  Observation datasets acquired by the Hyper Suprime-Cam (HSC) on the Subaru
Telescope for NASA's New Horizons mission target search were analyzed through a
method devised by JAXA. The method makes use of Field Programmable Gate arrays
and was originally used to detect fast-moving objects such as space debris or
near-Earth asteroids. Here we present an application of the method to detect
slow-moving Kuiper Belt Objects (KBOs) in the New Horizons target search
observations. A cadence that takes continuous images of one HSC field of view
for half a night fits the method well. The observations for the New Horizons
Kuiper Belt Extended Mission (NH/KEM) using HSC began in May 2020, and are
ongoing. Here we show our result of the analysis of the dataset acquired from
May 2020 through June 2021 that have already passed the proprietary period and
are open to the public. We detected 84 KBO candidates in the June 2020 and June
2021 datasets, when the observation field was close to opposition.
