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.

嵌入式操作系統EOS(Embedded OperatingSystem)是一種用途廣泛的系統軟件,它主要應用于工業控制和國防系統領域。EOS負責嵌人系統的全部軟、硬件資源的分配、調度工作,控制協調并發活動;它必須體現其所在系統的特征,能夠通過裝卸某些模塊來達到系統所要求的功能。本示例給出了EOS在InfineonXC167CI處理器上面的實現示例。

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簽名算法的變種,被美國NIST作為DSS(DigitalSignature Standard)。算法中應用了下述參數: p:L bits長的素數。L是64的倍數,范圍是512到1024; q:p - 1的160bits的素因子; g:g = h^((p-1)/q) mod p,h滿足h < p - 1, h^((p-1)/q) mod p > 1; x:x < q,x為私鑰 ; y:y = g^x mod p ,( p, q, g, y )為公鑰; H( x ):One-Way Hash函數。DSS中選用SHA( Secure Hash Algorithm )。 p, q, g可由一組用戶共享,但在實際應用中,使用公共模數可能會帶來一定的威脅。簽名及驗證協議如下: 1. P產生隨機數k,k < q; 2. P計算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 簽名結果是( m, r, s )。 3. 驗證時計算 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,則認為簽名有效。 DSA是基于整數有限域離散對數難題的,其安全性與RSA相比差不多。DSA的一個重要特點是兩個素數公開,這樣,當使用別人的p和q時,即使不知道私鑰,你也能確認它們是否是隨機產生的,還是作了手腳。RSA算法卻作不到。
