The chapter describes the techniques to design the architecture and micro-architecture for the processor. The case study is created to develop the thought process to evolve the architecture of the pipelined processor. Most of the times, we need to have the processors in the SOC designs. For ...
His areas of expertise include RTL design using VHDL, RTL design using Verilog, complex FPGA-based design, low power design, synthesis and optimization, static timing analysis, system design using microprocessors, high-speed VLSI designs, and architecture design of complex SOCs....
我们看一下Coding Style,作为设计语言的话,Verilog用的越简单越好。当你发现一个人用Verilog做Design,都写的非常花里胡哨,那他大概率是个半桶水。 一个.v尽可能只放一个模块,注意换行。 写组合逻辑的时候,有一点需要注意,考虑所有的情况!尤其是if else或者case语句。如果你不考虑,仿真器会认为你想保持默认值,...
6.3 Verilog RTL 级低功耗设计(上)www.runoob.com/w3cnote/verilog2-rtl-low-power-design-1.html 下表显示了在数字设计的各个层次上可减少功耗的百分比。RTL 级之后,功耗的减少量已经非常有限。 作为一个编写 Verilog 的伪码农,系统级减少功耗的工作也可参与一些,但重点应该放在 RTL 级来减少功耗。 如果...
Verilog RTL 设计:同步FIFO的设计与验证 方法二 接上一篇同步FIFO的设计。其中产生空、满信号的方法是采用一个计数器,判断计数器中的数来确定FIFO的空满状态。这次采用另外一种方法设计同步FIFO。 方法二:将FIFO的读写地址分别拓展一个高位。当拓展的地址最高位相同,其余低位相同时,说明读写地址相同,此时FIFO内没...
Verilog RTL 设计:异步FIFO的设计与验证 之前的两篇博文讨论了同步FIFO的设计和验证,其读写时钟时相同的单一时钟,应用范围有限。 在实际的系统中,经常会遇到多个时钟域传输数据的情况,此时需要数据在跨时钟域上实现无缝传输,且不能有毛刺出现。异步FIFO读写时钟是不相同的,因此可以实现某个频率的写时钟写入再由另一...
RTL Design - Wiley 被引量: 9发表: 2011年 Low complexity bit parallel architectures for polynomial basis multiplication over GF(2m) This makes it very easy for a designer to implement the proposed multipliers using hardware description languages like VHDL and Verilog with minimum knowledge... A Re...
6.4 Verilog RTL 级低功耗设计(下) 门控时钟 通常情况下,时钟树由大量的缓冲器和反相器组成。而时钟信号为设计中翻转率最高的信号,时钟树的功耗可高达整个设计功耗 30%。加入门控时钟(clock gating)电路,可减少时钟树的开关行为,能节省开关功耗。同时,时钟引脚开关行为的减少,寄存器的内部功耗也会减少。所以,采用...
An eagerly anticipated, up-to-date guide to essential digital design fundamentals Offering a modern, updated approach to digital design, this much-needed book reviews basic design fundamentals before diving into specific details of design optimization. You begin with an examination of the low-levels ...
Engineers convert the high-level desired behavior of their design to software code using a hardware description language (HDL) like VHDL or Verilog. The phrase “register-transfer” refers to how the language describes the data flow between registers and how to apply logical operations and ...
