摘要： A data processor in which a speed of an address translating operation is raised is disclosed. A translation lookaside buffer is divided into a buffer for data and a buffer for instruction, address translation information for instruction is also stored into a translation lookaside buffer for data, and when a translation miss occurs in a translation lookaside buffer for instruction, new address translation information is fetched from the translation lookaside buffer for data. A high speed of the address translating operation can be realized as compared with that in case of obtaining address translation information from an external address translation table each time a translation miss occurs in the translation lookaside buffer for instruction.

摘要： A data processor is provided with a first register storing a first half word of one instruction; a second register storing a second half word of the instruction; a first decoder decoding the first half word and at the same time detecting whether there exists an addressing extension portion between the first half word and the second half word; a second decoder decoding the second half word; and, a decode result generating circuit, to which a detection signal of the first decoder indicates whether the addressing extension portion exists. A decode result of the first decoder and a decode result of the second decoder are supplied to the decode result generating circuit. An extension portion register is provided to store the addressing extension portion. When the first decoder detects the addressing extension portion, the decode result generating circuit invalidates the decode result of the second decoder. On the other hand, in the case where there exists no addressing extension portion, the decode result generating circuit judges, on the basis of the detection signal, that the decode result of the second decoder is valid.

摘要： When a leakage current of a circuit block under a non-use state is reduced by means of a power switch, frequent ON/OFF operations of the switch within a short time invite an increase of consumed power, on the contrary. Because a pre-heating time is necessary from turn-on of the switch till the circuit block becomes usable, control of the switch during an operation deteriorates a processing time of a semiconductor device. The switch is ON/OFF-controlled with a task duration time of a CPU core for controlling logic circuits and memory cores as a unit. After the switch is turned off, the switch is again turned on before termination of the task in consideration of the pre-heating time.
摘要翻译：相反，当通过电源开关减小不使用状态下的电路块的漏电流时，短时间内开关频繁的接通/断开操作会引起消耗功率的增加。由于开关的接通需要预热时间，直到电路块变得可用，所以在操作期间的开关的控制使半导体器件的处理时间变差。该开关通过CPU核心的任务持续时间进行ON / OFF控制，用于将逻辑电路和存储器核心作为一个单元进行控制。关闭开关后，考虑到预热时间，开关将在任务结束前再次打开。
