S ino-Africa relations have progressed significantly since the end of the Cold War. In 2006, the Chinese government declared that China will '…unswervingly carry forward the tradition of China-Africa friendship, and, proceeding from the fundamental interests of both the Chinese and African peoples, establish and develop a new type of strategic partnership(More)

—In order to implement a fully-integrated on-chip CMOS power amplifier (PA) for RFID reader, inductors are implemented by bonding wires in the output stage of PA. Comparing with the on-chip inductors in CMOS process, the merit of the bondwire inductor is its high quality factor, leading a higher output power and power efficiency. Also the disadvantage of(More)

—Aiming at the expansive application of RFID technology, design considerations are expatiated to a highly-integrated, multimode, power-controllable transmitter in mobile UHF RFID reader with CMOS process. The transmitter consists of digital section, a baseband circuit, an up-conversion mixer and a gain-variable power amplifier. Multiple data modes can be(More)
Bit stream coding plays an important role in image and video compressing standards. This paper presents a H.264 baseline profile bit-stream decoding solution based on application specific processor. The bit-stream decoder hardware is integrated into the RISC processor as a sub-module of its ALU. It can decode one symbol every clock cycle through one(More)
A modified DSP architecture to accelerate motion estimation (ME) algorithms is presented in this paper. The proposed SIMD and VLIW architecture is a trade-off between ASIC implementation and DSP implementation of ME, which can perform subtract, absolute and add (SAA) operation on 8 pixels and fetch 8 new pixels from memory at the same time. Flexible align(More)
