one the challenging in hardware performance is to designing a high speed calculating unit. the higher of calculations speeds in a computer system  will be pointed out in terms of performance. as a result, designing a high speed calculating unit is of utmost importance. in this paper, we start design whit this knowledge that one multiplier made of several adder and one divider made of several su...

Most memory devices store and retrieve data by addressing specific memory locations. As a result, this path often becomes the limiting factor for systems that rely on fast memory accesses. The time required to find an item stored in memory can be reduced considerably if the item can be identified for access by its content rather than by its address. A memory that is accessed in this way is call...

A Content Addressable Memory (CAM) is hardware search engine in a memory unit that can perform a single clock cycle search operation. Content Addressable Memory is mostly used with the static RAM with the comparison unit to compare data in a single clock cycle leads to more power consumption. This paper proposes a Content Addressable Memory using a NAND cell structure with the comparison unit a...

-Memristor is the fourth fundamental passive element after resistor, inductor and capacitor. Memristor is memory resistor which is two terminal device. This semiconductor device is statistically proved by a student in china Leon Chua in 1971. And discovered by scientist. R.Stanley Williams and its team in April 30,2008 in lab of HP. It consist a semiconductor of titanium dioxide in which one ha...

This paper compares the performance of a number of such high capacity models, with respect to training time, attractor performance and the stability of stored patterns. The work has two goals. First, to classify the models in question using the method developed by Abbott [1]. Second, to evaluate the models against a consistent set of criteria in order to ascertain which of them gives the best b...

Memristors, Flash, and related nonvolatile analog device technologies offer in-memory computing structures operating in the domain, such as accelerating linear matrix operations array structures. These take advantage of tunability large dynamic range. At other side, content addressable memories (CAM) are fast digital lookup tables which effectively perform nonlinear Boolean logic return a match...

This paper presents a method to realize index generation functions using multiple Index Generation Units (IGUs). The architecture implements index generation functions more efficiently than a single IGU when the number of registered vectors is very large. This paper proves that independent linear transformations are necessary in IGUs for efficient realization. Experimental results confirm this ...

In the conventional content-addressable memory (CAM), equal power is consumed to determine if a stored word is matched to a search word or mismatched, independent of the number of mismatched bits. This paper presents a match-line (ML) sensing scheme that allocates less power to match decisions involving a larger number of mismatched bits. Since the majority of CAM words are mismatched, this sch...
