Abstract

PURPOSE:To make it possible to transfer signals via many two-way buses with a less number of signal lines while converting two-way buses into one-way buses, by employing the constitution of an inverter, D type FF, buffer, and three-input N AND gate. CONSTITUTION:Converting circuit A inserted between two-way buses 1 and 2 at both-end parts of a couple of one-way buses 31 and 32 consists of inverter 4, D type FF5, buffer 6, and three-input NAND circuit 7. On buses 1 and 2, and 31 and 32, (a)-(d) are all at ''H'' and the D input and Q output of FF5 are both at ''H''. When signals at points (a) and (b) change, whether the change has been caused by buses 1 and 2 or buses 31 and 32 at the reception side is discriminated 5 to determine whether this signal change is to be transmitted to buses 31 and 32 at the reception side or not. Namely, when a request to hold point (a) at ''L'' is made, point (c) is held at ''L'' and point (b) is then held at ''L'', but point (d) stays at ''H''. Consequently, when the request to hold point (a) at ''H'' is made again, points (a), (b) and (c) are returned to ''H''.
