The 7GHz of bandwidth available in the 60GHz band offers an opportunity to achieve multi-Gb/s wireless links. For this reason, ultra-high data-rate wireless communication over the 60GHz band has gained increasing interest from both academic and industrial groups.This report first presents the design methodology for a mixed-signal DFE. The technique can be used to explore the design space and compute the power dissipation of a DFE as a function of data-rate and the number of taps (i.e. the channel characteristics).

The TerraSwarm Research Center (TSRC), announced on October 31, 2012, will be addressing the huge potential (and associated risks) of pervasive integration of smart, networked sensors and actuators into our connected world. A five-year grant is being awarded by the industry members of the Semiconductor Research Corporation (SRC) and the Defense Advanced Research Projects Agency (DARPA) as a part of the Focus Center Research Program (FCRP).

We argue that mid-level representations can bridge the gap between existing low-level models, which are incapable of capturing the structure of interactive verbs, and contemporary high-level schemes, which rely on the output of potentially brittle intermediate detectors and trackers. We develop a novel descriptor based on generic object foreground segments; our representation forms a histogram-of-gradient representation that is grounded to the frame of detected key-segments. Importantly, our method does not require objects to be identified reliably in order to compute a robust representation. We evaluate an integrated system including novel key-segment activity descriptors on a large-scale video dataset containing 48 common verbs, for which we present a comprehensive evaluation protocol. Our results con firm that a descriptor defined on mid-level primitives, operating at a higher-level than local spatio-temporal features, but at a lower-level than trajectories of detected objects, can provide a substantial improvement relative to either alone or to their combination.

Cyclops (cyclic-operations) Tensor Framework (CTF) is a distributed library for tensor contractions. CTF aims to scale high-dimensional tensor contractions such as those required in the Coupled Cluster (CC) electronic structure method to massively-parallel supercomputers. The framework preserves tensor structure by subdividing tensors cyclically, producing a regular parallel decomposition. An internal virtualization layer provides completely general mapping support while maintaining ideal load balance. The mapping framework decides on the best mapping for each tensor contraction at run-time via explicit calculations of memory usage and communication volume. CTF employs a general redistribution kernel, which transposes tensors of any dimension between arbitrary distributed layouts, yet touches each piece of data only once. Sequential symmetric contractions are reduced to matrix multiplication calls via tensor index transpositions and partial unpacking. The user-level interface elegantly expresses arbitrary-dimensional generalized tensor contractions in the form of a domain specific language. We demonstrate performance of CC with single and double excitations on BlueGene/Q and Cray XE6 supercomputers.

Cake is a coordinated, multi-resource scheduler for shared distributed storage environments with the goal of achieving both high throughput and bounded latency. Cake uses a two-level scheduling scheme to enforce high-level service-level objectives (SLOs). First-level schedulers control consumption of resources such as disk and CPU. These schedulers (1) provide mechanisms for differentiated scheduling, (2) split large requests into smaller chunks, and (3) limit the number of outstanding device requests, which together allow for effective control over multi-resource consumption within the storage system. Cake’s second-level scheduler coordinates the first-level schedulers to map high-level SLO requirements into actual scheduling parameters. These parameters are dynamically adjusted over time to enforce high-level performance specifications for changing workloads. We evaluate Cake using multiple workloads derived from real-world traces. Our results show that Cake allows application programmers to explore the latency vs. throughput trade-off by setting different high-level performance requirements on their workloads. Furthermore, we show that using Cake has concrete economic and business advantages, reducing provisioning costs by up to 50% for a consolidated workload and reducing the completion time of an analytics cycle by up to 40%.

Scaling of CMOS technology into the deep submicron regime gives rise to process variability, which in turn compromises circuit yield. One of the main sources of variability is random dopant fluctuation (RDF) in the channel. Fully Depleted Silicon on Insulator technology has been proposedas a promising alternative to bulk CMOS, due to it’s undoped channel which reduces RDF, as well as due to its better electrostatic control of the channel.

We propose a novel and inexpensive infrastructure for precise localization in non-line-of-sight wireless environments using RFID tags. The proposed system utilizes specialized tags that we term as supertags. Each supertag is an array of individual single antenna RFID tags closely spaced so as to emulate a “virtual” antenna array. Multiple such supertags are installed in a 3D environment where we are interested in localizing mobile agents equipped with an RFID reader.

An increasing number of consumer products include user interfaces that rely on touch input. While digital fabrication techniques such as 3D printing make it easier to prototype the shape of custom devices, adding interactivity to such prototypes remains a challenge for most designers. We introduce Midas, a software and hardware toolkit to support the design, fabrication, and programming of flexible capacitive touch sensors for interactive objects. With Midas, designers first define the desired shape, layout, and type of touch sensitive areas in a sensor editor interface. From this high-level specification, Midas automatically generates layout files with appropriate sensor pads and routed connections. These files are then used to fabricate sensors using digital fabrication processes, e.g. vinyl cutters and circuit board printers. Using step-by-step assembly instructions generated by Midas, designers connect these sensors to our microcontroller setup, which detects touch events. Once the prototype is assembled, designers can define interactivity  for their sensors: Midas supports both record-and-replay actions for controlling existing local applications and WebSocket-based event output for controlling novel or remote applications. In a first-use study with three participants, users successfully prototyped media players. We also demonstrate how Midas can be used to create a number of touch-sensitive interfaces.

Building Cyber-Physical Systems (CPS) involves several teams of engineers with different back- grounds. We focus on interactions between control engineers and embedded software engineers. Lack of rigorous methodologies for communication and interaction between the two groups has been recognized as an obstacle to the development of dependable and cost-effective CPS. We advocate the use of design contracts as a step towards bridging this gap. Design contracts act as a medium for communication and interaction between the control and computation/communication design problems in a CPS. The contracts provide a focal point for negotiation and for decision making.

This report presents details of the eighth six-inch baseline run, CMOS200, where a moderately complex 0.35 μm twin-well, silicided, LOCOS process was implemented. This process was based on the previous 0.35 μm six-inch run, CMOS192. CMOS200 was the start-up run in the new Marvell NanoLab, showing the ability to fabricate operational MOSFETs, after the move from the Microlab.
