- 16-bits fixed-point PID controller
- License: Freeware

This simulation illustrates the effects of the fixed-point computations on the closed-loop precision for a 16-bits PID controller. The rounding mode, the point where the truncations take place and the format width for the internal variable have a significant action on the closed-loop permanent error. Three versions of the same PI(D=0) controller are implemented : i) double (floating point), ii) 16 bits single precision (fixed point) and iii) 16-bits double precision (fixed point)..

- Converting Models from Floating Point to Fixed Point for Production Code Generation
- License: Freeware

An essential step in embedded software development, floating- to fixed-point conversion can be tedious, labor-intensive, and error-prone. System engineers frequently design algorithms in floating-point math, usually double-precision. This format represents the ideal algorithm behavior but takes little account of the algorithm's final realization in production software and hardware. Software engineers and suppliers in mass production environments often need to convert these algorithms to fixed-point math for their integer-only hardware. As a result, multiple iterations between system and software engineers are often required.

- ANALYZER for RECOVER Fixed/Floppy Disk
- License: Freeware

ANALYZER for RECOVER Fixed/Floppy Disk V0.3 FREEWARE visually reports on bad sectors in system area of floppy disk. You can check if Boot Sector, FAT 1, FAT 2, and ROOT FOLDER sectors are good or bad. You find how much of remaining file system can help recover files when you use RECOVER Fixed/Floppy Disk. While RECOVER Fixed/Floppy Disk (RFD) brings simplicity into data recovery, ANALYZER for RECOVER Fixed/Floppy Disk V0.3 gives a head start to using RFD. When Boot Sector on floppy is bad, WINDOWS 98SE displays a window with this error message: The disk in drive A: is not formatted: Do you want to format it now? When 1st FAT sector on floppy is bad, WINDOWS 98SE displays the same error message for reasons known to itself.

Fixes menu to the same place in window regardless of user scrolling using position:fixed in css if it is available to remove any flicker. Has two levels of graceful degradation: it is repositioned after the scroll if the browser doesn't support position:fixed in css. If the browser is too old to do even that or javascript is disabled, it will just stay in its initial place..

- Rgrow
- License: Freeware

RGrow resizes fixed length records e.g. RGrow.exe MyFile.seq 500 600 will grow each record from 500 to 600 bytes by padding binary zeros. Will also truncate records. These are not the old and new sizes of the file, but of the fixed length records in the file. If you increase the record size, each record will be padded with nulls. The entire file will grow as a result. This program may be freely copied and used for any purpose except military. C source included. Works as a Windows Console app from the DOS command prompt..

- Kalman filter(fixed point version)
- License: Freeware

In this implementation of tracking a ball, we will track a live ball using Kalman filter. The tracking will switch to autorun mode when the sight of the ball is lost and Kalman will estimate the motion based on it's previous states There are two models. One model is a simple simulation of the fixed point version of Kalman filter. It reads a video with a ball moving along a ramp and tracks the motion of the ball. The second model Targets the TI DSP. This Model generates code for the TI DSP..

- 16-bits fixed-point PID implementations in C
- License: Freeware

The effect of fixed-point arithmetic in 16-bits PID controller C routines on the closed-loop precision is shown in this Simulink model. Two Simulink blocks that implement single and double precision 16-bits PID C routines are generated with the LCT. The C sources are supplied for user modifications if required. Controllers work with 16-bits data and coefficients word lengths. Coefficients and data fixed-point numbers have respectively 12-bits and 10-bits fractionnal part. For a reference step excitation, you will see that the permanent errors for the fixed-point pids do not equal zero. Without rounding (look inside model for rounding mode switching), the single precision pid exibits an error about 8 data lsb when the double precision one is just around 2 lsb.
