I
Barrel Shifter:
aD = aS >> IM16
aD = aS >> arM
aD = aS >> aS
Arithmetic right shift by immediate (36-bit, sign filled in); 2-cycle, 2-word.
Arithmetic right shift by
arM
(36-bit, sign filled in); 1-cycle.
Arithmetic right shift by aS (36-bit, sign filled in); 2-cycle.
aD = aS >>> IM16
aD = aS >>> arM
aD = aS >>> aS
Logical right shift by immediate (32-bit shift, 0s filled in); 2-cycle, 2-word.
Logical right shift by
arM
(32-bit shift, 0s filled in); 1-cycle.
Logical right shift by aS (32-bit shift, 0s filled in); 2-cycle.
aD = aS << IM16
Arithmetic left shift
by immediate (36-bit shift, 0s filled in); 2-cycle, 2-word.
Arithmetic left shift
by
arM
(36-bit shift, 0s filled in); 1-cycle.
Arithmetic left shift
by aS (36-bit shift, 0s filled in); 2-cycle.
aD = aS << arM
aD = aS << aS
aD = aS <<< IM16
aD = aS <<< arM
aD = aS <<< aS
Logical left shift by immediate (36-bit shift, 0s filled in); 2-cycle, 2-word.
Logical left shift by
arM
(36-bit shift, 0s filled in); 1-cycle.
Logical left shift by aS (36-bit shift, 0s filled in); 2-cycle.
Not the same as the special function arithmetic left shift. Here, the guard bits in the destination accumulator are shifted into, not sign-extended.
I
Normalization and Exponent Computation:
aD = exp(aS)
aD = norm(aS, arM)
Detect the number of redundant sign bits in accumulator; 1-cycle.
Normalize aS with respect to bit 31, with exponent in
arM
; 1-cycle.
I
Bit Field Extraction and Insertion:
aD = extracts(aS, IM16) Extraction with sign extension, field specified as immediate; 2-cycle, 2-word.
aD = extracts(aS, arM) Extraction with sign extension, field specified in
arM
; 1-cycle.
aD = extractz(aS, IM16) Extraction with zero extension, field specified as immediate; 2-cycle, 2-word.
aD = extractz(aS, arM) Extraction with zero extension, field specified in
arM
; 1-cycle.
aD = insert(aS, IM16)
aD = insert(aS, arM)
Bit field insertion, field specified as immediate; 2-cycle, 2-word.
Bit field insertion, field specified in
arM
; 2-cycle.
Note:
The bit field to be inserted or extracted is specified as follows. The width (in bits) of the field is the upper byte
of the operand (immediate or arM), and the offset from the LSB is in the lower byte.
I
Alternate Accumulator Set:
aD = aS:aa0
aD = aS:aa1
Shuffle accumulators with alternate accumulator 0 (
aa0
); 1-cycle.
Shuffle accumulators with alternate accumulator 1 (
aa1
); 1-cycle.
Note:
The alternate accumulator gets what was in aS. aD gets what was in the alternate accumulator.
