Application Specific Instruction-set Processors (ASIPs) expose to the designer a large number of degrees of freedom. Accurate and rapid simulation tools are needed to explore the design space. To this aim, FPGA-based emulators have recently been proposed as an alternative to pure software cycle-accurate simulator. However, the advantages of on-hardware emulation are reduced by the overhead of the RTL synthesis process that needs to be run for each configuration to be emulated. The work presented in this paper aims at mitigating this overhead, exploiting a form of software-driven platform runtime reconfiguration. We present a complete emulation toolchain that, given a set of candidate ASIP configurations, identifies and builds an overdimensioned architecture capable of being reconfigured via software at runtime, emulating all the design space points under evaluation. The approach has been validated against two different case studies, a filtering kernel and an M-JPEG encoding kernel. Moreover, the presented emulation toolchain couples FPGA emulation with activity-based physical modeling to extract area and power/energy consumption figures. We show how the adoption of the presented toolchain reduces significantly the design space exploration time, while introducing an overhead lower than 10% for the FPGA resources and lower than 0.5% in terms of operating frequency. 1. Introduction The genus Hydrocyphon Redtenbacher is represented by 100 species divided into 13 species groups from the Palaearctic and the Oriental Regions (see, e.g., [1, 2] and Tables 1 and 2). The larvae of this genus inhabit running water, for example, small rivers and streams, and the adults are frequently collected by sweeping around the larval habitat. The genus is well defined by certain characteristics (e.g., small body, deeply notched anterior margin of the mesosternum, well-developed parameres and parameroids), and has been comparatively well studied taxonomically [1, 2]. In the present paper, I describe seven new species from Indonesia, Thailand, Malaysia, and India. In addition, new combination and additional specimens examined are presented.
