Filed: 1981-07-06
Abstract: PURPOSE:To manage with only one control signal input terminal for switching types of noise reduction, by putting a circuit in three kinds of operation in accordance with a ternary input signal. CONSTITUTION:The reference voltage VREF developed at a connection point J2 is equal to the potential obtained by dividing a power voltage through resistances R1 and R2.

The base potential of a TRQ3 is a voltage VREF-3VBE the 3VREF of three diodes lower than the VREF. A switching control signal VS is supplied to the base terminal of a TRQ2. When the VS is nearly equal to the power voltage, the base potential of the TRQ2 is VREF+2VBE and higher than the base potential of the TRQ1, so the TRQ1 turns off and the TRQ2 turns on to generate a control signal (c), placing a noise reduction circuit in mode (c). When the VS is as high as the VREF, the TRQ1 turns on and the TRQ2 turns off to generate a control signal (b).

Title: Information processor
Inventor: YAMAHATA HITOSHI
IPC: G06F9/46
Filed: 1987-04-28
Abstract: PURPOSE:To improve the processing speed of an information processor without any unnecessary increase in hardware by comparing register number information with working register information and generating information for privilege exception detection when execution level information indicates an instruction of non-privileged level. CONSTITUTION:For example, a source-side operand is a register operand, a register R1 is specified, and a value (m) is held as a register number 105. A source-side comparator 106 compares the both and outputs 1 when m<=1. An SROP signal 101 is 1 and the output of a source-side mask gate 108A is 1 so that the source-side operand is the register operand. The output of an OR gate 111 is therefore 1. When a privileged level signal 112 is 0, namely, when a program is being executed at non-privileged level, an AND gate 114 outputs 1 and the privilege exception signal 115 becomes 1 for an instruction execution part 203, so that a privilege exception is detected. Consequently, the processing speed is improved without any increase in hardware.
