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.
Frequency Scale Conversion
From f To f Scale
frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch.
frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear.
frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.
YSS915 (KP2V2) is an LSI for processing Karaoke voice signals.
This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and
key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI
chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that
YSS915 is applicable to various uses.
In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the
surround effect is applied to the movie and music sources for giving the users more enjoyment.
YSS915 is pin compatible with and register compatible with YSS903 (KP2V).
The Fortran 90 Handbook is a definitive and comprehensive guide to Fortran 90
and its use. Fortran 90, the latest standard version of Fortran, has many
excellent new features that will assist the programmer in writing efficient,
portable, and maintainable programs. The Fortran 90 Handbook is an informal
description of Fortran 90, developed to provide not only a readable
explanation of features, but also some rationale for the inclusion of features
and their use. In addition, “models” give the reader better insight as to why
things are done as they are in the language.

Title: STL Tutorial and Reference Guide: C++ Programming with the Standard Template Library (2nd Edition)
Author: David R. Musser / Gillmer J. Derge / Atul Saini / Gilmer J. Derge
Publisher: Addison-Wesley
Page: 560
Edition: 2nd edition (March 27, 2001)
Format: PDF
Summary: The Standard Template Library was created as the first library of genetic algorithms and data structures, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, and value semantics. This guide provides a tutorial, a description of each element of the library, and sample applications. The expanded second edition includes new code examples and demonstrations of the use of STL in real-world C++ software development it reflects changes made to STL for the final ANSI/ISO C++ language standard.
