The \emph{\productbasenamelong{} Version \productversion{}} |
| 26 |
(or more compactly, |
| 27 |
\emph{\productbasenameshort{}-\productversion{}}) |
| 28 |
is an |
| 29 |
open-source utility library for inexpensive 8-bit, 16-bit, and 32-bit |
| 30 |
microcontrollers and microprocessors. |
| 31 |
|
| 32 |
The functions provided in \emph{\productbasenameshort{}} fall into these categories |
| 33 |
(with some classification ambiguity and overlap). |
| 34 |
|
| 35 |
\begin{itemize} |
| 36 |
\item Arithmetic. |
| 37 |
\item Bounded arithmetic. |
| 38 |
\item Fixed-point arithmetic. |
| 39 |
\item Large-operand and extended-precision arithmetic. |
| 40 |
\item Block memory operations. |
| 41 |
\item Bit-mapped set functions. |
| 42 |
\item Searching. |
| 43 |
\item Sorting. |
| 44 |
\item Array manipulation. |
| 45 |
\item Linear filters. |
| 46 |
\item Non-linear filters. |
| 47 |
\item Vertical counters. |
| 48 |
\item Control system components. |
| 49 |
\item CRC, checksums, and non-cryptographic hashes. |
| 50 |
\item Cryptographic hashes. |
| 51 |
\item Ciphers. |
| 52 |
\item Miscellaneous functions. |
| 53 |
\item Utility functions. |
| 54 |
\item Speed-enhanced development tool replacement functions. |
| 55 |
\end{itemize} |
| 56 |
|
| 57 |
\emph{\productbasenameshort{}-\productversion{}} |
| 58 |
is packaged as two libraries, each with |
| 59 |
a different purpose: |
| 60 |
|
| 61 |
\begin{itemize} |
| 62 |
\item The \index{general library}``general library'' contains functions not normally provided |
| 63 |
with development tools. The general library is described by |
| 64 |
every chapter in this document except Chapter \ref{csef0}. |
| 65 |
\item The \index{replacement library}``replacement library'' (not yet implemented |
| 66 |
for any platform) contains |
| 67 |
speed-enhanced replacements |
| 68 |
for functions packaged with development tools, in those cases |
| 69 |
where some optimization could be performed or where an alternate |
| 70 |
and faster algorithm is known. The replacement library is covered by |
| 71 |
Chapter \ref{csef0}. Functions in the replacement library |
| 72 |
generally are designed to boost speed at the expense of program |
| 73 |
memory and/or RAM\@. Use of the replacement library is optional. |
| 74 |
The replacement library may not exist for all platforms. |
| 75 |

\section{Supported CPU Cores and CPU Core Variants} |

%Section tag: lcv0 |

\label{ciov0:sscv0} |
| 84 |
|
| 85 |
The CPU core and the development tool chain are closely tied together in terms |
| 86 |
of the usability of a library. A library compiled for a different CPU core |
| 87 |
usually won't function, but a library compiled using a different set of |
| 88 |
development tools may also not function (due to differences in object file formats, |
| 89 |
differences in calling conventions, etc.). For this reason, |
| 90 |
the CPU core and development tool chain are bundled together (see Table \ref{tbl:ciov0:sscv0:01}) |
| 91 |
and sometimes referred to only as |
| 92 |
``CPU core''. |

\index{versioning (library)}Version numbers of the library are of the |
| 184 |
form \emph{j.m-} (example: \emph{2.5c}) where: |
| 185 |
|
| 186 |
\begin{itemize} |
| 187 |
\item \emph{j} is the major version number, a non-negative integer. |
| 188 |
This version number is returned by the |
| 189 |
\index{UcuMfLibVerMajRxx()@\emph{UcuMfLibVerMajRxx($\cdot$)}}\emph{UcuMfLibVerMajRxx($\cdot$)} |
| 190 |
function (\S{}\ref{cmsc0:slvf0}, p. \pageref{cmsc0:slvf0}). |
| 191 |
\item \emph{m} is the minor version number, a non-negative integer. |
| 192 |
This version number is returned by the |

\index{UcuMfLibVerMinMicRxx()@\emph{UcuMfLibVerMinMicRxx($\cdot$)}}\emph{UcuMfLibVerMinMicRxx($\cdot$)} |

function (\S{}\ref{cmsc0:slvm0}, p. \pageref{cmsc0:slvm0}). |
| 195 |
\item \emph{-} is the micro version number, a non-negative integer. The micro version number |
| 196 |
is represented as a letter in documentation (for example, the `c' in `2.5c'). |
| 197 |
This version number is returned by the |
| 198 |
\index{UcuMfLibVerMinMicRxx()@\emph{UcuMfLibVerMinMicRxx($\cdot$)}}\emph{UcuMfLibVerMinMicRxx($\cdot$)} |

function (\S{}\ref{cmsc0:slvm0}, p. \pageref{cmsc0:slvm0}) as an 8-bit integer. |

the letter `b' by 1, etc. |

\index{naming conventions (library)}% |
| 214 |
A typical binary library file name is ``\emph{libucu\_g\_2\_5c\_1\_1.sm8}''. |
| 215 |
In order, the binary library file name contains the following components: |
| 216 |
|
| 217 |
\begin{itemize} |
| 218 |
\item The characters \emph{libucu\_} (a constant string |
| 219 |
to identify the library). |
| 220 |
\item \emph{g\_} or \emph{r\_} to indicate whether the library |
| 221 |
is the `general' or the `replacement' library. |
| 222 |
\item The version number of the library followed by an underscore |
| 223 |
(example: `\emph{2\_5c\_}'). |
| 224 |
\item The CPU core integer identifier, followed by an underscore. (This integer |
| 225 |
is selected from Table \ref{tbl:ciov0:sscv0:01}.) |
| 226 |
\item The CPU core variant integer identifier. (This integer is selected from the table |
| 227 |
of variants specific to the CPU core: for example, Table \ref{tbl:ciov0:sscv0:02} or |
| 228 |
Table \ref{tbl:ciov0:sscv0:03}.) |
| 229 |
\item A period followed by a filename extension traditional for the |
| 230 |
development tools and that CPU core and CPU core variant. |
| 231 |

A typical function name within the general library is |
| 242 |
`\emph{UcuLfU16FiltAFiltRxx}'. Function names within the general library |
| 243 |
usually consist of the following components, with some components optional: |
| 244 |
|
| 245 |
\begin{itemize} |
| 246 |
\item The character string `\emph{Ucu}'. |
| 247 |
\item Two characters representing the function family (selected from |
| 248 |
Table \ref{tbl:ciov0:slcv0:sfnc0:03}). |
| 249 |
\item The fundamental data type on which the function operates and/or returns. (\emph{U16} means |
| 250 |
a 16-bit unsigned integer, \emph{U16a} means an array of unsigned integers, etc.) |
| 251 |
\item A name for the function, indicating what it does. |
| 252 |
\item Qualifiers for the function. These may include input argument sizes, in the case that |
| 253 |
there are variants of the function that accept different input argument sizes. These |
| 254 |
may also include different levels of sophistication in handling invalid or sentinel |
| 255 |
values of inputs. |
| 256 |
\item The interrupt compatibility code (Table \ref{tbl:ciov0:slcv0:sfnc0:01}), capitalized. |
| 257 |
\item The interrupt mask modification code (Table \ref{tbl:ciov0:slcv0:sfnc0:02}), in lower case. |
| 258 |
\item The shared data modification code (Table \ref{tbl:ciov0:slcv0:sfnc0:02b}), in lower case. |
