Processor to process tagged and untagged data. |
摘要 |
<p>A data processor (100) for execution of tagged data and tagless data has a decoder (130) for discriminating whether the data is tagged or tagless one and in case of a tagged data, separates a tag part and uses the remaining part for address computation. The data processor also comprises a unit for evaluating the tag part and a micro program controller (290) for multi-branching in accordance with the evaluation result of the tag part. The tag evaluating unit includes an extender eliminating part (250) for extracting the tag part from data on a data bus (340), a plurality of tag part storing registers (260, 270) for storing the tag part from the eliminating part under the control of the micro program controller, and a tag multi-way jump encoder (292) for generating a tag multi-way jump address to feed it to the controller on the basis of the outputs of the registers and a signal from the micro program controller, thereby enabling tag multi-way jump. <IMAGE></p> |
