Title: Wait timing controller
Inventor: HONDA IKUYA
IPC: G06F12/06
Filed: 1990-11-21
Abstract: PURPOSE:To improve versatility by exchanging a wait search circuit for the increase of a peripheral equipment and altering a wait cycle table for changing the length of a wait. CONSTITUTION:When a chip selection signal is inputted, the output of DFF 202 becomes valid at a subsequent clock. At that time, an enable signal 206 becomes valid and it starts counting. Since the two inputs of AND 205 become valid at that time, a load signal 207 becomes valid and the output of DFF 203 becomes valid after one clock cycle. Thus, the load signal 207 becomes invalid. When inputs D, C, B and A are data of '1', '10' and '0', for example, they are equivalent to hexadecimal (c). Thus, counting is started from (c), counting is continued to after three clock cycles (f) and a carry signal is outputted. When the value of input data is changed, time till the carry signal is outputted can be changed. Thus, versatility increases since the type of CPU is not selected.
