DP_SHIFT(3)

NAME
DP_SHIFT - Barrel Shifter

SYNOPSYS
#include  <fpgen.h>
void  DP_SHIFT(
    char *InstName,  /*             Instance name            */
    char *BusI0   ,  /*  IN              Shift number   DATA */
    char *BusSh   ,  /*  IN              Shift mode     CTRL */
    char *BusI1   ,  /*  IN   Operand to shift input    DATA */
    char *BusO    ,  /* OUT      Direct result output   DATA */
               EOL);

DESCRIPTION
    DP_SHIFT creates a barrel shifter and then instanciates it with the name InstName. The shifter bit-size is the full wide of the current data-path, set by the previous call to the function DP_DEFLOFIG.
    The three bit wide bus signal BusSh select which shift operation to perform :
    -    BusSh[0]    (ext)    :    When high the sign of the shifted
operand is extended.
    -    BusSh[1]    (rot)    :    When high the shift perform a rotate
operation, no rotate othewise.
    -    BusSh[2]    (left)    :    When high the direction of the shift
is left, else it is rigth.
    The environment variable MBK_CATA_LIB have to contain an additionnal library path when using this macro-function, see fpgen(1) for more details.

CHARACTERISTICS
Operator wide    :    Depends on the data-path wide.

EXAMPLE
DP_SHIFT("shift_instance0", "shift_value[4:0]" ,
                             "shift_mode[2:0]" ,
                             "shift_oper[31:0]",
                           "shift_output[31:0]", EOL);
