The existing LDPC encoder exists the problem of high computing complexity and much resources consumption, therefore, a strategy of LDPC fast encoding based on dynamic memory structure of linked list queue is proposed in this paper. Specifically, this strategy simplifies the design of encoder by making full use of the characteristics of the parity check matrix structure and sparsity. On the basis of...
This paper presents a memory hierarchy with the support of network-on-chip (NoC) for MPSoC systems. The memory hierarchy consists of a shared global memory and private local memories. Each core in the system is equipped with two local memories, one for instructions and one for data. Those local memories are connected through a NoC for efficient data communication. We tested two different settings...
Physically unclonable functions (PUFs) have been a hot research topic in hardware-oriented security for many years. Given a challenge as an input to the PUF, it generates a corresponding response, which can be treated as a unique fingerprint or signature for authentication purpose. In this paper, a delay-based PUF design involving multiplexers on FPGA is presented. Due to the intrinsic difference...
Cloud computing, a delivery of computing as a service mainly implying how to use utilities in our context, can be provided either at infrastructure, platform or software levels. The Desktop-as-a-Service (DaaS) paradigm, derives from the software level Software-as-a-Service (SaaS) paradigm, is drawing increasing interest because of its transformation from desktops into a cost-efficient, scalable and...
