Filed: 1991-10-04
Abstract: PURPOSE:To provide the function of the digital filter even when a fault takes place in one or plural multipliers by providing a changeover means to change the connection of each delay circuit and the connection of each multiplier to the filter. CONSTITUTION:Suppose that a 2nd multiplier 4b is faulty among 1st multiplier 4a-4th multiplier 4d. At first a control signal turns on 1st, 2nd, 5th, 7th switch circuits 12a, 12b, 12e, 12g and turns off 3rd, 4th, 6th switch circuits 12c, 12d, 12f.

Filed: 1990-09-28
Abstract: PURPOSE:To form a narrow isolating region and to miniaturize it to 1mum or less by selectively etching the sidewall of a polysilicon formed by oxidizing an opened polysilicon and an Si substrate formed thereunder. CONSTITUTION:Since an oxide film 7 formed on the sidewall of a polysilicon 6 by a thermal oxidation method is element-isolated, the opening of the polysilicon 6 is performed by considering it. Then, polysilicon 6' is again deposited, etched back from the surface, and so controlled as to form the surface of the polysilicon 6. Thereafter, after the film 7 is anisotropically etched, an Si substrate 1 is etched by anisotropically etching. In this case, the polysilicons 6, 6' are etched, but since the polysilicon is thicker than the etching depth of the Si, its part remains without etching. Dopant is implanted to the etched part in the Si. The polysilicons 6, 6' and an oxide film 2 are removed to isolate elements.

Abstract: PURPOSE:To enable learning processing corresponding to a learner by dividing the result of document processing which is performed by learning processing by a specific number through a display control means and displaying a cursor mark which indicates a display position for each divided display on a display means. CONSTITUTION:The display control means 300 divides the result of document processing performed by learning processing by the specific number and the cursor mark which indicates a display position for each divided display is displayed on the display screen of the display means 100. Then when the learner instructs a slow display speed by an input means 200, many cursor marks are displayed on the display screen of the display means 100, so the progress speed of the learning processing is slowed down. Further, a cursor mark is displayed at the display position of the document processing result, so the learner notices the document processing result. Consequently, learning efficiency is improved.

Title: Floating point arithmetic unit
Inventor: IDE YUKIHIRO
IPC: G06F7/00
Filed: 1990-09-29
Abstract: PURPOSE:To speed up an adding/subtracting processing by executing the rounding processing and normalizing processing of an arithmetic result in parallel and selecting a real answer from the processed results of respective processing means. CONSTITUTION:When an arithmetic result is applied to a priority encoder 7, the number of shift steps necessary for normalization is calculated as a shift stepping signals. A normalizing circuit 8 normalizes the operated result in accordance with the shift stepping signal and outputs a normalized result. When the arithmetic result is applied to a rounding processing circuit 11 in parallel with its input to the encoder 7, the circuit 11 decides whether increment processing is to be executed or not based upon a rounding mode signal and applies a rounding decision signal to an incrementer 10, which executes the rounding processing of a mantissa part shifted by the rounding decision signal and outputs a rounding result. An answer selecting circuit 12 selects a real answer out of the normalized result and the rounded result. Thus, adding/ subtracting processing can quickly be executed.
