Fast algorithm for square root of integer and Realization based on fixed-point DSP;

A method for floating-point to fixed-point conversion in fixed-point SoC based on statistical analysis;

Stability analysis of fixed-point digital filters under finite word-length effects;

The algorithm and strategy of block floating point for fixed point DSP;

-At the beginning of hemodialysis, one group is punctured by the "fixed point" method, the other group is punctured by the "interval" method.

This paper presents how to simulate the C language fixed point for DSP control algorithm with industrial computer,and describes a method of Per Unit scale mode,and how to deal with errors and overflow occurred in truncation and round-off in programming with this method.

Objective:Long-distance PCR was applied to site-directed mutagenesis of epilepsy-related gene SCN1A in vitro.

Methods Human proinsulin gene was mutated by the polymerase chain reaction (PCR) for the site-directed mutagenesis method.

Methods Using double primer in vitro site-directed mutagenesis, the mutation was induced into the wild IDUA cDNA.

It presents two methods of how to improve operation accuracy in fix-point DSP by the actual examples and the relative TMS320C54X assemble program.

By the methods of optimizing the surd-sonant judge module,translating floatingpoint to fix-point,using iteration to realize evolution,inquiring table to realizing exceeding function and so on,experiments on the FPGA of SOC/Leon3 show that 45% of hardware resource is reduced and 29% of the real-time capability of algorithm is raised.
