Applying the theory of the modelling method, this paper gives the redesign of the frame structure of tributary mapping interface and calculates the jitter with byte stuffing and bit stuffing respectively. 本文运用模型法原理,分别以字节和比特为单位重新设计了支路映射接口帧结构。
According to the bit stuffing mechanism of the CAN bus and the worst-case message response time models, a master-based message scheduling method is presented for periodic messages. The message response time model based on this method is given. 结合CAN总线的位填充机制和最坏情况下的报文延迟时间的数学模型,针对周期性报文,提出基于主节点的报文调度方式,给出了该调度方式下的报文响应时间数学模型。
An interaction between bit stuffing and the use of cyclic redundancy code ( CRC) can depress the reliability of CAN. CAN的位元填充和CRC之间存在相互作用,可能会降低CAN总线的可靠性。
The paper elaborated on the register configuration of the digital control circuit module, and send data to the control logic state machine, the NRZI module, bit stuffing module, parallel to serial module implementation of principles and methods. 论文详细阐述了数字控制电路中的寄存器配置模块、数据发送控制逻辑状态机、反转不归零编码模块、比特填充器模块、并行转串行模块的实现原理和方法。
