signal and providing a coherent signal. A correlation unit(104) performs a process for calculating a correlation between the GPS signal and a PRN code. An FFT unit(110) performs FFT calculations which dose not convert data from the correlation unit at bit boundary and converts data from the correlation unit at outside of bit boundary. A processor(106) is used for deciding the bit boundary information by using the decoded network support signal, providing the bit boundary information to the FFT unit, and cohering the GPS signal with the PRN code. A memory(112) is used for storing the output data of the correlation unit and the output data of the FFT unit. A memory controller(108) is used for controlling the movement of the data of the correlation unit, the processor, the FFT, and the memory.

PURPOSE: A structure for fastening an FPC(Flexible Printed Circuit) for an optical pickup is provided to reduce work processes and save expense by fastening the FPC to a base with the use of a fastening clip. CONSTITUTION: A penetrating hole(100a) is formed on the base(100). A fastening clip(110) is inserted into the penetrating hole in order to fasten the FPC(30) to the base. The fastening clip is equipped with a head(111) and an inserting part(112) inserted into the penetrating hole connected to the head. At an end of the inserting part, a stopper(112b) for preventing the fastening clip inserted into the penetrating hole from being separated from the penetrating hole is formed.
Abstract:
Disclosed are an SoC for providing access to a shared memory via a chip-to-chip link, an operation method of the SoC, and an electronic system having the SoC. An electronic system of the present invention comprises: a memory device; a first semiconductor device including a memory access path for access to a CPU and the memory device; and a second semiconductor device having access to the memory device through the memory access path of the first semiconductor device. When the CPU of the first semiconductor device is inactive, it is possible to respond to the request of a remote semiconductor device while reducing power consumption by allowing the second semiconductor device to access the memory device with the memory access path active without the intervention of the CPU.
