xyzzy is a program for the Nintendo Wii which will read a console s OTP key storage and dump out the private encryption keys to screen and to SD card. This is useful information in case your Wii ever gets bricked and you need to re-initialize the FIRMWARE.
The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of FIRMWARE [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.
