An energy-efficient fast array multiplier is proposed and designed. The operates in a left-to-right mode enabling full overlap between reduction of partial products carry-save form the final addition producing product. design based on carry-free (LRCF) multiplier. It differs from LRCF much smaller on-the-fly conversion circuit O(n) size use radix-4 adders conversion. new converter produces most-significant half product during process. eliminates part adder. least-significant obtained with...

A mixed radix algorithm for the in-place fast Fourier transform (FFT), which is broadly used in most embedded signal processing fields, can be explicitly expressed by an iterative equation based on Cooley-Tukey algorithm. The expression applied to either decimation-in-time (DIT) or decimation-in-frequency (DIF) FFTs with ordered inputs. For many newly emerging low power portable computing applications, such as mobile high definition video compressing, and accurate satellite location, etc.,...

With the gradual development of virtual reality (VR) technology, users have increasingly higher demand for system interaction. The human-computer interaction (HMI) by means data glove is a widely used in current days. In this paper, type single-chip microcomputer based low cost designed figure posture acquisition. Also, programmable control hand model simulation. And they are building basic HMI system. terms hardware, adopts as core processing and collects, processes transmits together with...

To reduce the computational complexity, decrease hardware resource consumption, and make it practicable, we propose a novel coordinate transformation based low-complexity Least squares (LS) algorithm. The positive integral variable is set as reference coefficients are transformed to be constant. fitting polynomial in system can easily realized with lower complexity. achieve curve original system, needed. Compared conventional LS fitting, our implementation results show that proposed...

An energy efficient truncated inner product unit is proposed in this paper. The pipelined and processes the m pairs of n-bit operands serial, so that only one required it can be reused each recurrence. Truncated produced no accumulation needed for lower part. array reduction bit-level to improve throughput reduce initial delay. A two-level [4:2] adder accumulate redundant vectors with non-uniform input arrival. compared other units using fully merged arithmetic, partially arithmetic counter...

A radix-4 energy efficient carry-free truncated multiplier is proposed and designed based on a linear array left-to-right (LRCF) [1]-[3].

A new alumina-magnesia micro powder (AMMP) consisting of γ-Al 2 O 3 and periclase was utilized to replace α-Al magnesia prepare Al -MgO (spinel-forming) castable. And the effect AMMP addition (0~9.9wt.%) on permanent linear change (PLC), apparent porosity, microstructure slag resistance were analyzed by XRD, SEM EDS as well FactSage® thermal-chemical software. The results indicated that 3.3~6.6wt% significantly reduced PLC, due improved sintering low theoretical volume expansion in situ...

Effects of spinel powder on the fracture behavior and mechanical properties lightweight magnesia-based refractories were investigated by wedge splitting test (WST) with digital image correlation acoustic emission (AE) methods. With addition powder, magnesia showed a higher cold compressive strength compared pure refractories. From WST, increased specific energy characteristic length refractories, which improved crack propagation resistance. The tortuosity main ratio along aggregates/matrix...
