John Thompson,
CEO, Symantec
Quick facts on the merger
Total value: $13.5 billion
Combined revenue:
$5 billion
Combined staff: 13,000 employees
By comparison: Oracle bought PeopleSoft this week for $10 billion
Main focuses: Symantec is the largest maker of PC security and antivirus software. Veritas is No. 2 in the storage software market.
Rivals: The combined company will be up against, among others, storage top dog EMC; IBM in software, hardware and services; Cisco and Juniper in network security; security specialists McAfee and Check Point; and Microsoft, as that giant edges into antivirus and antispyware activities.

US'120 Patent Description and Terms
Dear, Sir/Madam:
I have spent years in college as a Graduate, and a student colleague of a pronoun known Scientist and dear personal friend. Dr. Rastko C. Maglic is the father creator of the Operational Amplifier. Dr. Maglic classified and peered JR as a higher intellect and being a Scientist in his own rights. JR is the inventor of Selective Negation June 22, 1988. The inventor's technology existed and was tested beyond 64 bit Technology over twelve years ago, and honored by the National Institute of Standards and Technology. It describes a novel binary adder that is faster than conventional adders. This included advantages over competing products or processes on the market or in development.
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to digital electronic circuits, such as those used in general purpose computers and microprocessors and in special purpose machines. More specifically, the present invention relates to electronic circuits which are used in performing arithmetic operations on two's complement binary numbers.
BACKGROUND OF THE INVENTION
Conventional binary arithmetic circuits perform arithmetic operations, particularly subtraction and negation, in an indirect and inefficient manner. Subtraction has been performed by inverting a subtrahend number to form a one's complement of the subtrahend, adding the inverted subtrahend to a minuend number, and then incrementing the addition result. The incrementing of the addition result is typically accomplished by supplying a carry pulse to an adder when a subtraction is performed. A simple negation has been treated as a special subtraction problem with the minuend forced to equal zero. Thus, the same indirect steps are involved in obtaining a two's complement negation of an incoming number. Often, additional enabling combinatorial logic is required to selectively invert the subtrahend and to selectively apply the carry pulse when a subtraction or negation operation is required and to prevent inversion of the subtrahend and addition of a carry pulse when addition and other arithmetic operations are required.
In many situations, the indirect techniques for performing subtraction and negation operations are undesirable. These indirect techniques often require an undesirably large amount of circuit area or number of components for their implementation. Moreover, these indirect techniques often cause the propagation delay between the time when an incoming number is valid and the time when the subtraction or negation operation results are valid to be undesirably long.
SUMMARY OF THE INVENTION
Accordingly, it is an advantage of the present invention that an improved arithmetic circuit is provided.
Another advantage of the present invention is that an arithmetic circuit is provided which may be incorporated in a wide variety of applications, including arithmetic logic units (ALUs) for microprocessors or other computing circuits, add/subtract circuits, subtraction circuits, and negation circuits.
Another advantage of the present invention is that an arithmetic circuit is provided which generates a two's complement negation of an incoming number in a small amount of space and with a small amount of propagation delay.
Another advantage of the present invention is that an arithmetic circuit is provided which selectively generates a negation of an incoming number.
Another advantage of the present invention is that an arithmetic circuit is provided which selectively performs addition or subtraction operations, wherein the subtraction operations are performed in a direct manner which does not require the generation of a carry input pulse.
Another advantage of the present invention is that an arithmetic circuit is provided which may be adapted to efficiently generate negations for incoming numbers having any number of bits.
