Universal Optical Spatial Mode Transformer
Description and Need Designing optical systems for complex matrix transformations is a mathematically slow and challenging process. Existing solutions are often bulky, limited to specific transformations, and require intensive optimization procedures. There is a market need for a compact method to realize any desired linear operator or matrix to manipulate light. This technology addresses these […] Read More >
Peak-to-Average Power Ratio (PAPR) Reduction for High-Speed Communications
Description and Need Modern data communication demands ever-increasing transmission rates, with current standards targeting 100 Gbps to 400 Gbps. As symbol rates rise, intersymbol interference (ISI) causes the Peak-to-Average Power Ratio (PAPR) at the receiver to increase significantly, sometimes exceeding 10 dB. High PAPR requires receivers with a large dynamic range, leading to higher circuit […] Read More >
Energy Harvesting Module and Low Power Rectifier Circuit
RADIO frequency (RF) energy harvesting has garnered much interest in recent years as our lives have become more connected. Whether it be smart homes, industry 4.0, wearables or sport-tech; objects which were once inanimate are brought to life with electronics such as sensors, and low-power transceivers. This evolution of ‘things’ is commonly referred to as […] Read More >
Caches With Many Ways: 16-way Associativity for the Price of 2-way Associativity
Cache design must meet many conflicting demands: high hit rates, low cost, low power, low latency and high throughput. We propose a novel cache design for 16-way associativity with cost and power consumption like 2-way associativity. UNMET NEED We propose a novel cache design with the following features: • High effective cache capacity • Misses […] Read More >
Hardware Accelerators for Data Structures
We present the first parallel architecture for a dynamic data-structure for approximate membership (i.e., a filter). The dynamic filter supports insertions, deletions, and approximate membership queries. Our architecture borrows techniques from PRAM emulation to parallelize filters based on two levels of fingerprints. A key component in the architecture is a special-purpose wide-word processor we designed […] Read More >
Hardware Accelerators for Data Structures
We developed the first parallel architecture for a dynamic data-structure for approximate membership (i.e., a Bloom filter that also supports deletions). UNMET NEED The filter architecture supports multiple operations per cycle while preserving sequential order with a fixed and stable throughput that does not depend on the type of operations, the workload, or how populated […] Read More >
An On-Chip Sub-THz Scalable Beam Steering Antenna Array
We present a novel way of distributing signal to an antenna array without the use of power dividers. In our proposed method, we use the leaked fundamental from a non-linear harmonic generator circuit as an input to drive the next element in the chain. As a proof of concept, we show this distribution method at […] Read More >
