摘要:
A computer implemented logic simulation method, for inspecting logical operations of large scale logic circuits, computes a variation of an output of at least one latch in a clock synchronized logic circuit. The clock-synchronized logic circuit contains a combination logic circuit and a plurality of logic gates. Each of the logic gates have at least one input signal and several other inputs connected to clocking signal sources of different phases. The latch is activated by the rise or fall of the clock signals for holding the output from the combination logic circuit. The method thus implements sampling instants of the output for ascertaining the logical operations of the large scale circuits.

In response to the execution of a single loading instruction, the front half and the rear half of a designated vector may be stored in respective vector registers in a single processor operation. For this purpose, a data distribution circuit is interposed between a group of vector registers and a vector data storage for feeding the vector data read out from the storage to a first vector processor designated by an instruction without shifting and for shifting the respective components of the read-out vector data and feeding the shifted components to a second vector register designated by the instruction.

A vector processor has a discriminator for determining in one machine cycle of an operation unit whether a bit pattern of elements of vector data meets a predetermined condition or not. An output of a register having a predetermined value loaded only into bits to be extracted from the vector data and each of the elements of the vector data are ANDed or ORed so that the bit pattern is determined. The operation and determination are sequentially carried out in one machine cycle.

A method of logic simulation for simulating operation of a logic circuit by using basic signal values corresponding to states of output signals of elements of the logic circuit to be simulated and expanded signal values including the basic signal values. The logic circuit to be simulated is divided into a portion to be simulated by using the basic signal values and the expanded signal values and a portion to be simulated by using the basic signal values without using the expanded signal values. The elements for which definition of calculation method for output signal values for the input signal values including the expanded signal values is not easy are included in the latter portion, and other elements are included in the former portion. A virtual signal conversion element for converting the expanded signal into the basic signal is provided at a position where a signal is sent from the former portion to the latter portion so that the expanded signal value outputted from the element of the former portion is converted into the basic signal value before it is sent to the element of the latter portion.

In a vector processor for performing an operation on first and second vectors for each vector element, an operation code is set for each vector element of at least one of the first and second vectors to designate the type of an operation to be executed on the vector element, and the operation is carried out on the first and second vectors for each vector element based on the operation code.

The present invention provides an image processing apparatus which can perform image processing suitable for each image in a job as well as provides an image processing program storage medium. The image processing apparatus has an information storage section which stores processing information used for predetermined image processing in memory by associating it with front and back sides of paper each, a color conversion section which performs a color conversion process on an image based on the processing information associated by the information storage section with the front or back side on whichever the image is to be recorded, and a RIP section which converts the image data after color conversion into raster data while performing a correction process on the image data to correct image distortion.

A printing apparatus, a control method therefor, and a medium on which the control method is stored, enable selection of a resume operation to be performed when the printing apparatus resumes operation following an off-line state. The resume operation to be performed after an off-line state is determined by a command received from a host device according to the cause for the off-line state. The resume operation thus determined is performed when the printing apparatus goes on-line again following the off-line state. A marker indicating a particular location in a continuous data stream can be set. If the marker is placed at the beginning of a particular data stream, printing can be resumed from the beginning of the data stream after recovery from an off-line state. By also storing various printer definitions (settings) when a marker is set, the printing apparatus can also be restored to the printer definitions in use when the printer went off-line. By setting a plurality of markers, printing can also be resumed from a selected marker.
