VHDL是由美国国防部为描述电子电路所开发的一种语言,其全称为(Very High Speed Integrated Circuit) Hardware Description Language。 与另外一门硬件描述语言Verilog HDL相比,VHDL更善于描述高层的一些设计,包括系统级(算法、数据通路、控制)和行为级(寄存器传输级),而且VHDL具有设计重用、大型设计能力、可读性强、易于编译等优点逐渐受到硬件设计者的青睐。但是,VHDL是一门语法相当严格的语言,易学性差,特别是对于刚开始接触VHDL的设计者而言,经常会因某些小细节处理不当导致综合无法通过。为此本文就其中一些比较典型的问题展开探讨,希望对初学者有所帮助,提高学习进度。

What is Verilog? ➥ Verilog HDL is a Hardware Description Language (HDL) ➥ Verilog HDL allows describe designs at a high level of abstraction as well as the lower implementation levels ➥ Primary use of HDLs is the simulation of designs ➥ Verilog is a discrete event time simulator What is VeriWell? ➥ VeriWell is a comprehensive implementation of Verilog HDL

The Synthetic PIC Verion 1.1 This a VHDL synthesizable model of a simple PIC 16C5x microcontroller. It is not, and is not intended as, a high fidelity circuit simulation. This package includes the following files. Note that the license agreement is stated in the main VHDL file, PICCPU.VHD and common questions are answered in the file SYNTHPIC.TXT Files: README.TXT This file.. SYNTHPIC.TXT Questions and Answers PICCPU.VHD Main processor VHDL file PICALU.VHD ALU for the PICCPU PICREGS.VHD Data memory PICROM.VHD Program memory (created by HEX2VHDL utility) PICTEST.VHD Simple test bench I used to do testing (optional) PICTEST.CMD My Viewlogic ViewSim command file (again, optional) TEST1.ASM First program I assembled and ran on it.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.

这是I2c网关Id独立烧写程序, 烧写的ID必须要求是:“0~9”、“a~z”、“A~Z”的16为字符才能烧写成功。 其中当是输入的小写字母时,自动转换为大些烧入。 如: 1) # ./burnID 0123456789abcdef 烧入的是:0123456789ABCDEF 2] # ./burnID 0123456789@ cdef 烧入不成功,因为有其他字符 3) # ./burnID 0123456789abcdefDfs 烧入也不成,因为超过16个字符 built-in analog anti-aliasing filters, four 10bit Analog-to-Digital converters, and proprietary digital gain/clamp controller, high quality Y/C separator to reduce cross-noise and high performance free scaler.
