Operation
X n
VXGATH Vector External Gather
The VXGATH instruction gathers non-contiguous elements
of the external memory vector as specified by the Y integer
vector and places them in contiguous locations in the Z real
vector The external memory address is specified in the
EABR and X registers
Syntax
EXEC VXGATH
Operation
3 4 5 10 Arithmetic Logical Instructions
VROP Vector Real Op
The VROP instruction performs one of 7 operations be-
tween corresponding elements of the X and Y real vectors
and writes the result in the corresponding place in the Z
output vector The operation to be performed is specified in
PARAM OP field

VAROP Vector Aligned Real Op
The VAROP instruction performs one of 7 operations be-
tween corresponding elements of the X and Y aligned vec-
tors and writes the result in the coresponding place in the Z
output vector The operation to be performed is specified in
PARAM OP field
Syntax
EXEC VAROP

3 4 5 11 Multiply-and-Accumulate Instructions
VRMAC Vector Real Multiply and Accumulate
The VRMAC instruction performs a convolution sum of the
X and Y real vectors The previous value of the accumulator
is used and the result stored in Z 0
