Abstract (in Japanese) (See Japanese page) 
(in English) In this article, we present a method for implementing external memory access within the context of binary synthesis utilizing commercial high-level synthesis systems. Binary synthesis, which translates binary program codes into hardware designs, enables synthesis of hardware from programs using assembly or inline assembly. Nakamichi et al. has proposed an approach for facilitating implementation of binary synthezers, in which binary programs are once translated into C programs and then processed by a high-level synthezer. However, binary synthesizers developed so far using this method embed memory within the synthesized hardware, thereby impeding data sharing among various hardware components and memory-mapped I/O. This paper aims to enhance Nakamichi's method to enable external memory access through I/O ports of synthesized hardware, facilitating memory-mapped I/O as well. A binary synthesizer, implemented based on the proposed method, demonstrates that external memory access and memory-mapped I/O are achievable without incurring significant overhead in terms of circuit size and execution cycle count.
