Purpose

With the progress of artificial intelligence (AI) technology, social implementation such as image recognition using AI technology, automatic driving, and natural language processing is rapidly progressing. Especially in the edge computing field, since it is necessary to realize AI technology with higher efficiency, startups mainly in the United States and China and major vendors are accelerating their entry into AI hardware, and even in Japan Not only that, there is an urgent need to develop human resources and industries for hardware to accelerate AI processing such as LSI and FPGA.
Against this background, we will carry out this contest, in addition to the conventional AI technology development centered on software, we are aiming to develop human resources and startups with AI hardware in mind, as well as industry development utilizing these technologies. In this contest, we will develop AI hardware using FPGA and set the hardware system development that considers edge computing including hardware and software (network model and system optimization) as an issue.

The output of the segmentation result (JSON file) can be confirmed, and there is no big difference between the IoU value calculated from the result and the IoU value displayed on the leaderboard.
-The segmentation result submitted during the contest period displayed on the leaderboard exceeds the standard IoU = 0.6.
-The IoU of the segmentation result submitted during the contest period displayed on the leaderboard is far below the standard IoU = 0.6 (less than half), and it is not difficult to apply in practice.
-Implementation report has been submitted.

*The standard IoU is displayed on the leaderboard as a benchmark.

IoU calculation procedure

1.For evaluated images, the average overlap (pixel level) for ground truth and prediction areas will be calculated.
2.The average for step 1's results will be calculated for all test images.




About processing speed

Reference information for obtaining the Ultra96 board to use for this contest

・Subjected board for this contest is Ultra96-V2.
・Regarding method to obtain: There are two ways to obtain it.

1. Provided from this contest
- Although limited in number, the Ultra96 board will be provided after review for the contest participants. For those of you who wish to be provided, please apply through the "application form for board offer document review".
- Provided board includes an AC adapter, power conversion cable, and JTAG board.

2. Obtain from the Avnet website
- You can purchase from here.
- We recommend you to purchase the following related parts along the purchasing of the board.
JTAG board for Ultra96: It is necessary to connect the UART (serial) consol.
・Avnet recommended AC adapter, power conversion cable
 - Power supply
 - Conversion connector

Regarding the errata of Ultra96 board
The errata from Avnet is published the following site.
http://avnet.me/Ultra96-V2_Errata

The errata particularly has the following known issues:
・Reboot issue of Ultra96-V2
 - Ultra96-V2 When the load of the PL part goes up high, MPSoC reboots.
 - Ultra96-V2 It is posted on the errata reporting page.
This is caused by the reset operation in MPSoC that was triggered by the PowerGood signal's drop when a specific threshold is exceeded while the IC called PMIC is monitoring the Vccint voltage.
- In the current V2 board, a reset is applied when a set threshold is exceeded due to increase in current consumption of the PL section.
- How to distinguish the PL power supply current setting is as follows.


・Also for boards with power limits of 3.5A and 4.0A, The limit of this errata can be relieved to about 5.5A by revising the board and changing the setting of PMIC. A complete set of countermeasure procedures prepared by Avnet can be downloaded from below.
