This paper present a method of constructing embedded system based on the hardware and software which is a center of 21th information technology. For the purpose of that, we discuss the embedded system classification and necessity also the main points which is the key when we constructing the embedded system. We discuss the embedded system modelling. The proposed hardware and software embedded system be able to contribute future advanced information technology upcoming.

This pper presents a method for constructing multiple-valued logic sequential machines based on Galois field. First, we assign all elements in GF(2**m) to bit codes using mathematical properties of GF(2**m). Then, we realized the sequencial machine circuits with and withoutm feed-back. 1) Sequential machines with feed-back are constructed by using only MUX from state-transition diagram expressing the information of sequential machines. 2) Sequential machines without feed-back are constructed by following steps. First, we assigned states in state-transition disgram to state bit codes, then obtained state function and predecessor table explaining the relationship between present states and previous states. Next, we obtained next-state function from state function and predecessor table. Finally we realized the circuit using MUX and decoder.

This paper presented a method of extracting algorithm for Edge Multiple-Valued Decision Diagrams(EMVDD), a new data structure, from Binary Decision Diagram(BDD) which is resently using in constructing the digital logic systems based on the graph theory. We discussed the function minimization method of the n-variables multiple-valued functions and showed that the algorithm had the regularity with module by which the same blocks were made concerning about the schematic property of the proposed algorithm. We showed the EMVDD of Full Adder by module construction and verified the proposed algorithm by examples. The proposed method has the visible, schematical and regular properties.

It is study about implementation of the home network system that used an ubiquitous sensor network and an embedded system in this paper. PXA270 and CC2420 were used, and the home server of a wireless sensor home network system composed it. A wireless control system is composed of a gas valve, a DC motor, a lamp and a door rock. A wireless detection system is composed of a gas detection sensor, a movement detection sensor, an extension detection sensor The wireless detection system that was an environment sensing system was composed of temperature, humidity, mic, illuminance, a speed-up, infrared rays temperature sensing module, and modular, other RFID established an USB camera, and an ubiquitous home network was composed.

In this paper, Squential circuit was implemented by decision diagram that can analyze and test large amount of functions easily. First of all, Memery device of multiple valued squential circuit was used D F/F, implemented with CMOS current mode. The opreation property of this circuit involved by PSPICE simulation. The result of Decision Diagram sequential circuit is simple and regular for selecting wire routing and posesses the property of analyze, testing. so it suitable for VLSI implementation.

This paper presents a method of constructing the sequential logic machines over finite fields(or galois fields). The proposed the sequential logic machines is constructed by as following. First of all, we obtain the linear characteristics between present state and next state based on mathematical properties of finite fields and sequential logic machines. Next, we realize the sequential logic machines over finite field GF(P) using above linear characteristics and characteristic polynomial that expressed using by matrix.

This paper present a method of GRM constant generation using cell [fi] which is generated over karnaugh map. The proposed method is as following. First od all, we select the arbitrary cell over karnaugh map. Next we arithmetic operate the selected cell with single variable transformation matrix, and mapping into karnaugh map its result. Although we discuss the new GRM generation method applied to polarity circulation.
