Cmos Smart Camera With Focal Plane Neighborhood-Parallel Image Processing, Joseph A. Schmitz

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

A neighbhorhood-based smart camera architecture is designed and implemented in a 0.13 μm CMOS technology. Each 8 × 8 region of pixels contains a small processor with local memory, which are tiled to form a full-resolution camera. Each processor operates in parallel, enabling high-speed image processing suitable for tracking and recognition tasks. The architecture features the programming flexibility of designs us- ing chip-level and row-level processors while preserving the scalability of pixel-parallel processing elements. The neighborhood processors are implemented physically be- tween the pixel photodiodes, creating multiple design challenges that are discussed in detail.

Cad Tools For Synthesis Of Sleep Convention Logic, Parviz Palangpour

Graduate Theses and Dissertations

This dissertation proposes an automated flow for the Sleep Convention Logic (SCL) asynchronous design style. The proposed flow synthesizes synchronous RTL into an SCL netlist. The flow utilizes commercial design tools, while supplementing missing functionality using custom tools. A method for determining the performance bottleneck in an SCL design is proposed. A constraint-driven method to increase the performance of linear SCL pipelines is proposed. Several enhancements to SCL are proposed, including techniques to reduce the number of registers and total sleep capacitance in an SCL design.
