    • A method and apparatus is disclosed that uses an arithmetic circuit for adding numbers represented in a redundant form to also subtract numbers received in redundant form, including numbers received from a bypass circuit. A non-propagative comparator circuit is then used to compare a given value with a result from the arithmetic circuit to determine if the result is equal to the given value. All of the operations described above can be accomplished without propagating carry signals throughout the circuitry. The method includes generating a complemented redundant form of at least one number supplied to the arithmetic circuit in redundant form. It also includes providing adjustment input to the arithmetic circuit to augment a result produced through the arithmetic circuit. This adjustment causes the arithmetic circuit to generate a valid outcome in redundant form as a result of a subtraction operation if the arithmetic oepration is subtraction. Then the result is compared to a given value using a non-propagative comparator to determine equality or inequality of the result to the given value.
    • 公开了一种方法和装置,其使用运算电路来添加以冗余形式表示的数字,还可以减去以冗余形式接收的数字,包括从旁路电路接收的数字。 然后使用非传播比较器电路将给定值与运算电路的结果进行比较,以确定结果是否等于给定值。 可以在整个电路中不传播进位信号来实现上述所有操作。 该方法包括以冗余的形式生成提供给运算电路的至少一个数的补码冗余形式。 它还包括向算术电路提供调整输入以增加通过运算电路产生的结果。 如果算术运算是减法运算,则该调整将使运算电路产生冗余形式的有效结果作为减法运算的结果。 然后将结果与使用非传播比较器的给定值进行比较,以确定结果与给定值的相等或不等式。
