有了处理时序信息的能力,我们才能构建强大的计算机,因为处理时序信息代表着我们可以把一个芯片的输出作为另一个芯片的输入,从而实现各种复杂的功能。所以我们需要时序逻辑单元 DFF(Data Flip-Flop),DFF 干了一件很简单的事情,就是实现了 x[t+1] = x[t]。 下图展示了组合逻辑单元和时序逻辑单元的区别,其中的时钟...
A True Single-Phase Clock (TSPC) NAND-based reset flip-flop includes a reset functionality to perform a reset operation. The flip-flop with the reset functionality includes a master section and a slave section. The reset functionality is achieved using two transistors in the master section. The...
A new reduced clock-swing flip-flop, named NAND-type Keeper Flip-Flop(NDKFF) is proposed. Compared with other conventional reduced clock-swing flip-flops such as HSFF and RCSFF, NDKFF features simple configuration, which does not have additional clock drivers or does not have additional n- ...
Memory 时序逻辑:out(t)=f(in(t-1)),我们使用flip-flop实现了他进而实现了寄存器和RAM 为什么需要时序逻辑? 1.避免顺序逻辑的毛刺效应 2.支持反馈逻辑 有时间看一下解释的很好https://www.zhihu.com/question/35128735 存储器: 实验:设计register,RAM,PC...

Memory,orRAM.This will be done gradually, going bottom-up from elementaryflip-flopgates to one-bit registers ton-bit registers to a family of RAM chips. Unlike the computer's processing chips, which are based oncombinational logic, the computer's memory logic requires a clock-basedsequential ...
The OR gate between A3 and CSn maps the flip-flop and NAND I/O in different address spaces inside the same chip select unit, which improves the setup and hold times and simplifies the firmware. The structure uses the microcontroller DMA (Direct Memory Access) engines to optimize the transfer...

In this work we propose a novel implementation on recent Xilinx FPGA platforms of a PUF architecture based on the NAND SR-latch (referred to as NAND-PUF in the following) which achieves an extremely low resource usage with very good overall performance. More specifically, a 4 bit NAND-PUF ...
This circuit is a flip-flop or latch, which stores one bit of memory. When you click the set input, it goes low, and this brings the Q output high, even after the set input goes high again. When you click the reset input, it goes low, and this brings the Q output low. If set...
