The heavily-threaded data processing demands of streaming multiprocessors (SM) in a GPGPU require a large register file (RF). The fast increasing size of the RF makes the area cost and power consumption unaffordable for traditional SRAM designs in the future technologies. In this paper, we propose to use embedded-DRAM (eDRAM) as an alternative in future(More)
Inherently error-resilient applications in areas such as signal processing, machine learning and data analytics provide opportunities for relaxing reliability requirements, and thereby reducing the overhead incurred by conventional error correction schemes. In this paper, we exploit the tolerable imprecision of such applications by designing an(More)
With every process generation, the problem of variability in physical parameters and environmental conditions poses a great challenge to the design of fast and reliable circuits. Propagation delays which decide circuit performance are likely to suffer the most from this phenomena. While Statistical static timing analysis (SSTA) is used extensively for this(More)
In view of device scaling issues, embedded DRAM (eDRAM) technology is being considered as a strong alternative to conventional SRAM for use in on-chip memories. Memory cells designed using eDRAM technology in addition to being logic-compatible, are variation tolerant and immune to noise present at low supply voltages. However, two major causes of concern(More)
Memory circuits are playing a key role in complex multicore systems with both data and instructions storage and mailbox communication functions. There is a general concern that conventional SRAM cell based on the 6T structure could exhibit serious limitations in future CMOS technologies due to the instability caused by transistor mismatching as well as for(More)
With the growing importance of parametric (process and environmental) variations in advanced technologies, it has become a serious challenge to design reliable, fast and low-power embedded memories. Adopting a variation-aware design paradigm requires a holistic perspective of memory-wide metrics such as yield, power and performance. However, accurate(More)
A new approach to the design of decentralised controllers, using Multi-Objective Evolutionary Algorithm (MOEA), for load-frequency control of interconnected power systems with AC-DC parallel tie-lines and considering Governor Dead Band and Generation Rate Constraint nonlinearities, is proposed in this paper. The HVDC link is used as system interconnection(More)
In this paper we present a novel cluster paradigm and silicon operating system. Our approach in developing the competent cluster design revolves around an execution model to aid the execution of multiple independent applications simultaneously on the cluster, leading to cost sharing across applications. The execution model should envisage simultaneous(More)
