In this paper, we have presented a design of hybrid arithmetic logic unit (ALU) in Double precision format (DPF) according to the IEEE-754 standard. In this we have designed an ALU which consists of the two different architectures. First architecture is semi-floating point unit (Semi-FPU) and the second architecture is floating point unit (FPU). Semi-FPU takes a 32-bit integer input and produces an...
Avionics systems, along with their internal hardware and software components interfaces, must be well defined and specified (e.g., unambiguous, complete, verifiable, consistent, and traceable specification). Such a specification is usually written in the form of an Interface Control Document (ICD), and represents the cornerstone of the avionics system integration activities. However, there is no commonly...
ACM and the IEEE Computer Society have released their computer engineering curriculum guidelines in December of 2016. The curricular report, tagged CE2016, reflects current computer engineering education and practice that would be relevant for the coming decade. The report provides some examples on ways to map knowledge units to courses and it addresses expected requirements in science and mathematics...
According to the characteristics of aerospace computer products, this paper proposes aerospace computer productization work architecture and its detail implementations, which includes three key factors: product system plan, technical factors and management factors. By adopting this architecture, we can effectively improve the performance of aerospace computer productization.
Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. Memory can be found in all aspects of the semiconductor world. This tutorial will review the volatile memories found in today’s computers and networking equipment, including DRAM, SRAM and TCAM. For each of these memories we will cover bit cell structure, array...
Future avionics is no longer mere close electronic systems with the requirement changed, while it is pervasively controlled by dozens of frequent information exchange, open architecture and highly automatic systems. And this transformation has driven major advancements of security in avionics which contains computing security and communication security. Our team is focused on the security of next...
To satisfy more and more complicated requirements on information recording, processing, exchange etc. in newly developed intelligent satellites, a distributed storage system is designed based on SpaceWire network in satellite platform. In this distributed storage system, a SpaceWire router unit serving as the core device of star network connects several nodes, including onboard computers, namely,...
ACM and the IEEE Computer Society plan to re-lease their computer engineering curriculum guidelines at the end of this calendar year. The curricular report, tagged CE2016, reflects the state-of-the-art in computer engineering education and practice that would be relevant for the coming decade. This panel presentation provides an overview of the report and it also provides unique perspectives from...
In recent years, computer system capability training becomes an important research issue for teaching reforms of computer major. This paper propose a new system ability training scheme via analyzing the existing reform methods. By establishing core courses and optimizing experimental teaching system, our reform completes the teaching target that let undergraduate students to develop a CPU, an operating...
System integrators for commercial aircraft reason about the subsystems they must integrate using Interface Control Documents (ICDs). Although ICD format standards exist in this specific domain, avionics suppliers express their ICDs in different ways, making the integrator's work challenging. As software engineering researchers, we are trying to define a common vocabulary for ICDs in the context of...
The audience will discuss the current state of the effort to update the 2004 document titled "Curriculum Guidelines for Undergraduate Degree Programs in Computer Engineering," also known as CE2004. The presenters represent the ACM and the IEEE Computer Society (IEEE-CS), which are leading the effort. They will engage participants on ways of improving the body of knowledge so that the document...
Innovative approaches for securing the computing systems have intense inference for our understanding of technological, societal, economical, and political phenomena in making guiding principles, policies, rules and security implementations. The model presented here is based on cooperative and collaborative multilateral relationship among the shared business community partners. The sole responsibility...
Since the beginning of study of the Secure Hash function (SHA), it has been thoroughly studied by designers with the goal of reducing the area, frequency, throughput and power consumption of the hardware implementation of this cryptosystem. The Secure Hash function algorithm has become the default choice for security services in numerous applications. Following the attacks considerable standard SHA-2,...
In the current era of big-data computing, most non-engineer domain experts lack the skills needed to design FPGA-based hardware accelerators to address big-data problems. This work presents bFlow, a development environment that facilitates the assembly of such accelerators, specifically those targeting FPGA-based hybrid computing platforms, such as the Convey HC series. This framework attempts to...
The combination of the Near Field Communication (NFC) technology and the Mobile Communication technology produced many convenient application modes, and take a new blueprint to the development of the smart city. It is the key problem to the development of smart city that establishing an efficient system to support the application of NFC. This paper puts forward a cloud architecture that based on NFC...
Multiplication, as one of the four basic operations embedded in arithmetic processors, is nowadays experiencing being spotlighted by the hardware designers involved in the revived decimal arithmetic. The decimal hardware units usually employ the sequential implementation for this operation, due to the high area cost of the parallel decimal multipliers. However, the main drawback of this iterative...
This paper presents the use of Near Field Communication and mobile technologies for the development of ubiquitous games. We describe all the components necessary for the building of ubiquitous games: the MIDlet or program running on the mobile phone with NFC features, the services available in the back-end system in charge of the game control and the tool devoted to real-time surveillance and visualization...
This paper describes our approach to develop Computer Adaptive Testing functionality for different Learning Management Systems following educational standards and specifications (defined by the IMSConsortium). This functionality can be integrated into standard-based personalized learning routes and is being developed as a Service Oriented Architecture(SOA) to support its generality and applicability.
The PJM Interconnection, one of the North American Regional Transmission Organizations (RTO), is responsible for the security coordination and reliable operation of a major part of the Eastern Interconnect, with a service area covering thirteen States and Washington DC, and over 165,000 MW of installed generating capacity. It is also responsible for the administration and operation of the associated...
