The N.I.G.E. Machine: an FPGA based micro-computer system for prototyping experimental scienti c hardware
نویسنده
چکیده
This paper describes the N.I.G.E. Machine, a user-expandable micro-computer system that runs on an FPGA development board and is designed speci cally for the rapid prototyping of experimental scienti c hardware or other devices. The key components of the system include a stack-based softcore CPU optimized for embedded control, a FORTH software environment, and a exible digital logic layer that interfaces the micro-computer components with the external environment. The system has been demonstrated on a Digilent Nexys 2 development board and in an example scienti c experiment involving a light source and sensor.

Self authentication path insertion in FPGA-based design flow for tamper-resistant purpose
FPGA platforms have been widely used in many modern digital applications due to their low prototyping cost, short time-to-market and flexibility. Field-programmability of FPGA bitstream has made it as a flexible and easy-to-use platform. However, access to bitstream degraded the security of FPGA IPs because there is no efficient method to authenticate the originality of bitstream by the FPGA pr...
