In many computers floating point arithmetic operations are performed by subprograms: software packages in the case of most small computers, and micro-progr... JA Field - IEEE Computer Society 被引量: 9发表: 1969年 Arithmetic shift operators Verilog-1995 provides two simple shift operators: The >...
Arithmetic Logic Unit is a part of a digital computer that implements arithmetic, logic, shift and transfer micro- operations. CMOS technique is the basic and standard technique generally uses to design such type of digital circuit but the new design technique at the transistor level that shows ...
arithmetic circuitsBarrel shifter is an integral component of processor datapaths in computing systems since it can shift and rotate multiple bits in a ... S Kotiyal,H Thapliyal - 《Journal of Circuits Systems & Computers》 被引量: 6发表: 2016年 Architectural Tradeoffs in the Design of Barrel...
one of the basic units of electronic digital computers in which arithmetic and logical operations on numbers are performed directly. The performance of any arithmetic or logical operation in the unit is reduced, essentially, to a series of elementary operations, or microoperations. These include the...
Multiplication can be speeded up by using multiplier recoding of binary numbers into {−2,−1,0,+1,+2}, which results in more efficient multiplication: a single bit shift and complementation if negative. In effect this is base-4 arithmetic and the number of multiplications is halved. Carr...
c) a controlling unit responsive to the micro-instruction code sequence and operative to produce a plurality of controlling signals and to shift a busy signal between an active level and an inactive level so as to cause the central processing unit to enter a waiting state and to be recovered...
We are now in a position to answer the question, Does it matter if the basic arithmetic operations introduce a little more rounding error than necessary? The answer is that it does matter, because accurate basic operations enable us to prove that formulas are "correct" in the sense they ...
1b). It is critical to design these electrodes in a configuration where the same level of frequency shift can be achieved with any case of single high input. Figure 1c illustrates the simulation results for the optimized configuration. At any high input, the level of resonance frequency shift...
An arithmetic processing unit is disclosed that can perform multiply operations, addition operations, or a combination thereof. The arithmetic processing unit can operate in two mod
A data processor which is adapted for microprogrammed operation has a control store includes an ALU and condition code control unit for controlling operations performed by an arithmetic-logic unit within the execution unit of the data processor and for controlling the setting of the condition code ...
