8051上的CRC8校验 A CCITT-8 CRC calculator. The source contains both the calculated (smaller but slower) version, and the table driven (faster but larger) version.
graspForth is my humble attempt at a Forth-in-C that has the following goals:
GCC ......... to support all 32-bit micros that GCC cross-compiles to.
Relocatable . to be able to run in-place in either Flash or Ram.
Fast ........ to be "not much" slower than an assembly based native Forth.
Small ... ...

Compare a protein sequence to a protein sequence
database or a DNA sequence to a DNA sequence database using the
Smith-Waterman algorithm.[.wat815.] \fCssearch3\fP is about 10-times
slower than FASTA3, but is more sensitive for full-length protein
sequence comparison.
The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively.
The functions in this package are accurate, but they are far s ...

In recent years, cellular voice networks have transformed into powerful packet-switched
access networks for both voice communication and Internet access. Evolving Universal
Mobile Telecommunication System (UMTS) networks and first Long Term Evolution
(LTE) installations now deliver bandwidths of sev ...
A decade ago, I first wrote that people moved, and networks needed to adapt to the
reality that people worked on the go. Of course, in those days, wireless LANs came
with a trade-off. Yes, you could use them while moving, but you had to trade a great
deal of throughput to get the mobility. Although ...
