FIG. 1 shows an electronic program guide unique to viewer A grouped from an electronic program guide based on electronic program guide data; the program type is set in an (a) column and the display mode of each program is set in a (b) column. In FIG. 1, a news program is displayed in text and a music program is displayed in an icon of musical notes on a music sheet. A sports program is displayed in an icon of a bat and a ball. Since the music program and the sports program are thus displayed in such icon images of reminding the viewer of the program contents, the viewer A can quickly determine the program contents visually.

A microcomputer that can process plural tasks time-divisionally and in parallel, wherein one of a plural programs described by one of the tasks is described as a looped specific task in which the increment of program addresses is fixed, a program counter is usable as a timer counter, a peripheral function instruction is described in the specific task, the peripheral function instruction is set so as to indicate one or more general-purpose registers as an operand. The CPU executes the peripheral function instruction as one instruction and achieves information needed to execute the instruction by a general-purpose register and stores the execution result into the general-purpose registers. An instruction code encoding system includes an operation code and plural operands for indicating operation targets of an instruction in an instruction code and executing an instruction indicated by the operation code on the operation targets. When the operation targets indicated by the plural operands are set to a combination in which an execution result does not vary, the processing corresponding to an instruction different is executed.

A signal processing apparatus for processing a periodic signal outputted from a signal source has a central processing unit and a task switch timer. The central processing unit performs multiple tasks including a signal processing task in parallel. In the signal processing task, the central processing unit starts to process the periodic signal after performing a synchronization processing to synchronize with the periodic signal, setting the task switch timer to a predetermined time upon completion of the synchronization processing, and enabling an interrupt to the central processing unit upon completion of the synchronization processing. The task switch timer disables the interrupt to the central processing unit immediately before expiring. The task switch timer outputs a task switch signal to the central processing unit when expiring, so that the central processing unit switches to the signal processing task.

The invention is directed to the provision of a digital broadcast receiving apparatus that presents the details of a plurality of content for viewing before a user performs a content switching (determining) operation, and thereby enables the user to precheck the details of the plurality of contents by a simple operation and start viewing the desired content quickly. The receiving apparatus includes a display for displaying content by receiving data broadcast, list displaying means for displaying content items in the form of a list, a preview displaying section for displaying the content simultaneously with preview content, a preview switching section for switching the display of the preview content to destination content associated with an item selected by a pointer as the pointer is moved over the content items, and a display control section for displaying a preview of destination content associated with an item located adjacent to the item selected by the pointer.

An image forming apparatus includes a cartridge loading portion removably loaded with a first cartridge containing therein a consumable but carrying no memory storing information on the consumable, or with a second cartridge containing therein the consumable and carrying a memory storing information on the consumable; a controller; and a first memory storing the information on the consumable contained in the first cartridge, and is characterized in that the controller includes: a first consumption calculating/storing portion operating when the first cartridge is loaded in the cartridge loading portion, calculating a consumption of the consumable in the first cartridge and storing the calculation result in the first memory; and a second consumption calculating/storing portion for calculating a consumable consumption of the second cartridge and for storing the calculation result in the memory installed in the second cartridge.
摘要:
A computer program compiler generates object code to be executed by a RISC type of CPU, whereby in effect each bit operational expression appearing in the source code, such as an AND operation on two bit variables, is converted to an operation whereby the respective values of the bit variables which are operands of that expression are judged, and a specific binary value is assigned as the result of the bit operational expression based upon the judgement results, to thereby substantially reduce the number of RISC object code instructions corresponding to such an operation.

The disclosure relates to program information display apparatus including a program data receiving unit for receiving program data of digital broadcasting, and a program in-depth information creating unit for extracting in-depth information of a predetermined program from the program data received by the program data receiving unit, and creating program in-depth information thereof. The program information display apparatus is equipped with a program selection input unit for allowing a user to select and display in-depth information of one program when in-depth information of another program is being displayed, and a program in-depth information display changing unit for displaying program in-depth information of a program selected through the program selection input unit when the program is selected.
摘要:
A microcomputer which is to be utilized in a condition of being built into an apparatus such as a vehicle ECU, includes a ROM having stored therein a program which is prepared by a user and a boot ROM which stores an initialization program for performing at least essential initialization processing which is required for all application programs that will be executed by the microcomputer. The need for the user to generate program contents relating to such initialization processing is thereby eliminated, while increased reliability of operation of the microcomputer is achieved. In addition, it is possible for user-specified initialization data to be read out from a user program and utilized in a part of the initialization processing of the initialization program.

A microcomputer includes a CPU capable of performing a plurality of tasks in a parallel time-sharing operation. The tasks include at least one special task having a fixed loop program with a constant increase of an instruction address. When the CPU performs a conditional judgement instruction in the special task, the CPU prohibits reflecting an execution result of the conditional judgement instruction to both of the CPU and a periphery circuit in a case where it is no need to perform an instruction described in the special task after the conditional judgement instruction.

A navigation apparatus including a joystick which is adapted for three motions of leaning in a plurality of predetermined directions, rotating about an axial line and being pressed in a direction along the axial line. As a result of these three motions, an operation of this joystick can be provided with a lot of navigation functions, and, as compared with the prior art, the number of switches of a remote controller and an operation panel section can be decreased.
