Computer architectures can use custom logic in addition to general purpose processors to improve performance for a variety of applications. The use of custom logic allows greater parallelism for some algorithms. While conventional CPUs typically operate on words, fine-grained custom logic can improve efficiency for many bit level operations. The commodification of field programmable devices, pa...

This paper presents an implementation of Rivest, Shamir and Adleman (RSA) cryptosystem based on hardware/software (HW/SW) co-design. The main operation of RSA is the modular exponentiation (ME) which is performed by repeated modular multiplications (MMs). In this work, the right-to-left (R2L) algorithm is used for the implementation of the ME as a programmable system on chip (PSoC). The process...

BACKGROUND Advocates of newer implant designs cite high rates of aseptic loosening and failure as reasons to abandon traditional cemented endoprosthetic reconstruction of the distal femur. QUESTIONS/PURPOSES We asked whether newer, modular distal femoral components had improved survivorship compared with older, custom-casted designs. PATIENTS AND METHODS We retrospectively reviewed 254 pati...

BACKGROUND Orthotic devices can be a successful treatment for lower extremity injuries. However, the high cost of custom devices prevents some patients from purchasing them. Some orthotic companies have begun to offer a less expensive, semi-custom alternative. The purpose of this study was to examine whether the semi-custom devices can provide similar rearfoot control and comfort as custom devi...

OBJECTIVE The purpose of this study was to investigate whether extension of the custom base is necessary for enhancement of bond strength, by comparing the debonding forces and residual adhesives of 3 different lingual bracket systems. METHODS A total of 42 extracted upper premolars were randomly divided into 3 groups of 14 each for bonding with brackets having (1) a conventional limited resi...

Background: Genetically Modified (GM) foods are produced using genetic engineering. This survey attempted to identify the presence of GM rice varieties among some imported rice samples in Iran. Methods: From May to July 2016, a total of 50 samples of the imported rice to Iran were obtained, including 20 bulk rice samples from Bandar Abbas custom, Southern Iran and 30 retail rice samples from s...

this paper provides comparative performance analysis of power and area of 4 bit priority encoder using 65nm technology. Two priority encoder approaches are presented, one with semi custom and the other with full custom. The main objective is to compare semi custom and full custom designed layout on the basis of two parameters which is power and area. Both the semi custom circuit simulation and ...
