领域内可重构功能单元自动生成方法

Automatic Generation of Domain-specific Reconfigurable Function Units

特殊功能单元可以有效加速处理器性能,然而由于其专用性,能够加速的应用有限。领域内可重构功能单元提供领域内的灵活性与高效性。文章提出针对特定应用领域生成可重构能单元的方法,该方法基于多个表达式自动生成高效的可重构功能单元。选取传输触发体系结构作为平台,在密码领域中三类算法的应用验证了该方法的有效性。

Special function unit can efficiently enhance the microprocessor＇s perfornianee, but the applications that can be accelerated are limited because of its customization. Domains specific reconfigurable filnction unit （DSRFU） can still speedup the applications, while providing domain flexibility. This paper presents a method, which can generate high quality DSRFUs from muhi-expression. Choosing transport triggered architecture as a platform, applying this method to cipher domain validates its efficiency.
