单片机编程 Virtex-5, Spartan-DSP FPGAs Ap
Virtex-5, Spartan-DSP FPGAs Application Note
This application note demonstrates how efficient implementations of Digital Up Converters(DUC) and Digital Down Converters (DDC) can be done by leveraging the Xilinx DSP IPportfolio for increased productivity and reduced time to development. Step-by-step ...
单片机编程 开放式汇编器系统的设计
汇编器在微处理器的验证和应用中举足轻重，如何设计通用的汇编器一直是研究的热点之一。本文提出了一种开放式的汇编器系统设计思想，在汇编语言与机器语言间插入中间代码CMDL（code mapping description language）语言，打破汇编语言与机器语言的直接映射关系，由此建立起一套描述汇编语言与机器语言的开放式映射体系。基 ...
单片机编程 PCA9516 5channel I2C hub
The PCA9516 is a BiCMOS integrated circuit intended forapplication in I2C and SMBus systems.While retaining all the operating modes and features of the I2Csystem, it permits extension of the I2C-bus by buffering both the data(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.The I2C ...
单片机编程 PCA9517 Level translating I2C-
The PCA9517 is a CMOS integrated circuit that provides level shifting between lowvoltage (down to 0.9 V) and higher voltage (2.7 V to 5.5 V) I2C-bus or SMBus applications.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of t ...
单片机编程 PCA9518 Expandable 5channel I2
The PCA9518 is a BiCMOS integrated circuit intended forapplication in I2C and SMBus systems.While retaining all the operating modes and features of the I2Csystem, it permits extension of the I2C-bus by buffering both thedata (SDA) and the clock (SCL) lines, thus enabling virtuallyunlimited buses of ...
单片机编程 PCA9519 4channel level transla
The PCA9519 is a 4-channel level translating I2C-bus/SMBus repeater that enables theprocessor low voltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of ...
单片机编程 Input Signal Rise and Fall Tim
All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...

DSP编程 基于DSP与FPGA的多视频通道的切换控制
为了扩大监控范围，提高资源利用率，降低系统成本，提出了一种多通道视频切换的解决方案。首先从视频信号分离出行场信号，然后根据行场信号由DSP和FPGA产生控制信号，控制多路视频通道之间的切换，从而实现让一个视频处理器同时监控不同场景。实验结果表明，该方案可以在视频监控告警系统中稳定、可靠地实现视频通道的切换 ...
