Title: Microprocessor
Inventor: TAKAGI KATSUAKI
IPC: G06F9/46
Filed: 1986-10-30
Abstract: PURPOSE:To speed up table retrieval and to enable a system programmer to describe a retrieval routine freely by fetching a program from an emulation space for an interruption recognized as an emulation interruption by an interruption deciding means. CONSTITUTION:If an emulation interruption such as a conversion couple absence interruption is caused, an interruption processing routine for the retrieval, etc., of an address conversion table is accessed while an emulation space signal 2 is asserted. The emulation space 6 is separated from a normal space where a normal program is run, so it seems that there is no program in the emulation space 6 because of an operating system which performs control as to the normal space. Consequently, the system programmer can describe the program of the emulation space 6 freely as instruction words defined as the external specification of a microprocessor 1. Further, an emulation program can be handled as if it were realized by hardware such as a microprogram.

Title: Power source voltage detection circuit
Inventor: ONISHI JUN
IPC: G04G99/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce detection voltage which changes by dispersion of production by connecting the resistor of a detection voltage selection means and an N type electric field effect transistor (NMOS) in parallel, short-circuiting NMOS to VSS by a control signal, and nullifying the resistant value of the resistor. SOLUTION: When the control signal 123 'high' is applied to a P-type electric field effect transistor (PMOS) 121 constituting a detection voltage selection means 12, PMOS 121 is turned off. As the result, three detection resistors Rx, Ry, Rz apply the signal of 'low' to NMOS for power source voltage VSS and the on-resistance of NMOS 122 is a limitless resistant value. Since second NMOS 123 applies 'high' of a control signal 2, it is turned on, the connection point of the detection resistors Ry, Rz is a power source level between conduction is performed between a source and a drain, and the detection resistor Rz is nullified. Thereby a plurality of voltages can be detected, and since no circuit corresponding to detection voltage number is required, circuit scale can be reduced.
