CONTROL INTEGRATED CIRCUIT |
摘要 |
<p>A control integrated circuit of the invention is based upon a hierarchical processor structure. A microprogram controller (211) is employed for a high-order processor to give sophisticated functions. A plurality of finite-state transition machines (208, 209) are employed for a low-order processor to increase the speed of operation. The control function for an external input/output device is divided and is executed by a plurality of finite-state transition machines (208,209), the performance thereof being controlled by the microprogram controller (211). According to the present invention, a new control function is processed by adding a finite-state transition machine (210). Namely, the invention provides the general structure of an integrated circuit for controlling various input/output devices.</p> |
