We may release PJLIB under + * additional schemes in the future (such as GPL or MPL) to incorporate + * linking with specific application, however, one thing for sure is + * we will NEVER be able to make PJLIB a proprietary software. + * + * @subsection extreme_portable_feat Extreme Portability + * + * PJLIB is designed to be extremely portable. It can run on any kind + * of processors (16-bit, 32-bit, or 64-bit, big or little endian, single + * or multi-processors) and operating systems. Floating point or no + * floating point. Multi-threading or not. + * It can even run in environment where no ANSI LIBC is available. + * + * Currently PJLIB is being ported to: + * - x86, Win32 (Win95/98/ME, NT/2000/XP/2003, mingw). + * - x86, Linux (user mode and as kernel module(!)). + * - alpha, Linux + * And coming up: + * - x86, eCos + * - ultra-II, Solaris. + * - powerpc, MacOS + * - m68k, PalmOS. + * - arm, PocketPC + * + * No other library is known to have this extreme portability! + * + * @subsection small_size_feat Small in Size + * + * One of the primary objectives is to have library that is small in size for + * typical embedded applications. As a rough guidance, we aim to keep the + * library size below 100KB for it to be considered as small. + * As the result, most of the functionalities in the library can be tailored + * to meet the requirements; user can enable/disable specific functionalities + * to get the desired size/performance/functionality balance. + * + * For more info, please see @ref pj_config. + * + * @subsection no_dyn_mem No Dynamic Memory Allocations + * + * The central idea of PJLIB is that for applications to run as fast as it can, + * it should not use \a malloc() at all, but instead should get the memory + * from a preallocated storage pool. There are few things that can be + * optimized with this approach: + * + * - \a alloc() is a O(1) operation. + * - no mutex is used inside alloc(). It is assumed that synchronization + * will be used in higher abstraction by application anyway. + * - no \a free() is required.
