Design Methodologies for Partially Recon gured Systems

Run-time reconguration (RTR) is an implementa-tion approach that divides an application into a series of sequentially executed stages with each stage imple-mented as a separate circuit module. Partial RTR ex-tends this approach by partitioning these stages and designing their circuit modules such that they exhibit a high degree of functional and physical commonal-ity. Transitioning between congurations can then be accomplished by updating only the dierences be-tween congurations. This reduces the amount of time that an RTR application spends conguring and sig-ni cantly enhances overall performance. This paper presents the design methodology for partial RTR in the context of RRANN2, a partial RTR articial neu-ral network.
