Functions
- trim ( constant source : std_logic_vector;
constant num_bits : positive := C_NUM_SOURCES) return t_irq_source
Description
Trim (cut) a given vector to fit the number of irq sources (i.e. pot. reduce width)
- fit ( constant source : std_logic_vector;
constant num_bits : positive := C_NUM_SOURCES) return std_logic_vector
Description
Fit a given vector to the number of irq sources by masking with zeros above irq width
