Parallel overloaded CDMA crossbar for network on chip

Nanocavity crossbar arrays for parallel electrochemical sensing on a chip

We introduce a novel device for the mapping of redox-active compounds at high spatial resolution based on a crossbar electrode architecture. The sensor array is formed by two sets of 16 parallel band electrodes that are arranged perpendicular to each other on the wafer surface. At each intersection, the crossing bars are separated by a ca. 65 nm high nanocavity, which is stabilized by the surro...

A CDMA Based Scalable Hierarchical Architecture for Network- On-Chip

A Scalable hierarchical architecture based Code-Division Multiple Access (CDMA) is proposed for high performance Network-on-Chip (NoC). This hierarchical architecture provides the integration of a large number of IPs in a single on-chip system. The network encoding and decoding schemes for CDMA transmission are provided. The proposed CDMA NoC architecture is compared to the conventional archite...

Systematic Customization of On-Chip Crossbar Interconnects

In this paper, we present a systematic design and implementation of reconfigurable interconnects on demand. The proposed on-chip interconnection network provides identical physical topologies to logical topologies for given applications. The network has been implemented with parameterized switches, dynamically multiplexed by a traffic controller. Considering practical media applications, a mult...

Separability and Gain Control for Overloaded CDMA

In overloaded CDMA systems the high correlation among users’ signatures determines an overall performace that can be quite poor even for the optimal ML receiver. The geometric properties of signatures affect users’ separability, a condition that is necessary for achieving asymptotic efficiency. In this paper we establish gaussian separability conditions and propose an algorithm for the design o...
