tenyr

Overview

tenyr is a 32-bit computer architecture and computing environment that focuses on simplicity of design and implementation. tenyr’s tools run on Mac, *nix, and Windows on multiple architectures. tenyr’s highly portable Verilog hardware definition has been demonstrated on a Lattice ECP5 FPGA with the ULX3S development board, and on a Xilinx Spartan6 FPGA with the Nexys3 development board.

tenyr comprises :

• an instruction set architecture (ISA)
• an implementation in FPGA hardware with device support
  • VGA text output at 64x32 resolution is supported
  • no input devices are currently implemented in hardware – help appreciated !
• tools for building software
  • assembler (tas)
  • linker (tld)
  • simulator (tsim)
• a standard library of tenyr code
• some example software, including :
  • Conway’s Game of Life (tenyr source code)
  • random snakes “screensaver” (tenyr source code – running in the simulator, running on the FPGA)
  • a recursive Fibonacci number generator

tenyr’s documentation is a wiki, and it keeps a changelog from v0.9.4 onward.
