 # hls_max_template
 
-A max function in C++14 using recursive templates for High-Level Synthesis.
+An efficient C++14 description of a max process which finds the maximum of a real array. 
+
+Used in High Level Synthesis, produce the most efficient maximum possible by doing reduction at compile time.
+
+Currently, it produces log2(*N*) (+1 if *N* is odd) stages of *integer_part(N/2)* comparisons, can be easily unrolled or pipelined.
 
 ## Content
-
 This repository provides a [header](sources/modules/max.hpp) which defines two recursive template classes with a `process` public method that find the maximum of an array of any size and any type.
 `max_template` can be used for all possible sizes while `max_pow2` works only with sizes that are power of 2. `max_struct` is used to implement `max_template` and may not be used directly.
 
 ## Usage
 
-something like:
+After including the header ( with `#include "max.hpp"` ), just call the process method like that:
 
     const T max_array = max_template<SIZE>::process(array);
   
-where `T` is a correct type (e.g. `int`, `float`, `ap_uint`, ...), `SIZE` is an unsigned integer known at compile time (e.g. a literal, a constexpr or a preprocessor constant) and `array` is an C-style array of `T` of length `SIZE`.
-`max_pow2` is used the same way but won't work (even if it compiles) if `SIZE` is not a power of 2. 
+where `T` is a correct type (e.g. `int`, `float`, `ap_uint`, ...), `SIZE` is an unsigned integer known at compile time (e.g. a literal, a constexpr or a preprocessor constant) and `array` is a C-style array containing `SIZE` elements `T`.
+`max_pow2` is used the same. However, note that it cannot work (even if it compiles) if `SIZE` is not a power of 2. 
 
 It must be compiled with `--std=c++14` (or `gnu++14` or another equivalent).

+## Perpectives
+
+A template argument to produce either the current description or a more resources friendly (Higher latency and/or lower througput) may be added in the future.
+Another template argument specifying the most comparisons per stages is also considered.
