    sfrmat is a Matlab function that provides a spatial frequency response* (SFR) from a digital image file containing a slanted-edge feature. The specific edge-gradient algorithm follows the intent of the standard ISO 12233, developed by Technical Committee ISI/TC 42, for resolution measurements for electronic still pictorial cameras.

    This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.

    JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

    The CoinUtils project is a collection of open-source utilities developed and used by a variety of other projects in the COIN-OR repository. The project includes classes for storing and manipulating sparse matrices and vectors, performing matrix factorization, parsing input files in standard formats, building representations of mathematical programs, comparing floating point numbers with a tolerance, performing simple presolve operations, and warm starting algorithms for mathematical programs, among others.

  • Multirate filters provide a practical approach to designing and implementing finite response (FIR) f

    Multirate filters provide a practical approach to designing and implementing finite response (FIR) filters with narrow spectral constraints. By changing the input data rate at one or more intermediate points the filter lengths and computational rates can be greatly reduced when compared to a standard single-rate filter implementation.

  • Digital Signature Algorithm (DSA)是Schnorr和ElGamal签名算法的变种

    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。
