IXMAX
Find Maximum Index
IXMAX.U
Find Maximum Index (unsigned)
Description
Enables a search of maximum value and its related index in a vector of 16-bit signed (IXMAX) or unsigned
(IXMAX.U) values.
The IXMAX and IXMAX.U instructions are not available in the TriCore 1.2 Architecture.
For all operations:
• E[d][15:0] Working index.
• E[d][31:16] Current index of maximum.
• E[d][47:32] Current value of maximum.
• E[d][63:48] 00
H
.
• D[b][15:0] First compare value.
• D[b][31:16] Second compare value.
• E[c][15:0] Update working index.
• E[c][31:16] Update index of maximum.
• E[c][47:32] Update value of maximum.
• E[c][63:48] 00

IXMAX.UE[c], E[d], D[b] (RRR)
For IXMAX.U, the comparison is on unsigned numbers.
E[c][15:0] = E[d][15:0] + 2;
E[c][63:48] = 00
