ADI BF DSP的几种常用的图象滤波汇编优化后的代码

/*
** LDF for ADSP-21535.
** 
** This LDF defines an example layout for a system which contains 256K
** of L2 SRAM, with the available L1 SRAM left unused. It does
** not assume the presence of any external memory. See below for
** memory map descriptions.
** 
** There are a number of configuration options that can be specified
** either by compiler flags, or by linker flags directly. The options are:
** 
** USE_PROFILER0
** 	Enabled by -p. Link in profiling library, and write results to
** 	both stdout and mon.out.
** USE_PROFILER1
** 	Enabled by -p1. Only write profiling data to mon.out.
** USE_PROFILER2
** 	Enabled by -p2. Only write profiling data to stdout.
** USE_PROFILER
** 	Equivalent to USE_PROFILER0.
** USE_FILEIO
** 	Link in support for file I/O (fopen, etc). Also necessary
** 	for argc/argv handling.
** LOW64K
** 	Place all code and data in the 0x0000-0xFFFF area of memory.
** 	This option is disabled by default, because that region of
** 	the memory map is external memory, which may not exist.
** CMDLINE
** 	Link exit routines suitable for use with the command-line
** 	simulator ccblkfn, rather than the VisualDSP++ debugger.
** CRT
** 	Link in C/C++ Runtime.
** USERMODE
**	Set up event handlers and go to usermode.
** 
** Memory map.
** 
** The known memory spaces are as follows:
** 
** 0xFFE00000 - 0xFFFFFFFF		Core MMR registers (2MB)
** 0xFFC00000 - 0xFFDFFFFF		System MMR registers (2MB)
** 0xFFB04000 - 0xFFBFFFFF		Reserved
** 0xFFB00000 - 0xFFB00FFF		Scratch SRAM (4K)
** 0xFFA04000 - 0xFFAFFFFF		Reserved
** 0xFFA00000 - 0xFFA03FFF		Code SRAM (16K)
** 0xFF904000 - 0xFF9FFFFF		Reserved
** 0xFF900000 - 0xFF903FFF		Data Bank B SRAM (16K)
** 0xFF804000 - 0xFF8FFFFF		Reserved
** 0xFF800000 - 0xFF803FFF		Data Bank A SRAM (16K)
** 0xF0040000 - 0xFF7FFFFF		Reserved RAM
** 0xF0000000 - 0xF003FFFF		L2 SRAM (256K)
** 0xEF000400 - 0xEFFFFFFF		Reserved ROM
** 0xEF000000 - 0xEF0003FF		Boot ROM (1K)
** 0x00000000 - 0xEEFFFFFF		unpopulated
** 
** The memory sections defined below assume that only L1 and L2 SRAM
** are available. We use L2, and leave L1 for explicit programmer use.
** The file VisualDSP/Blackfin/lib/src/libc/basiccrt.s contains example
** startup code which could be used to initialise the L1 SRAM as cache
** for L2.
