Kodak acquired Applied Science Fiction in March of 2003. Continued previous work on vector math and imaging libraries. Developed code to test the FPIM (Film Processing and Imaging, formerly known as the Digital Film Processor) hardware before final machine assembly. Digital Dust [Windows, C++, tVec]Developed an algorithm and code to remove dust and specks from digital image scans. Detected areas of high detail verses areas of uniformity and only applied dust removal in uniform regions. Dust and specks were effectively removed without blurring the image.Image Station and Field Replaceable Unit Tests [Windows, C++, MFC]Developed an application suite to test the FPIM’s robotic and imaging components for use in both assembly line and test bench scenarios.

Developed vector and image mathematical libraries and data paths for the Digital Film Processor, a system designed to digitally render images from undeveloped 35mm film. Digital Film Processor Image Path and Image Library [Windows, Linux, C++, tVec]Developed DFP image rendering and noise processing routines under the direction of ASF’s chief scientist, Dr. Albert Edgar. Quad-G4 Processor Daughter Card OS, Libraries and Utilities [Windows, Linux, C++, MFC]Co-Developed an embedded processor operating system for an in-house quad-G4 processor daughter card. Each processor had complete independent functionality with direct (DMA) memory-to-memory data transfer. Utilities included a Windows based monitoring and management application that could control or examine all daughter processors independently or in groups.tVec Vector Library [Windows, Linux, Mac OS, C, AltiVec, SIMD]Co-wrote and managed the development of an extensive and highly optimized vector float math library of ~100 functions. Implemented in scalar and AltiVec/SIMD intrinsics, the library detected processor level and automatically reassigned function pointers accordingly.

Developed borehole equipment modeling and property editing software for the GeoFrame System Components group.Graphical Borehole Equipment Modeler [Windows NT, VC++ 6.0,Visio, MFC, COM]Designed both a Visio template and an Open Inventor based application to graphically model borehole equipment as described in a borehole equipment database. Borehole Equipment Catalog [Windows NT, VC++ 6.0, Active X, MFC, Ole]Developed a catalog of borehole equipment, hierarchically categorized by job/equipment type. The catalog defined connectivity and containment rules for borehole modeling and acted as a drag source for common borehole equipment.

Developed and supported logic simulation tools for the Power, Power2 and PowerPC design projects. Design Logic Synthesis and Model Build [AIX, C/C++]Architected logic synthesis and optimization systems for both compiled code and event driven cycle simulators. Logic synthesis consisted of translating a box/net graph of compiled DSL, Verilog or VHDL into logic gates for a target simulator. For the compiled code simulators, this required generating executable RISC assembly to represent models. Optimizations included standard boolean logic reductions, redundancy removal, gate compaction, zero sink cone removal and assembly instruction reordering and register leveling.Graphical Logic Database Browser [AIX, Motif, C++]Developed an application to graphically display the contents of a logic design database in a levelized box/net graph. Provided trace functions and back annotation of design data such as timing and AET values. Client/Server Distributed Simulation Environment [AIX, Motif, C] Worked on a team to produce a client/server distributed simulation environment and related data and server management utilities. Server featured multiple job queues, CPU usage monitoring, job tracking, and priority job scheduling. Developed a Motif application to monitor and administer jobs, queues and machines in the distributed simulation environment.
