In wired data transfer network, Transmission Control Protocol (TCP) is widely used to ensure the reliability of transmission. But the protocol requires much CPU resource and has a low transmission efficiency [1]. TCP uses retransmission when time out and data acknowledge mechanism to achieve the ability of reliable transmission [2]. Data receiver must acknowledge data frames with acknowledgement (ACK)...
Traditional satellite navigation receivers usually depend on FPGA chips or ASIC chips, which lack flexibility and multiple constellation support. The paper presents a single DSP multi-constellation satellite navigation receiver hardware design method, and discusses signal sample, buffer and output technology. Furthermore, multi-constellation task scheduler is also discussed. Based on TMS320C6416,...
The paper presents an implementing framework of transaction-based HW/SW(hardware/software) co-simulation. The framework partitions a process of transaction-based co-simulation into 4 function lays, and can be used by a co-simulation system. The hw/sw cosimulation of a packet switch module is implemented on the "CD6501 SoC SW/HW co-verification system" of University of Electronic Science...
