Allwinner Technology A40i Domestic Development Board – Comprehensive Test of Performance Parameters
The board under test is an Allwinner Technology A40i based development board with rich interface resources, which can lead to dual network ports, dual CAN, dual USB, dual RS485 and other communication interfaces, Bluetooth, WIFI, 4G (optional) modules on board, as well as MIPI LCD, LVDS LCD, TFT LCD, HDMI OUT, CVBS OUT, CAMERA, LINE IN, H/P OUT and other audio and video multimedia interfaces, support dual-screen display, 1080P@45fps H.264 video hardware encoding, 1080P@60fps H.264 video hardware decoding, and support SATA large-capacity storage interface.
The following is the content of the evaluation prepared by the user of the evaluation, welcome to read.
Preface
The development environment was previously experienced, and now a qualitative experience of all aspects of performance.
Running Score
Open WSL terminal
Download the code
git clone https://github.com/eembc/coremark.git
cd coremark/
vi simple/core_portme.h
Modification
#define COMPILER_FLAGS \
FLAGS_STR /* “Please put compiler flags here (e.g. -o3)” */
#endif
为
#define COMPILER_FLAGS \
“-O3” /* “Please put compiler flags here (e.g. -o3)” */
#endif
If -O0 compiles then change to “-O0”
typedef ee_u32 ee_ptr_int;
Change to
typedef unsigned long ee_ptr_int。

This system uses 8 bytes per array element.
————————————————————-
Array size = 5000000 (elements), Offset = 0 (elements)
Memory per array = 38.1 MiB (= 0.0 GiB).
Total memory required = 114.4 MiB (= 0.1 GiB).
Each kernel will be executed 10 times.
The *best* time for each kernel (excluding the first iteration)
will be used to compute the reported bandwidth.
————————————————————-
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 52219 microseconds.
(= 52219 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
————————————————————-
WARNING — The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.

Summary
The above comprehensive performance test, feel that the performance is still very good, the test results are for reference only, because the environment and other factors are not the same measured results will be different, including the storage test method is not very scientific, such as not taking into account the cache. The above test is only a qualitative performance experience, the performance of the board is a comprehensive experience, need to be in the face of real application scenarios to be meaningful, and optimization for the scene is also very important.
