    • An information processing apparatus that has multiple functional parts and power management domains that serve as control units when supplying power to the functional parts, and that autonomously controls supply of power to the power management domains, the apparatus including a power supply control part that supplies power to only a power management domain that includes the functional part associated with execution of an input instruction, and that stops the power supply to the power management domain in response to termination of execution of an instruction by the functional part; and an execution result storage part that stores a result generated by execution of an instruction by the power management domain to which power is supplied by the power supply control part, independently of the power supply control part supplying power and stopping the supply of power; wherein, after supply of power to a power management domain that terminates execution of an instruction is stopped by the power supply control part, another power management domain to which power is supplied reads out a result that is stored in the execution result storage part.

    • There is disclosed a character rendering device capable of rendering characters at a higher speed. The character rendering device includes an internal storage unit including plural storage areas; a first bus connected through an external bus to an external storage unit storing character shape data sets, each expressing a shape of a character; a second bus connected to the internal storage unit; a controller that specifies one of the plural storage areas; a first rendering unit connected to the first and second buses, that renders a character shape of a character based on one of the character shape data sets supplied through the external bus and the first bus, and writes through the second bus the rendered character shape into one of the storage areas specified by the controller; a second rendering unit connected to the second bus, reads through the second bus, each time when writing of a character shape into one of the plural storage areas is completed by the first rendering unit, the character shape from one of the plural storage areas, and renders a character based on the read character shape; and a transfer unit that transfers the character rendered by the second rendering unit.
    • 公开了一种能够以更高速度呈现字符的字符再生装置。 字符渲染装置包括:包括多个存储区域的内部存储单元; 通过外部总线连接到存储字符形状数据集的外部存储单元的第一总线,每个表示字符的形状; 连接到内部存储单元的第二总线; 指定多个存储区域中的一个的控制器; 连接到第一和第二总线的第一渲染单元,其基于通过外部总线和第一总线提供的字符形状数据集之一呈现字符的字符形状,并且通过第二总线将所渲染的字符形状写入 控制器指定的存储区域之一; 连接到第二总线的第二渲染单元,每当通过第一渲染单元完成将字符形状写入多个存储区域之一时,通过第二总线读取来自多个存储区域中的一个的字符形状, 并基于读取的字符形状呈现字符; 以及传送单元,其传送由第二渲染单元呈现的角色。
