PURPOSE:To realize a two-way data link of simple constitution by bearing exactly symmetric input and output register relation between CPUs by adding a couple of input and output registers between signal buses connected to the CPUs. CONSTITUTION:The 1st and 2nd CPUs 1a and 1b are connected to signal buses 16a and 16b, which are connected mutually by couples of word output registers 2a and 3a and word input registers 4b and 5b, and difference couples of word output registers 2b and 3b and word input registers 4a and 5a. Then, the CPUs 1a and 1b constitute the 1st and 2nd processors A and B, and the relation of input and output registers between both the devices A and B is made symmetric; the buses 16a and 16b are connected in both directions by bit output registers 6a-10a and 6b-10b, and bit input registers 11b-15b and 11a-15a, thus realizing a two-way data link of simple constitution between the processors A and B. |
