REV

MIN-MAX rule evaluation

Find smallest rule input (MIN).

Store to rule outputs unless fuzzy output is already larger

(MAX).

For rule weights see REVW.

Each rule input is an 8-bit offset from the base address in Y.

Each rule output is an 8-bit offset from the base address in Y.

$FE separates rule inputs from rule outputs. $FF terminates

the rule list.

REV may be interrupted.

REVW

MIN-MAX rule evaluation

Find smallest rule input (MIN),

Store to rule outputs unless fuzzy output is already larger

(MAX).

Rule weights supported, optional.

Each rule input is the 16-bit address of a fuzzy input. Each rule

output is the 16-bit address of a fuzzy output. The value $FFFE

separates rule inputs from rule outputs. $FFFF terminates the

rule list.

REVW may be interrupted.
