Direct examples

These examples are assembler code that can be run directly on a single core, as though that core was a CPU.

They are written primarily in RISCV-32 assembler. There are some exotic pseudoinstructions used such as OUTR, OUTR.S and HALT.

Exotic pseudoinstructions used:

• OUTR: sends the value of an unsigned integer from a register to some kind of console (via writing to memory location 1000)
• OUTR.S, as for OUTR, but treats the register as containing a 32-bit float
• HALT: halts the core

You can run these examples by using python run.py [name], e.g.:

python run.py sum_ints
