Trait for a vector register file where VLEN=128, ELEN=128. Data is stored in TElem, which can be plain integers or a SafeTaggedCap (which implicitly adds 1-bit)

Required methods

fn load_vreg_elem(
    &self,
    eew: Sew,
    vd_base: u8,
    idx_from_base: u32
) -> Result<TElem>[src]

Load a value from an element in a vertex register group, with specified EEW Requires the type of the value to store matches the EEW.

Example: if EEW=32bits, VLEN=128bits (4 32-bit elements per register), vd = 3, idx = 5, the actual vd = 3 + (idx_from_base / 4) = 4, and the actual idx = idx_from_base % 4 = 1. this would return v4[64:32] (element 1 of v4)

fn load_vreg_elem_int(
    &self,
    eew: Sew,
    vd_base: u8,
    idx_from_base: u32
) -> Result<u128>[src]

fn store_vreg_elem(
    &mut self,
    eew: Sew,
    vd_base: u8,
    idx_from_base: u32,
    val: TElem
) -> Result<()>[src]

Store a value in an element in a vertex register group, with specified EEW. Requires the type of the value to store matches the EEW.

Example: if EEW=32bits, VLEN=128bits (4 32-bit elements per register), vd_base = 3, idx_from_base = 5, the actual vd = 3 + (idx_from_base / 4) = 4, and the actual idx = idx_from_base % 4 = 1. This would store val into v4[64:32] (element 1 of v4)

fn store_vreg_elem_int(
    &mut self,
    eew: Sew,
    vd_base: u8,
    idx_from_base: u32,
    val: u128
) -> Result<()>[src]

fn load_vreg(&mut self, vs: u8) -> Result<TElem>[src]

fn load_vreg_int(&mut self, vs: u8) -> Result<u128>[src]

fn store_vreg(&mut self, vs: u8, val: TElem) -> Result<()>[src]

fn store_vreg_int(&mut self, vs: u8, val: u128) -> Result<()>[src]

fn seg_masked_out(&self, vm: bool, i: u32) -> bool[src]

Returns true if the mask is enabled and element i has been masked out, e.g. that it should not be touched.
