Parameters

Parameter	Type	Required	Description
`LPM_WIDTH`	Integer	Yes	Width of the `data[]` and `result[]` ports. Any positive integer greater than 1.
`LPM_WIDTHDIST`	Integer	Yes	Width of the `distance[]` input port. The `LPM_WIDTHDIST` parameter specifies the width of the `distance` port. The values on the `distance` port normally range from 0, which is "no shift", to (`LPM_WIDTH-`1) which is the maximum meaningful shift. The typical value assigned to `LPM_WIDTHDIST` is "the smallest integer not less than log-base-2(`LPM_WIDTH`)" or `[`log-base-2(`LPM_WIDTH`)`]`. Any value on the `distance` port greater than `LPM_WIDTH`-1 results in an undefined (X) logic level.
`LPM_SHIFTTYPE`	String	No	Specifies the shifter type. Values are `"LOGICAL"`, `"ROTATE"`, `"ARITHMETIC"`, and `"UNUSED"`. If omitted, the default is `"LOGICAL"`. The sign bit is extended for `"ARITHMETIC"`. For a `"LOGICAL"` right shift, 0s are always shifted into the MSB.
LPM_PIPELINE	Integer	No	Specifies the number of clock cycles of latency associated with the`result[]`output. A value of zero (0) indicates that no latency exists, and that a purely combinational function is instantiated. The default is 0 (non-pipelined). You cannot specify a value for the`LPM_PIPELINE`parameter that is higher than`distance[]`.
