Record #7670
Product Family: Hardware
Product Line: R3000
Product Part: R3320
Product Version: XPLA2
Problem Title:
XPLA2: Usefulness of the hardwired XOR.
Problem Description:
Urgency: Standard
General Description: Why is the hardwired XOR useful in XPLA2 devices?
Solution 1:
An XOR of N signals takes 2^(N-1) product terms to implement. Therefore,
utilizing the hardware XOR gate can significantly reduce the number of
product terms required by the design.
