The fractional portion of the accumulated sum remains in the accumulator, such that round-off errors do not accumulate over time. The preferred adder is digital, such that this computation may be carried out to any desired level of precision. Additionally, the same design, but with a different constant, may be used to generate other intervals (e.g. for lunar mont...
: adder for , : multiplier for . The time delay of the proposed multiplier is reduced from to . For example, if the time delay of and are equal then the total time delay is approximately reduced by 30% when . Also, the proposed multiplier has the same time delay compared to the previ...
so the reduction accumulator can have typefloat. For large reductions this is unwise since single-precisionfloating pointvalues may not be able to represent partial sums with sufficient precision as explained inSection 5.1.4. However, the same type for the accumulator, the input, and the output ...

The proposed multiplier consists of a serial-serial data accumulator module and carries save adder that occupies less silicon area than the full carry save adder. In this paper we proposed model address for the 8bit 2's complement implementing the Baugh-wooley algorithm and unsigned multiplication ...
A novel multiplication architecture¿the `automultiplier¿¿ pipelines the formation of partial products and dispenses with gating in the critical sum and carry paths internal to the array, reducing the computational element to the minimum full-adder at each stage. The automultiplier is so-...
inserted into register A and printed and displayed at 60. The settings of keys 16 are taken from register A and added into the minor total accumulator by feeding a serial full adder-subtractor 300 from register A (via gates 400) and the recirculating register (via gates 200) the result dig...
A multiply-accumulate (MAC) operation computes the product of two numbers and adds the product to an accumulator. A processor may contain MAC computational hardware logic that includes a multiplier implemented in combinational logic followed by an adder and an accumulator register that stores the resu...
A parallel - serial multiplier-adder, used to be a word multiplicand and multiplier are multiplied to obtain a product, then this product with an accumulator input added. 该并行—串行乘加器包括一并行—串行乘法器和一数字串行加法器. The parallel - serial multiplier-adder includes a parallel - ...
During the first word frame, inverter 62 and signal MARK cause AND gate 21 to be disabled, so that the recirculated output to adder 18 from the second least significant bit of ACUM TERMS register 20 is zero. This effectively initializes the product accumulator to allow accurate accumulation ...
