Implementations

impl Rv64imvXCheriProcessor

pub fn new(
    start_pc: u64,
    mem: CheriAggregateMemory,
    mode: CheriExecMode
) -> (Rv64imvXCheriProcessor, Rv64imvXCheriProcessorModules)

Create a new processor and vector unit which operates on given memory.

Arguments

• mem - The memory the processor should hold. Currently a value, not a reference.

fn zicsr_conn<'a, 'b>(&'a mut self, rvv: &'a mut Rv64Cheriv) -> Zicsr64Conn<'b> where
    'a: 'b, 

fn xcheri64_conn<'a, 'b>(&'a mut self, mode: CheriExecMode) -> XCheri64Conn<'b> where
    'a: 'b, 

fn process_inst(
    &mut self,
    mods: &mut Rv64imvXCheriProcessorModules,
    inst_bits: u32,
    opcode: Opcode,
    inst: InstructionBits
) -> Result<Cc128Cap>

Process an instruction, returning the new PC value or any execution error

Arguments

• v_unit - The associated vector unit, which will execute vector instructions if they are found.
• inst_bits - The raw instruction bits
• opcode - The major opcode of the decoded instruction
• inst - The fields of the decoded instruction

Trait Implementations

impl Processor<Rv64imvXCheriProcessorModules> for Rv64imvXCheriProcessor

fn reset(&mut self, _mods: &mut Rv64imvXCheriProcessorModules)

Reset the processor and associated vector unit

fn exec_step(&mut self, mods: &mut Rv64imvXCheriProcessorModules) -> Result<()>

Run a fetch-decode-execute step on the processor, executing a single instruction

Arguments

• v_unit - The associated vector unit, which will execute vector instructions if they are found.

fn dump(&self, mods: &Rv64imvXCheriProcessorModules)

Dump processor and vector unit state to standard output.

fn running(&self) -> bool

fn get_io_values(&self) -> Vec<Option<u64>>
