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.

Bootloading the TMS320VC5506/C5507/C5509 A digital signal processor (DSP) through the on-chip universal serial bus (USB) peripheral is part of the standard bootloader provided on the device. This document describes the procedures for physically connecting the DSP to a USB host, invoking the USB bootloader on the DSP, generating the correct boot table file, and downloading the boot table from the host to the DSP via USB.

Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check for bit unstuffing errors]. Otherwise complete and fully functional. There is currently no test bench available. This core is very simple and is proven in hardware. I see no point of writing a test bench at this time.

Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).

實(shí)用USB術(shù)語詳解。USB是一種“主-從”式總線，包括一個(gè)主機(jī)和多個(gè)從機(jī)。從機(jī)稱作外設(shè)，在USB術(shù)語中也稱作功能部件。主機(jī)稱作主設(shè)備。所有USB傳輸都由主機(jī)啟動(dòng)；外設(shè)總是響應(yīng)傳輸，不會(huì)啟動(dòng)傳輸。最常用的主機(jī)是PC機(jī)，主機(jī)通過USB-A連接器連接到下行設(shè)備。嵌入式主機(jī)不包括PC機(jī)，而是用一個(gè)微控制器作為專用主機(jī)，或許只能與一類USB設(shè)備通信。
