[Th007] Citation: P. Bhatti, 'The SCVMS: A Single Chip Velocity Measurement System for Optical Shaft Encoders,'
MSEE Thesis, University of Washington, Department of Electrical Engineering, August 1993.
Abstract
The SCVMS provides a new hardware-based approach to velocity
measurement for optical shaft encoders. The design incorporates
features which give accurate velocity readings over a large range of
velocities (200,000 to 0.5 transitions per second). The design is
implemented in a single chip Field-Programmable-Gate Array (FPGA),
resulting in low cost, low chip-count, and user reconfigurability.
Since this design is implemented in hardware, a significant reduction
in computing requirements is realized as compared to traditional
software-based velocity measurement methods. The design is well suited
for use in motion control systems and robots for industrial and
biomedical applications.
