The start and duration of the burst access is controlled by ADSC, ADSP and ADV and chip select pins. 开始和持续时间的突发存取控制脂肪干细胞,腺病毒和芯片的ADSP和选择引脚。
The SRAM use a new design of two stage address transition detector to filter out the Unwanted chip select glitches when the SRAM is asynchronously operated. 本文提出了一种采用两级电路实现的地址变化探测器。与传统地址变化探测电路相比较,该设计显著提高了SRAM的抗噪声、抗干扰能力。
Respectively, these three parts of the chip select hardware circuit design to provide a detailed program. 分别对这三部分的芯片选择(CS)、硬件电路设计等提供了详尽的方案。
First we construct a whole hardware structure of this system, then study the chip select problem and structure of each module in the digital part, as well as the function partition and cooperation between modules. 首先根据设计目的,确定了系统的总体硬件架构,接着重点研究了数字部分各个硬件模块的芯片选择(CS)和结构设计,以及模块间的分工与合作。
CPLD decoding signal system is mainly generated decoding chip select signals to strobe latches and the chip needed to control by microcontroller, in addition to strobing some control signal. CPLD译码信号系统主要是产生译码片选信号来选通锁存器以及需要单片机控制芯片的选通信号,另外还产生一些控制信号的选通信号。
