Title: Clock fault detection circuit
Inventor: OKASHITA KAZUHIRO
IPC: H03K5/19
Filed: 1990-03-13
Abstract: PURPOSE:To detect a clock fault even when a clock frequency is fluctuated increasingly or decreasingly by using two oscillators and counters with a different frequency to detect the fault in a short time such as clock momentary interruption. CONSTITUTION:The relation such as fL<fIN<fH is satisfied among a clock frequency fIN being a fault detection object, a frequency fL of an oscillator OSC 1 and a frequency fH of an oscillator OSC 2. When the clock frequency fIN being a fault detection object is abnormal and fluctuated in a lower frequency and the relation of fIN<fL<fH is satisfied, since the operation speed of a counter CNT0 is reduced, the case of generation of two carrying signals (CO) of a counter CNT1 is present without fail for one period of a carry signal (CO) of the counter CNT0. Thus, the time when the counted value of a counter CNT 3 is 2 is present thereon and a signal appears at the output of a gate GT. Thus, the frequency abnormality is detected.

Title: Peripheral storage controller
Inventor: MATSUMOTO WATARU
IPC: G06F12/10
Filed: 1987-03-18
Abstract: PURPOSE:To improve the data transfer action and the speed of a data processing time of a host computer by accumulating data on a peripheral storage device, which is frequently used in the host computer, in the high speed storage device of a random access system and setting the high speed storage device as an ideal peripheral storage device so as to make the high speed storage device execute a data transfer work with the host computer. CONSTITUTION:When the host computer 1 needs a memory disk 12, the data of a hard disk 10 is transferred to the memory disk 12 by setting a data transfer command in a central processing unit 9 and the memory disk 12 is made to execute the high speed data transfer work in a random access method as an ideal hard disk for the host computer 1. When the host computer 1 does not need the memory disk 12, the data of the memory disk 12 is transferred to the hard disk 10 by dotting an opposite command, and the hard disk 10 restores the action as a usual hard disk. Thus, the data which is frequently used by the host computer, out of the data stored in the peripheral storage device can be accessed at high speed.

Title: Register allocation system
Inventor: TAKECHI YASUHIDE
IPC: G06F9/45
Filed: 1987-03-17
Abstract: PURPOSE:To effectively execute the optimization of an object code by selecting a register whose allocation priority is high and its instruction address in a register management table is the smallest. CONSTITUTION:A register selecting means 3 refers to the register management table 6, and saves the priority of the allocation of a first register and its instruction address in a memory, and later, compares the save content and the content in a second and later on registers. In case a register having a priority of allocation higher than the save one appears, or in case a register whose priority is equal but which has an instruction address in smaller value appears, the appearing register is taken as a save register. This processing is executed for all the registers that are usable for an object code generated by a compiler; a register which is saved lastly comes to be a register employed for an instruction generated in an instruction generation processing 4. As a result, a time interval until the following use for other purpose is uniformized for all the registers, and the rate of achieving the optimization of object codes can be upgraded.
