This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.

Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calculation then it described the use in the time-domain finally it analysed several characteristics of the monopole antenna. The arithmetic used in the microstrip antenna is also a quick and economical way to design the antenna.

Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM RISC processor. It features a on-chip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol over USB, SPI, UART. This protocol enables an external host system or processor to control the onchip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerChip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.

主題 : Low power Modified Booth Multiplier 介紹 : 為了節(jié)省乘法器面積、加快速度等等，許多文獻根據(jù)乘法器中架構(gòu)提出改進的方式，而其中在1951年，A. D. Booth教授提出了一種名為radix-2 Booth演算法，演算法原理是在LSB前一個位元補上“0”，再由LSB至MSB以每兩個位元為一個Group，而下一個Group的LSB會與上一個Group的MSB重疊(overlap)，Group中的位元。 Booth編碼表進行編碼(Booth Encoding)後再產(chǎn)生部分乘積進而得到最後的結(jié)果。 Radix-2 Booth演算法在1961年由O. L. Macsorley教授改良後，提出了radix-4 Booth演算法(modified Booth algorithm)，此演算法的差異為Group所涵括的位元由原先的2個位元變?yōu)?個位元。
