D950-Core
1: Modulo addressing mode is selected for AY0. AY0 is updated through the Y-
memory space modulo logic.
MX1: Modulo addressing mode for AX1
0: No modulo addressing mode for AX1 (def.)
1: Modulo addressing mode is selected for AX1. AX1 is updated through the X-
memory space modulo logic.
MX0: Modulo addressing mode for AX0
0: No modulo addressing mode for AX0 (def.)
1: Modulo addressing mode is selected for AX0. AX0 is updated through the X-
memory space modulo logic.
RND: Rounding type for ALU operation
0: Convergent rounding (def.)
1: Two’s complement rounding
ES: Extended Saturation
0: The saturation is active when a 32-bit overflow occurs (if SAT=1)
1: The saturation is active when a 40-bit overflow occurs (if SAT=1) (def.)
SAT: Saturation
0: ALU is not in saturated mode (def.)
1: ALU is in saturated mode
I:
Integer Product
0: Product is in fractional format (if signed * signed, one bit is shifted left before storing
the result into P register) (def.)
1: Product is in integer format (no shift and direct transfer into P register)
SR: Right side operand type (only used for product calculation and division)
0: Right side operand is unsigned
1: Right side operand is signed (def.)
SL: Left side multiplicand type (only used for product calculation)
0: Left side multiplicand is unsigned
1: Left side multiplicand is signed (def.)
LR: Right side long data
0: Normal 16-bit data mode (def.)
