+# tlsf
+Two-Level Segregated Fit memory allocator implementation.
+Written by Matthew Conte (matt@baisoku.org).
+Released under the BSD license.
+
+Features
+--------
+  * O(1) cost for malloc, free, realloc, memalign
+  * Extremely low overhead per allocation (4 bytes)
+  * Low overhead per TLSF management of pools (~3kB)
+  * Low fragmentation
+  * Compiles to only a few kB of code and data
+  * Support for adding and removing memory pool regions on the fly
+
+Caveats
+-------
+  * Currently, assumes architecture can make 4-byte aligned accesses
+  * Not designed to be thread safe; the user must provide this
+
+Notes
+-----
+This code was based on the TLSF 1.4 spec and documentation found at:
+
+	http://www.gii.upv.es/tlsf/main/docs
+
+It also leverages the TLSF 2.0 improvement to shrink the per-block overhead from 8 to 4 bytes.
+
+History
+-------
+2016/04/10 - v3.1
+  * Code moved to github
+  * tlsfbits.h rolled into tlsf.c
+  * License changed to BSD
+
+2014/02/08 - v3.0
+  * This version is based on improvements from 3DInteractive GmbH
+  * Interface changed to allow more than one memory pool
+  * Separated pool handling from control structure (adding, removing, debugging)
+  * Control structure and pools can still be constructed in the same memory block
+  * Memory blocks for control structure and pools are checked for alignment
+  * Added functions to retrieve control structure size, alignment size, min and max block size, overhead of pool structure, and overhead of a single allocation
+  * Minimal Pool size is tlsf_block_size_min() + tlsf_pool_overhead()
+  * Pool must be empty when it is removed, in order to allow O(1) removal
+
+2011/10/20 - v2.0
+  * 64-bit support
+  * More compiler intrinsics for ffs/fls
+  * ffs/fls verification during TLSF creation in debug builds
+
+2008/04/04 - v1.9
+  * Add tlsf_heap_check, a heap integrity check
+  * Support a predefined tlsf_assert macro
+  * Fix realloc case where block should shrink; if adjacent block is in use, execution would go down the slow path
+
+2007/02/08 - v1.8
+  * Fix for unnecessary reallocation in tlsf_realloc
+
+2007/02/03 - v1.7
+  * tlsf_heap_walk takes a callback
+  * tlsf_realloc now returns NULL on failure
+  * tlsf_memalign optimization for 4-byte alignment
+  * Usage of size_t where appropriate
+
+2006/11/21 - v1.6
+  * ffs/fls broken out into tlsfbits.h
+  * tlsf_overhead queries per-pool overhead
+
+2006/11/07 - v1.5
+  * Smart realloc implementation
+  * Smart memalign implementation
+
+2006/10/11 - v1.4
+  * Add some ffs/fls implementations
+  * Minor code footprint reduction
+
+2006/09/14 - v1.3
+  * Profiling indicates heavy use of blocks of size 1-128, so implement small block handling
+  * Reduce pool overhead by about 1kb
+  * Reduce minimum block size from 32 to 12 bytes
+  * Realloc bug fix
+
+2006/09/09 - v1.2
+  * Add tlsf_block_size
+  * Static assertion mechanism for invariants
+  * Minor bugfixes 
+
+2006/09/01 - v1.1
+  * Add tlsf_realloc
+  * Add tlsf_walk_heap
+
+2006/08/25 - v1.0
+  * First release
