`Port music synthesis algorithms in assembly language for the
`ARM7/TDMI processor, following ARM’s C calling conventions. This
`project ran under very tight time constraints, cost only 2/3 of the projected
`budget, and resulted in code that runs much faster than the original
`implementation.

`Implement in C and Analog Devices Sharc 21161 assembly language a
`novel scheme based on their patented technology to improve the
`perceived loudness of audio signals sent over broadcast. Provide a
`subcontractor who made significant contributions to filter design.
`
`Client: Analog Devices
`Location: Wilmington, MA (Ray Stata Technology Center)
`After an on-site visit to learn more about the technology and meet the
`team, I made recommendations on changes to architecture for a new
`version of an idiosyncratic signal processing chip. I also provided code
`examples for the new architecture.
