The paper introduces an internet-based remote prototyping platform for accelerator applications. It gives an overview on the Xputer prototype Map-oriented Machine with Parallel Data Access (MoM-PDA), which operates as an accelerator to a host computer. The MoMPDA utilizes the coarse-grained KressArray and implements concurrent data access to parallel memory banks. To give a large user community the opportunity to access the MoM-PDA prototype this paper describes how it can be connected to an Internet-based development system. This development system enables worldwide access to the prototype via the Internet.
