Function Documentation

get_field()

static uint32_t get_field ( uint32_t  val, uint32_t  end, uint32_t  start  )

inlinestatic

extract the specified bit field from a 32 bit unsigned integer.

Parameters

val	input from which the bitfield is extracted
end	upper bit index of the bitfield
start	lower bit index of the bitfield

Returns

extracted bit field, right shifted by start bits.

set_field()

static uint32_t set_field ( uint32_t  tgt, uint32_t  end, uint32_t  start, uint32_t  val  )

inlinestatic

set the specified bit field from a 32 bit unsigned integer to provided value

Parameters

tgt	input in which the bitfield is to be set
end	upper bit index of the bitfield
start	lower bit index of the bitfield
val	value to which the bit field is to be set.

Returns

input value with bitfield updated as specified.

get_mask()

static uint32_t get_mask ( uint32_t  end, uint32_t  start  )

inlinestatic

Generate a mask for the give bit field [end:start].

All the bits between the two specified bit indices including the specified indices are set to 1. Rest of the bits are set to zero.

Parameters

end	upper bit index of the mask
start	lower bit index of the mask

Returns

generated mask
