Recently, the express service develops rapidly. However, traditional express service suffers from several noteworthy drawbacks, e.g., Low level of informatization, high risk of information leak and low efficiency of freight. In this paper, we propose a new express management system based on encrypted QR code to overcome above problem. Firstly, the system adopts an encrypted QR code to store all information...
In order to derive the optimal on-chip memory architecture for a given application, the embedded system designer must spend considerable time evaluating potential memory designs. However, tight time-to-market constraints enforce short design cycle time. In this paper we present an effective method to fast and accurately estimate the on-chip data memory performance which employs SPM and cache hybrid...
It is a great challenge to design an On-Chip Bus (OCB) system to meet the extremely high bandwidth requirements in HDTV SoC decoder. In this paper, an OCB system with high throughput and flexibility based on the multi-bus architecture is proposed. A static time division multiplexed scheduling arbitration with central arbitration structure is also brought forth thereafter. Finally, a bus switch with...
Data allocation of on-chip scratch-pad memory is a key problem for the performance of embedded system employing SPM as on-chip data memory. Based on the solution to knapsack problem, we propose its knapsack model then employ dynamic planning method to give its optimal algorithm with the complexity of O(nC). Experiment results show that the method proposed in this paper can obtain the optimal result...
To improve the performance of microprocessor, many kinds of novel architecture, such as multi-thread processor, CMP, PIM, and reconfigurable computing processor, have been proposed. These new processors improve performance mainly dependant on making use of all kinds of parallelism of workloads, solving the speed mismatch between processor and external memory, reconfigurable computing, and etc. This...
