To help overcome limits to the density and speed of conventional SRAMs, we have developed a five-transistor SRAM cell. The newly developed CMOS five-transistor SRAM cell uses one word-line and one bit-line during read/write operation. This cell retains its data with leakage current and positive feedback without refresh cycle. The new cell size is 18% smaller than a conventional six-transistor SRAM...
RFID tags have gradually become popular tools for identification of products. To ensure the secure information transaction of tags, a scheme of RFID system authentication protocol based on Elliptic Curve Cryptography (ECC) is proposed. However, hardware implementation of ECC processor for RFID tags is a challenge for the requirements of low-power consumption and low-cost chip resource. In the paper...
It is well-known that shifting can replace a constant multiplication if the constant is a power of 2. We extend this idea in such a way that by employing more than 2 barrel shifters and a supplementary multiplier we can design a very efficient constant multiplier for general constants. With a support of variable precision computation, we can achieve high computational efficiency while maintaining...
In this paper, we develop a novel way to achieve Mesh+Local Trees (MLT) flow in encounter. By blending the advantages of CTS and ClockMesh into one clock design flow, MLT is guaranteed to have smaller skew, and further optimize mesh structure to achieve lower power. MLT provides real loading sum value instead of estimating for global Mesh structure; another feature of this flow is that it provides...
