Abstract

PURPOSE:To deal with a change of a stored bit pattern without changing hardware even in case when specifications of an instruction are changed, by storing in advance a bit pattern for an interlock control in a control memory. CONSTITUTION:A control data is read out from a control memory 11 by access information, etc. of the control memory 11, obtained by decoding an OP part of an instruction code inputted to a control memory selecting part 10, and it is set to a tag register 12. In the information read out to this register 12, an information bit for an interlock control is contained, it is decoded by a decoder 18, and one of FF19-FF23 is set in accordance with contents of the control memory 11. On the other hand, in case when there is no bit pattern by which all FFs of FF19-FF23 are set, the instruction is shifted to an R state from a D state. Accordingly, in case when the FF19 has been set, while an instruction A is present in A and B1 state, an instruction B is locked in D state.
