It has a stack-based architecture where most of the operations are done on the top elements of the stack. The instruction set consists of 17 14-bit instructions optimized for framing and driving software code. ASH1 communicates with the main processing unit (Master CPU) through a wishbone bus. It has been proven reliably at 50 MHz in an Altera Cyclone II FPGA device. With around 1400 FPGA slices and a maximum clock frequency of 90 MHz, ASH1 could make a good substitute for big USB IP Cores. Future work includes making ASH1 MAC Ethernet capable and USB2 compatible. © 2015 IEEE.
