In order to accomplish this, it was necessary to: 1) create programmed to act as individual low level • It was designed specifically to work and embed a BIOS into static ROM and 2) load the compiled hardware onto the logic devices and gates. with the x86 instruction set used by FPGA device. Once completed, an x86-based operating system, such as MS-DOS the Intel 8086 microprocessor. 6.22, was installed as a proof-of-concept demonstrating that the implemented • By configuring the logic elements to work processor worked. together, large and complex devices can be • The operating system came created (for example, an Intel 8086 Altera DE0 FPGA prepackaged with software which microprocessor).

QBASIC, a prepackaged IDE • Compile hardware description for the Intel 8086 and interpreter for the BASIC programming language. - The x86 16-bit based processor was compiled using the Quartus II IDE for Verilog; this included all of the necessary components to create the processor such as: the ALU, Register Memory, VGA Drivers, Intel 8086 silicon die - the hardware for this and PS2 Device Drivers. design features over 20,000 transistors • Load hardware to FPGA - The compiled hardware description was then loaded onto the FPGA by using Active Serial programming which saves the description to the on-board flash memory.
