Kofi worked for the Robotics research group. He covered a brief history of computer processors, which included:
1970s - Semi-conductors
1980s - DRAM
1990s - Micro processors
2000s - DPS, the technology of FOCUS
The lecture mentioned the increase in chip speed, the speed of which hit a limit at 2Gz, as 4Gz was eventually deemed unfeasible. This was announced on October 4th 2004 by Intel when project Tejas, the 7Gz chip, failed due to overheating and melting of the chip.
This led to multi-core processor, which have a 30% -70% improvement on single core chips of the same speed. FPGA is a parallels approach to processing.
One project Kofi was working with using these processors was a smart camera, which tracks movement by locating new pixels in the current frame from the stored background image.
