Parallel Issue
This instruction can be issued in parallel with the combination of one
16-bit length load instruction to the
other instructions can be issued in parallel with the Vector Search instruc-
tion. Note the following legal and illegal forms.
(r1, r0) = search r2 (LT) || r2 = [p0++p3]; /* ILLEGAL */
(r1, r0) = search r2 (LT) || r2 = [p0++]; /* LEGAL */
(r1, r0) = search r2 (LT) || r2 = [p0+]; /* LEGAL */
Example
/* Initialize Accumulators with appropriate value for the type of
search. */
r0.l=0x7fff ;
r0.h=0 ;
a0=r0 ;
a1=r0 ;
/* Initialize R2. */
r2=[p0++] ;
/* Assume P1 is initialized to the size of the vector length. */
