Title: Multifrequency signal receiver
Inventor: FUJII KENSAKU
IPC: H04Q1/457
Filed: 1981-03-03
Abstract: PURPOSE:To eliminate the need for an expensive window function generating circuit by supplying an input signal to a linear cyclic digital filter, which sends out an output signal based upon a past input signal, at every point of sampling. CONSTITUTION:Adders 44-46, multipliers 36-39, and one-sampling-period delay registers 51 and 52 constitute a linear cyclic digital filter to which a window function of a past sampling period is considered to be applied at every sampling point. When an input signal is inputted to a terminal 1, the linear cyclic digital filter performs discrete Fourier transformation and sends a read part and an imaginary part output to terminals 20r and 20i. Both the outputs are squared by multipliers 33 and 34 respectively and then added by an adder 43, whose output proportional to the amplitude of a component of a necessary detection angular frequency is sent out to a terminal 2. According to the addition output, the presence of the input signal having the necessary detection angular frequency is discriminated.

Title: Method and equipment for processing image display data
Inventor: RESURII DEIIN KOON
IPC: G06T15/40
Filed: 1990-02-14
Abstract: PURPOSE: To improve the throughput of a graphic pipeline by shifting a pixel mask by a prescribed number N of bits and selecting N values from new Z values are comparing them with N corresponding Z valves retrieved from a Z buffer and storing smaller values. CONSTITUTION: A Z buffer check instruction simultaneously executes unsigned integer (order number) comparison between a newly calculated distance (Z) value and contents of the Z buffer plural times. The distance of a point to be extracted is compared with a corresponding value in the Z buffer, and then, a proper bit of the pixel mask is set for the purpose of designating a pixel where the point to be extracted is closer (smaller) than the Z buffer value. Preceding calculated bits of the pixel mask are so shifted that continuous Z buffer check instructions accumulate the results in a pixel mask register. In the case of the 16-bit Z value, comparison and pixel mask update are simultaneously executed four times in one instruction cycle. Thus, the throughput of the graphic pipeline is improved.
