MannaChip

Introduction:

Manna was the miraculous food provided by God requiring no effort on behalf of the Israelites. In a similar vein, the MannaChip processor delivers groundbreaking performance, necessitating minimal intervention on the developer's or user's part.

Just as "man does not live by bread alone, but by every word that proceeds from the mouth of God," this chip thrives on every instruction word you provide. It's not just about raw computational power, but the synergy between user input and hardware optimization.

TOPMODULE=mkTop make v_compile to generate verilog. The generated verilog can be found in the verilog_RTL/ folder.

Dependencies

You'll need to install:

1. Yosys at git commit: 7ce5011c24b
2. nextpnr-0.4-36-gc8406b71
3. PrjTrellis at git commit: 1.2.1-22-g35f5aff
4. openFPGALoader

Programming the ULX3S

make fpga
# You may need the following line to set your screen device config
# to one parity and one stop bit. Tested working on MacOS, should
# work on Linux.
stty -f /dev/tty.usbserial-K00027 -cstopb -parenb
screen /dev/tty.usbserial-K00027 9600
