This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.

The Audio File Library provides a uniform programming interface to standard digital audio file formats. This library allows the processing of audio data to and from audio files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun .snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The library also supports compression (currently G.711 mu-law and A-law and IMA and MS ADPCM) as well as PCM formats of all flavors (signed and unsigned integer, single- and double-precision floating point).

The same two-stage decoder as above. However, when transforming the symbols prior to Viterbi decoding, the amplitude information is ignored and only the phase of the received symbol is employed in the metric computation stage.

The Reed-Somolon code is specified by the finite field, the length (length <= 2^m-1), the number of redundant symbols (length-k), and the initial zero of the code, init_zero, such that the zeros are: init_zero, init_zero+1, ..., init_zero+length-k-1

zemax源码： This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.
