Embodiment Construction

[0025] An object of the present invention is to provide a reconfigurable processor and semiconductor device that can finely control operations without affecting affect other functions.

[0026] Embodiments of the present invention will now be described with reference to the drawings. First, an overview of the present invention applied to the embodiments will be given, and then the details of the embodiments will be described.

[0027] figure 1 is a schematic diagram of the present invention applied to an embodiment. A reconfigurable processor according to an embodiment of the present invention includes an arithmetic logic unit (ALU) group including a plurality of ALUs arranged, for example, like a matrix, and a sequencer 2 for controlling the operation of the ALU group. For example, two input ports of ALU 1 included in the ALU group are connected to register groups 3 and 5 via selectors 4 and 6, respectively.

[0028] The ALU 1 accepts data output from the previous stage ...

Abstract

A reconfigurable processor that finely controls operation without exerting an influence upon other functions. Register groups are connected to input ports of ALUs via selectors. Data inputted to an ALU is held in a register selected by a selector under the control of a sequencer. For example, it is assumed that a register is selected for executing an application. To switch this application to a next application, a selector switches the register to another register to be used in accordance with instructions from the sequencer after the application terminates. In this case, data inputted while the application was being executed remains in the register, so the next application can be executed immediately without exporting the data after the termination of the application.

Description

technical field [0001] The present invention relates to a reconfigurable processor and a semiconductor device, and more particularly to a reconfigurable processor and a semiconductor device including an ALU group comprising a plurality of ALUs and a sequencer. The sequencer described above is used to control the operation of the ALU group. Background technique [0002] Specification changes, function additions, new service additions, etc. may be made after the product is shipped. Traditionally, reconfigurable processors have been provided to change functionality without remanufacturing the device. A conventional reconfigurable processor can satisfy the above situation only by replacing circuit configuration information. [0003] For example, Digital Application Processor / Distributed Network Architecture (registered trademark) (DAP / DNA) manufactured by IP-Flex Corporation and Dynamically Reconfigurable Processor (DRP) manufactured by NEC Corporation are known such reconfigu...
