SSTL based Low Power Thermal Efficient WLAN Specific 32 bit ALU Design on 28 nm FPGA


In this paper we have designed a Thermal energy efficient 32Bit ALU for network processor, the main objective of this design is to provide better thermal efficiency with respect to existing designs. For that purpose we have used six different members of SSTL I/Os standards on 28nm technology along with consideration of airflow toward hit sink and different frequency on which ALU operate in network processor or any WLAN devices. We have done total power analysis of WLAN operating on different frequencies. We have considered a set of frequencies, which are based on IEEE 802.11 standards. First we did an analysis of IO standard on different frequencies, to find out the most efficient frequency on which device can operate at lowest power consumption and thermally efficient. Later we compared different I/ Os on different frequencies, which we have considered in our paper in order to compare and find out most efficient IO standard. While analyzing we found out that when WLAN device shift from 343.15K to 283.15K, there is maximum thermal power reduction in SSTL135_R as compared to all considered I/O standards. When we compared same I/Os for different frequencies we observed maximum thermal efficiency in SSTL15 at minimum and maximum temperature as compared to all other considered I/O standards. This design has application where 32bit ALU design is considered for designing an electronic device such as WLAN. The design can be implemented on different nano chips for better efficiency depending upon the design requirement.
