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 : 為了節省乘法器面積、加快速度等等，許多文獻根據乘法器中架構提出改進的方式，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)後再產生部分乘積進而得到最後的結果。 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個位元變為3個位元。

The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC938 in order to reduce component count, board space, and system cost.
