Massively parallel CPU processes 256 shades of gray

Massively parallel CPU processes 256 shades of gray

The 1980s were a heyday for strange computer architectures; instead of the von Newmann architecture you’d find in one of today’s desktop computers or the Harvard architecture of a microcontroller, a lot of companies experimented with strange parallel designs. While not used much today, at the time these were some of the most powerful computers of their day and were used as the main research tools of the AI renaissance of the 1980s. Over at the Norwegian University of Science and Technology a huge group of students (13 members!) designed a modern take on the massively parallel computer. It’s called 256 Shades of Gray , and it processes 320×240 pixel 8-bit grayscale graphics like no microcontroller could. The idea for the project was to create an array-based parallel image processor with an architecture similar to the Goodyear MPP formerly used by NASA or the Connection Mach...
