Abstract: When an interruption instruction occurs in an information processing apparatus including a CPU and a coprocessor, execution of a single dedicated instruction “GETACX Dm,Dn” performs saving of necessary data from all registers. “Dm” is a value output from a general register group 104 to a first data input bus 120. Each of calculation units implemented in a coprocessor 110 recognizes a value stored therein. If a value “Dm” specifies one of the calculation units, the specified calculation unit outputs, to a selector 116, data stored in a register included in the specified calculation unit. An implemented calculation unit information output circuit 117 stores therein the count of the calculation units implemented in the coprocessor 110. If a value of the first data input bus 120 is greater than the count of the calculation units, the implemented calculation unit information output circuit 117 outputs a value “1” to a flag register 102.

Abstract: To provide a signal processor for performing processing in fewer cycles by selecting one of the two different operations in accordance with a flag signal and performing the selected operation without the use of a conditional branch instruction, the signal processor is provided with an instruction decoder, a control selecting circuit, a selecting circuit and an arithmetic unit. The instruction decoder decodes an instruction to output two control signals. The control selecting circuit is connected to the instruction decoder and selects one of the control signals in accordance with a flag signal stored in a flag holding circuit to output the selected signal. The selecting circuit selects one of a plurality of input data in accordance with the control signal outputted by the control selecting circuit and outputs the selected data. The arithmetic unit performs an operation on the data outputted by the selecting circuit.

Abstract: According to the signal processing method of the invention, control data is previously generated by using the name of a control signal included in an object signal, and then, the object signal including the control signal is input. The name of the control signal in the control data is substituted with the content of the control signal included in the object signal, and then the object signal is processed by a signal processing unit by using the control data including the content of the control signal. Therefore, the signal processing unit can change the processing to be performed on the object signal in accordance with the content of the control signal included in the object signal.

Abstract: A plurality of processing elements are connected in cascade so as to constitute a single signal processing apparatus. The signal processing apparatus has a first path for transferring an input data signal and a second path for transferring a processing result of the input data signal.

Abstract: A plurality of signal processing elements are cascade-connected to form a signal processor having three signal paths. The signal processor is a small-sized device which can be shared by sum-of-products calculation and division. In each signal processing element, first and second shifters and an adder-subtracter are used for performing shift addition for multiplication of a variable by a constant which is a basis of the sum-of-products calculation. The adder-subtracter and a third shifter for shifting a result obtained by the adder-subtracter are used for performing subtraction and shifting for obtaining a partial quotient and a partial remainder of division. The partial quotient thus obtained is transferred to the signal processing element in the next stage through a flag holding circuit.

Abstract: A duty ratio-guaranteed reference clock signal and a duty ratio-unguaranteed drive clock signal serve as input to a clock signal waveform-correcting system in accordance with this invention. The system thereafter puts out a post-correction drive clock signal that is duty ratio-guaranteed. The system has a phase comparator and a switch circuit. The phase comparator puts out a HIGH signal as long as the reference clock signal and the drive clock signal disagree in logical level. The switch circuit transmits an inverted signal as a result of inverting the drive clock signal, to an output signal of a first buffer to which the drive clock signal is applied. A second buffer takes in the output signal and puts out a post-correction drive clock signal.

This coprocessor has a parallel sum-of-products arithmetic operation section, a comparator, an I/O register section, and a sum-of-products factor register section. A frame memory, provided on the input side, stores MUSE or NTSC signals digitized per pixel. The DMA is in control of the transfer of data between the input-side frame memory and the data memory as well as the transfer of data between a frame memory provided on the output side and the data memory. Pixel data stored in the data memory is processed according to broadcasting systems by the switching of sum-of-products factors on the basis of software.
