An Efficient and Effective Detailed Placement Algorithm Global Swap To identify a pair of cells that can be swapped to reduce wirelength (others are fixed). 2. Vertical Swap Swap a cell with a nearby cell in the segment above or below. 3. Local Re-ordering Re-order consecutive cells locally to reduce wirelength. 4. Single-Segment Clustering Place cells optimally within a segment.

嵌入式操作系统EOS(Embedded OperatingSystem)是一种用途广泛的系统软件,它主要应用于工业控制和国防系统领域。EOS负责嵌人系统的全部软、硬件资源的分配、调度工作,控制协调并发活动;它必须体现其所在系统的特征,能够通过装卸某些模块来达到系统所要求的功能。本示例给出了EOS在InfineonXC167CI处理器上面的实现示例。

Application (fix point) for playing MP3 data on embedded systems. mp3play is designed to be able to play mp3 data files within the local filesystem (which can be a network filesystem), or fetch files to play via http over a network. For the http case the address can specify a streaming MP3 server.

This is the source code for encryption using the latest AES algorithm. AES algorithm is also called Rijndael algorithm. AES algorithm is recommended for non-classified use by the National Institute of Standards and Technology(NIST), USA. Now-a-days AES is being used for almost all encryption applications all around the world.

Digital Signature Algorithm (DSA)是Schnorr和ElGamal签名算法的变种,被美国NIST作为DSS(DigitalSignature Standard)。算法中应用了下述参数: p:L bits长的素数。L是64的倍数,范围是512到1024; q:p - 1的160bits的素因子; g:g = h^((p-1)/q) mod p,h满足h < p - 1, h^((p-1)/q) mod p > 1; x:x < q,x为私钥 ; y:y = g^x mod p ,( p, q, g, y )为公钥; H( x ):One-Way Hash函数。DSS中选用SHA( Secure Hash Algorithm )。 p, q, g可由一组用户共享,但在实际应用中,使用公共模数可能会带来一定的威胁。签名及验证协议如下: 1. P产生随机数k,k < q; 2. P计算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 签名结果是( m, r, s )。 3. 验证时计算 w = s^(-1)mod q u1 = ( H( m ) * w ) mod q u2 = ( r * w ) mod q v = (( g^u1 * y^u2 ) mod p ) mod q 若v = r,则认为签名有效。 DSA是基于整数有限域离散对数难题的,其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开,这样,当使用别人的p和q时,即使不知道私钥,你也能确认它们是否是随机产生的,还是作了手脚。RSA算法却作不到。
