Example #1

File: isa.py Project: cfbolz/pydgin

def execute_lbu(s, inst):
    addr = trim(s.rf[inst.rs()] + sext(inst.imm()))
    s.rf[inst.rt()] = s.mem.read(addr, 1)
    s.pc += 4

Example #2

File: isa.py Project: cfbolz/pydgin

def execute_sb(s, inst):
    addr = trim(s.rf[inst.rs()] + sext(inst.imm()))
    s.mem.write(addr, 1, s.rf[inst.rt()])
    s.pc += 4

Example #3

File: isa.py Project: cfbolz/pydgin

def execute_bne(s, inst):
    if s.rf[inst.rs()] != s.rf[inst.rt()]:
        s.pc = s.pc + 4 + (signed(sext(inst.imm())) << 2)
    else:
        s.pc += 4

Example #4

File: isa.py Project: cfbolz/pydgin
