摘要： A channel communicator (CC) has a storage array for holding an entry for each channel and for holding a busy vector and an interrupt vector that each have a bit for each channel. The channel communicator (CC) is connected between the input bus and the output bus that connect the channels and an I/O processor (IOP) to processor main store. A message to the channel communicator (CC) includes the identification (ID) of the channel that the message is to or from and the channel communicator (CC) uses this identification (ID) as an address for accessing a channel entry or a bit in a vector. The message also carries a command that controls the channels communicator (CC) to store a data portion of a message or to fetch a channel entry or a vector from the array and load it onto the output bus addressed to the I/O processor (IOP) or to one of the channels. The command also controls addressing a particular one of the vectors. The channel communicator (CC) also has means responsive to a command to perform a sequence of operations for testing the vectors and for testing fields of an entry in the array and for using the results of the test to control the execution of the command.

摘要： A binary number substitution mechanism includes first and second storage arrays addressed by first and second portions, respectively, of an input binary number, producing a substitute output binary number. The input binary number represents a predetermined number of microinstruction addresses in a read-only store, and the output binary number is representative of microinstruction addresses in a main storage device. Only a limited number of the possible input binary numbers are required to access the first and second storage arrays to read out selectively stored binary numbers to create a limited range of output binary numbers unique to each of the limited number of the input binary numbers.
Further, compression of the range of output of binary numbers as substitution for certain ones of the binary input binary number is achieved by addressing the first and second storage arrays by first and second portions of the input binary number to which a certain number of the input signal line of the first and second portions are common.摘要翻译： 二进制数替换机制包括分别由输入二进制数的第一和第二部分寻址的第一和第二存储阵列，产生替代输出二进制数。 输入二进制数表示只读存储器中的预定数量的微指令地址，并且输出二进制数表示主存储设备中的微指令地址。 仅需要有限数量的可能的输入二进制数来访问第一和第二存储阵列以读出有选择地存储的二进制数，以创建每个有限数量的输入二进制数特有的输出二进制数的有限范围。 此外，通过用输入二进制数的第一和第二部分对第一和第二存储阵列进行寻址来实现二进制数的输出范围作为二进制输入二进制数中的某些的输入的二进制数的压缩， 第一和第二部分的信号线是共同的。
