Abstract (in Japanese) (See Japanese page) 
(in English) GPGPU (General-Purpose computation on GPUs) is a paradigm to use
GPUs (graphics processing units) for general computation.
Due to recent remarkable improvement of GPU, GPU outperforms CPU
in computation ability.
However, most people could not use the ability for general computation
because existing programming languages require knowledge about GPU
hardware architectures and computer graphics for GPGPU computing.
Recently, a new GPU language CUDA (Compute Unified Device
Architecture) has been released from NVIDIA.
The CUDA code is C language style and
has less computational restriction.
Thus, usual operations of C language can run on GPU without much
special knowledge.
In this report, we briefly introduce CUDA language programming and
report a CUDA implemented of PCA-SIFT.
Compared to a CPU implementation,
our CUDA implementation reduced the processing time to around 1/4.
In addition, we also report an interesting phenomenon results useful
for practical use of CUDA.
