VHDL/FPGA/Verilog DDR SDRAM控制器的VHDL源代码
DDR SDRAM控制器的VHDL源代码，含详细设计文档。
The DDR, DCM, and SelectI/O&#8482 features in the Virtex&#8482 -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Dig ...

but they should compile without too much difficulty.
* The source files for the AVRcam had the author name and copyright

This document describes how to switch to and program the unisersal serial bus (USB)
analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example
assembly programs for programming and switching to and from the APLL are also
provided in the attached zip file. It is assumed that the reade ...

数学计算 SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems
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 ...

mkdosfs - Make DOS file system utilty.
I wrote this, partially to complement the dosfsck utility written by Werner
Almesberger (who graciously gave me some pointers when I asked for some
advice about writing this code), and also to avoid me having to boot DOS
just to create data partitions (I use ...
数学计算 cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used
cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide.
