It is the well-known visual secret sharing (VSS) technique that encrypts a secret image into several share images and, later, decrypts the secret by stacking the share images and recognizing by the human visual system. Due to the perfect secrecy, VSS is one of well-candidate for achieving secure e-commerce. Furthermore, the other visual secret sharing(More)
Low-Power High-Speed graphics processing unit (GPU) is one of the key hardware components in modern mobile devices such as smart phones. This paper presents several methods to improve the execution performance and reduce the power of a previously designed programmable GPU for OpenGL ES 2.0 specification. The GPU has a vectored and(More)
A multi-threaded programmable shader pipeline 3D graphics SoC with support for OpenGL ES 2.0 has been developed and fabricated. The sample chip is ARMv4T compatible with the 3D processing capability of 14.9 Mvertices/s, 3.6 Mpixels/s and up to 4K resolution. The die size is 3.85&#x00D7;3.85 mm<sup>2</sup>, with 2.96M gates on a TSMC 90nm CMOS 1P9M. This new(More)
