CHiPReP—A Compiler for the HiPReP High-Performance Reconfigurable Processor

This article presents CHiPReP, a C compiler for the HiPReP processor, which is a high-performance Coarse-Grained Reconfigurable Array employing Floating-Point Units. CHiPReP is an extension of the LLVM and CCF compiler frameworks. Its main contributions are (i) a Splitting Algorithm for Data Dependence Graphs, which distributes the computations of a C loop to Address-Generator Units and Processing Elements; (ii) a novel instruction clustering and scheduling heuristic; and (iii) an integrated placement, pipeline balancing and routing optimization method based on Simulated Annealing. The compiler was verified and analyzed using a cycle-accurate HiPReP simulation model.

“Yes, the type of student supervision matters, but what about the placement structure?” - A critical realist review of block and integrated practice learning models within pre-registration nursing programmes

This paper highlights the importance of effective clinical experiences for pre-registration nursing students and the wealth of published work associated with practice learning, particularly regarding approaches to student supervision during a practicum. It draws attention to frequent calls within nursing literature for longer placements; many of which fail to either identify the perceived benefits of such change or state whether a longer practicum should involve increased practice learning hours or redistribute existing hours over an extended period; key omissions given the resource-intensive nature of providing these educational opportunities. It also highlights a paucity of research regarding the effect of placement duration and intensity on clinical learning and that practicum design is commonly shaped by custom, practice, operational and financial considerations rather than a sound educational rationale. A Critical Realist review of studies associated with two fundamental placement structures, the block, and integrated models, is offered to consider their strengths and limitations. Moreover, work that evaluates initiatives offering students paid employment in caring roles undertaken alongside a pre-registration programme and therefore displaying similarities to the integrated practice learning model are examined. The review concludes that, as yet, there is insufficient empirical evidence to recommend the targeted application of either a block or integrated placement model within any specific part of a pre-registration nursing programme, calls for greater consistency in the language of placement structure and outlines the author’s own current work contributing to the extremely limited body of knowledge available regarding this aspect of curriculum design within nurse education.
