 HPatchLite is a lite version of [HDiffPatch](https://github.com/sisong/HDiffPatch), tiny code & ram requirements when patch on MCU,NB-IoT,...

 At the same time, the patch memory(RAM occupancy) can also be very small, 
 RAM size = one decompress memory size + input cache size(>=3Byte) when patch.

 HPatchLite 是 [HDiffPatch](https://github.com/sisong/HDiffPatch) 的一个精简(Lite)版，为在MCU、NB-IoT等小型设备上执行打补丁(patch)功能而优化。   
 
-编译后的patch代码(ROM 占用)非常的小，用 Mbed Studio 编译后为 664 字节。 
-提示：设置宏_IS_RUN_MEM_SAFE_CHECK=0可以节省74字节； 
-如果使用了tinyuz并且设置宏_IS_USED_SHARE_hpatch_lite_types=1，可以节省52字节。

 同时，patch时内存(RAM 占用)也可以非常的小， 
 大小为 一个解压缩流需要的内存大小 + patch时输入的缓存区大小(>=3Byte)。
