Magnetic skyrmions are promising candidates for logic-in-memory applications, intrinsically merging high density non-volatile data storage with computing capabilities, owing to their nanoscale size, fast motion, and mutual repulsions. However, concepts proposed so far suffer from reliability issues as well inefficient conversion of magnetic information electrical signals. In this paper, we prop...

In order to communicate with a PLC (Programmable Logic Controller) flexibly and freely, a data communication model based on the PLC's free port is designed. In the structure of the model, a distributed data communication environment is constructed by using Ethernet and serial adapters. In the communication algorithm, a method of queuebuffer for multi-threaded is used to improve the real-time of...

Modern reconfigurable systems contain 100,000+ programmable logic elements. In order to program these devices, we must rely on system level design techniques to manage the complexity and increase the efficiency of the designer. In this paper, we present a physically aware system level design flow for mapping high level application specifications to programmable logic. In particular, we study th...

The proposed reactive real{time programming system is a new approach to implement complex distributed heterogeneous real-time applications. It is based on the notion of distributed multi{agent systems. The whole control task is decomposed top down into small execution units, called agents which communicate by sending and executing contracts and are speciied in a hardware independent language ba...

A unique family of high-speed, microprogrammable asyn-chronous controller (MAC) modules is described in this correspondence.Each MAC module consists of two fundamental mode machines thatcommunicate by means of a handshake interface that permits it to bedriven by any programmable logic device including ROM’s. Any statemachine controller design@ with a MAC module will operate ...

Field-programmable gate arrays (FPGA’s) are now widely used for the implementation of digital systems, and many commercial architectures are available. Although the literature and data books contain detailed descriptions of these architectures, there is very little information on how the high-level architecture was chosen, and no information on the circuitlevel or physical design of the devices...

This paper describes an efficient hardware implementation of a new technique for interfacing the data exchange between the microprocessor-based systems and the external devices. This technique, based on the use of software/hardware system and a reduced physical address, enlarges the interfacing capacity of the microprocessor-based systems, uses the Direct Memory Access (DMA) to increases the fr...
