Continuous scaling of the transistor size and reduction of the operating voltage has led to a significant performance improvement of integrated circuits. Low power consumption and smaller area are the most important criteria for the fabrication of DSP systems. Static random access memories (SRAMs) consist of almost 90% of very large scale integrated (VLSI) circuits. The ever-increasing demand f...

The OR-NOT operation x _ y between two binary vectors x and y of the same length is viewed as an operation between the new and old content of a random-access memory used to increase the speed of the access to the memory. Coding procedures that allow us to recover x based on x_y are developed and connections of this model of the memory with the model of write-unidirectional memory are established.

Back-end processors have been conventionally used for speeding up of only a specific set of compute intensive functions. Such co-processors are, generally, "hardwired" and cannot be used for a new function. In this paper, we discuss the design considerations and parameters of a general purpose reconfigurable co-processor. We also propose architecture of such a co-processor and discuss its imple...

The main memory has become a power bottleneck for computer systems. To reduce the energy dissipation of main memory, the non-volatile phase-change RAM (PRAM) has emerged as one of the promising memories due to its high density and low standby power. But PRAM has its intrinsic disadvantages of long write latency and high write energy. Hence, the hybrid DRAM/PRAM main memory is proposed to provid...

Flash memory has become the most important storage media in mobile devices, and is beginning to replace hard disks in desktop systems. However, its relatively poor random write performance may cause problems in the desktop environment, which has much more complicated requirements than mobile devices. While a RAM buffer has been quite successful in hard disks to mask the low efficiency of random...

Traditionally, digital tape has been used by applications accessing the tape mostly sequentially. Applications having a random access pattern to the data are much better off storing the data on magnetic disks. Today we see new application areas, where the need for huge amounts of digital storage does not make it cost-effective to store all the data on magnetic disk. One example of such an appli...

Text is the Data, that consists of characters representing the words and symbols of human speech and usually, characters coded according to the ASCII standard, which assigns numeric values to numbers, letters, and certain symbols. Text is obviously the simplest of data type and required the learnt amount of storage in addition that text data can he made fields in a data issue that can be indexe...

This work presents several approaches for designing the memory management component of self-stabilizing operating systems. We state the requirements a memory manager should satisfy. One requirement is eventual memory hierarchy consistency among different copies of data residing in different (level of) memory devices e.g., RAM and Disk. Another requirement is stabilization preservation a conditi...

A thin client approach to mobile computing pushes as many services as possible on a remote server. However, as will be shown, technology trends indicate that an easy route to improving thin client functionality is to “thicken” the client through addition of disk storage, CPU, and RAM. Thus, thin clients will rapidly become multi-purpose thick clients. With time, users may come to consider their...

Network processors utilize a special unit for the classification of the received packets according to their characteristics. The classification of packets is currently the most processor intensive portion of network processing which has to be performed at wire speed. Currently, network processors use Content Addressable Memories (CAM), for classification of thousands of flow identifiers in ATM ...
