The ARM6 along with its coprocessor (FPU) were used to do 3rd order regressions (cubic-spline) on stored convergence coefficients and fundamental waveforms. The results were then transmitted to an in-line processor which interpolated the data in the horizontal and vertical directions and generated correction waveforms through interpolative D/As. Horizontal frequencies from 15 to 70 KHz were supported for all types of video sources.
• Developed software compression/decompression modules for 24 bit video (moving JPEG, intra/inter frame coding using RLE) and 16 bit audio (ADPCM) stored on random access media (hard drive, etc.).
