Energy Aware 32 Bit Arithmetic and Logical Unit for Error Tolerant Applications

Journal Title: International journal of Emerging Trends in Science and Technology - Year 2016, Vol 3, Issue 1

Abstract

In this era of high end devices, the power efficient architecture is taking responsibility so as to reduce the cost for maintenance. This becomes the critical task for embedded based device, graphical based processor and similar DSP processors which suffers with low power. The core of every embedded device and processor which in turn uses ALU as the workhorse. As we know if workhorse require less power, speed and area so based on that workhorse complete system will make justice with SPAA metrics (Speed, Power, Area and Accuracy). This paper proposed an architecture of 32 bit General Purpose ALU .The critical power dissipation can be avoided by the application of clock gating of the hardware required and improving architectural approach for this in which we divide ALU is four sub block of 8-8 bit. These 32 bit ALU is identify input bit and according to that it will perform operation. Proposed architecture is combination of four 8 bit ALU which is accurate, semi accurate and approximate. Due to these logic we can save power consumption. The synthesized architecture is implemented by Hardware descriptive language (Verilog). Analysis is performing on FPGA (Field Programmable Gate Array) level.
