In-Memory Hardware-Software Co-design for Image Processing
A substantial part of high energy consumption (> 60%) and large latency (> 90%) of conventional von-Neumann architectures can be attributed to the unavoidable data movement between the processor and main memory (DRAM). This is perhaps the major limiting factor for big data and machine learning applications whose usage is permeating into practically...

Clock Skewing for Area and Power Optimization of ASICs Using Differential Flipflops and Local Clocking
Synchronous logic remains the dominant design paradigm of digital systems such as Application Specific Integrated Circuits (ASICs). The conventional design of sequential circuit networks is based on the assumption that every register receives the clock signal at the same time. However, guaranteeing the simultaneity of clock arrival times in practice...

Performance and Energy Optimal DVFS, Task Migration and Active Cooling for Multi-core Processors
Multi-core processors have become the de facto standard of computing systems in all market segments: smartphones, laptops, desktops, and servers. A fundamental problem is being able to control the operation of the individual cores so as to maximize some suitably chosen measure of quality of service. Often, the primary goal in the design of any computing...

Temperature-aware Robust Controller for Multi-core Processors
The transition to multi-core processors has allowed their continued improvement within their limited power budget by using threads on multiple cores. By reducing the power per core and increasing the number of cores initially allowed, it is possible to circumvent the power wall of single core processors. Unfortunately, multi-core scaling is fast becoming...

A Robust Low Power Field Programmable Threshold Logic Gate Array
Existing complementary metal-oxide-semiconductor (CMOS) technologies are becoming obsolete because we have nearly reached the maximum capability of further miniaturizing computer chips built from modern, state-of-the-art materials. The semiconductor industry association predicts that further scaling is not sustainable and new technologies that can replace...

RRAM-Enhanced Differential Threshold Logic Gates That Are Robust For Low Voltage Operation
All digital circuits use sequences of logic gates that implement Boolean functions to store and transmit binary information. Threshold logic gates receive multiple input signals and produce a single output if the number of signals is below a hardwired threshold value, and can therefore process any Boolean function that might otherwise require multiple...

A Robust Asynchronous Scan Chain and Scanning Mechanism for Testing of Digital VLSI Circuits
Very-large-scale-integration (VLSI) is a process of creating massive integrated circuits which enables design of all integrated circuit (IC) components onto a single chip. Thousands of transistors are combined onto a single chip, necessitating highly efficient data scanning in and out of each circuit. Typically the scan-in and scan-out operations are...
