    • Provided is an on-vehicle network which can improve the network use efficiency and reduce the controller processor overhead even when the same communication cycle as the frame cannot be set in the filtering condition of a communication control device. A reference signal transmission controller is arranged in a network so as to generate and transmit a reference signal in accordance with the communication cycle. A reference signal reception controller receives the reference signal and compares the reference signals to a predetermined filtering condition table. If the signal is matched with the table, the controller executes a data reception process and a data transmission process.

    • When executing successive processing of conventional software, a parallel processing apparatus turns a processing state discrimination flag off, increases a program count by 1 at a time, reads out one instruction, and processes that instruction in an arithmetic unit. When executing parallel processing for new software, the parallel processing apparatus turns the processing state discrimination on, increases the program count by m at a time, reads out m instructions, and exercises parallel processing over m instructions in m arithmetic units. In order to select either of the above described two kinds of processing, a discrimination changeover instruction having function of changing over the processing state discrimination flag is added. Instructions are processed in arithmetic unit(s) in accordance with the processing state discrimination flag. In this way, successive processing and parallel processing are provided with compatibility and are selectively executed. Further, the parallel processing apparatus making great account of compatibility of a great part of software reads out m instructions without using the processing state flag, decodes the m instructions, checks whether a branch instruction exists in the k-th instruction, then executes the first to the (k+1)-th instructions in k+1 arithmetic units, and prevent execution of the (k+ 2)-th to m-th instructions. By executing the k-th branch instruction, the parallel processing apparatus calculates an address nm+h of its branch destination, performs calculation to check whether the condition is satisfied or not, then prevents execution of instructions of addresses nm to nm+h-1, and executes instructions of addresses nm+h to (n+1)m. In this way, the parallel processing apparatus executes a plurality of instructions and successively executes branch instructions.
    • 当执行常规软件的连续处理时,并行处理装置将处理状态判别标志关闭,一次将程序数增加1,读出一个指令,并在运算单元中处理该指令。 当执行新软件的并行处理时,并行处理装置将处理状态判别转为一次,一次增加程序数m,读出m个指令,并对m个运算单元中的m个指令进行并行处理。 为了选择上述两种处理之一,添加具有改变处理状态判别标志的功能的识别切换指令。 指令根据处理状态判别标志在算术单元中进行处理。 以这种方式,连续处理和并行处理具有兼容性并且被选择性地执行。 此外,大量软件的兼容性的并行处理装置在不使用处理状态标志的情况下读出m个指令,对m个指令进行解码,检查第k个指令中是否存在转移指令,然后执行第一 到第k + 1个算术单元中的第(k + 1)个指令,并且防止执行第(k + 2)至第m指令。 通过执行第k个分支指令,并行处理装置计算其分支目的地的地址nm + h,执行计算以检查条件是否满足,然后防止执行地址nm到nm + h-1的指令 并且执行地址nm + h至(n + 1)m的指令。 以这种方式,并行处理装置执行多个指令,并连续执行分支指令。
