A 64-bit MIPS processor running freebsd on a portable FPGA tablet

Abstract

We will demonstrate a portable FPGA tablet running a system-on-chip design featuring a 64-bit MIPS soft processor (BERI, Bluespec Extensible RISC Implementation) running the FreeBSD UNIX-derived OS. The demonstration has a graphical user interface which includes a file browser, a slide presenter, a drawing application, and a terminal with an on-screen keyboard. The system-on-chip and operating system also support DDR2 SDRAM for main memory, a capacitive touchscreen, flash, SRAM, SD card, and HDMI out. Gigabit ethernet provides an internet connection and permits SSH remote login and mounting fileservers via NFS.
