    摘要: To reduce the hardware of the graphics computer in size and reduce the cost of the hardware, the frame buffer and the main memory are united into one unit to process graphics data in the CPU. The frame buffer is arranged in the main memory, and the graphics computer includes a DMAC used to read pixel data from the frame buffer for display, a display used to receive the pixel data and display it on a display device, such as an LCD, etc., and memories used to store the procedure used by the CPU to draw the pixel data in the said frame buffer. Especially, the said memories are formed so that a single function procedure and a multifunction procedure can be selected to suit the drawing object. In addition, the single function procedure includes a line drawing procedure that uses data tables and a multivalue expansion procedure that uses a pattern table and a mask table. Since the frame buffer and the main memory are united into one unit, the CPU can be used to process graphics data. Thus, the graphics computer hardware is reduced in size and the cost of the hardware is reduced.

    摘要: A counter timer device includes a plurality of registers each capable of performing any of the function of a counter/timer register, the function of a capture register and the function of a compare register, in accordance with a command from a central processing unit, and a plurality of task registers corresponding to tasks which are to be carried out by using the above registers. Each of the task registers stores a task instruction for specifying a counter/timer register and a capture/compare register which are used in a task, and for specifying the operation mode of each of the specified registers. The task registers are scanned to successively read out the task instructions, and each of the read-out task instructions controls the operation of each of registers used in a corresponding task. Thus, tasks corresponding to the task instructions are all carried out at once.

    摘要: A vehicle control system provided with a plurality of sensors for detecting the condition of the vehicle, a vehicle control unit including a multiplexer, a programmable input signal matching module and a processor, and actuators for operating each part of the vehicle. The multiplexer and matching module are selected and switched in accordance with a sensor signal to be inputted. A plurality of sensor signals can be inputted through the switched multiplexer and matching module to the processor. Furthermore, the processor determines controls of vehicle operation on the basis of the inputted sensor signals and controls actuators in accordance with the determined controls.
