This paper presents Quantized Color Pack eXtension (QCPX) ISA to accelerate performance of pixel-oriented media processing applications. The QCPX ISA (with a 32 bit word size) supports two packed, quantized (reduced) 16-bit color pixels represented in a YCbCr (Y: luminance, Cr and Cb: chrominance) color format. Unlike typical multimedia instruction set extensions (e.g., MDMX, MMX, ALTIVEC), QCP...

We show two practical attacks against the Akelarre block cipher. The best attack retrieves the 128-bit key using less than 100 chosen plaintexts and 2 o -line trial encryptions. Our attacks use a weakness in the round function that preserves the parity of the input, a set of 1-round di erential characteristics with probability 1, and the lack of avalanche and one-way properties in the key-sched...

This paper presents Multiply and Accumulate (MAC) unit design using Vedic Multiplier, which is based on Urdhva Tiryagbhyam Sutra. The paper emphasizes an efficient 32-bit MAC architecture along with 8-bit and 16-bit versions and results are presented in comparison with conventional architectures. The efficiency in terms of area and speed of proposed MAC unit architecture is observed through red...
