Development of Filled Circle Drawing in High-Level Synthesis Oriented Game Programming Library

We are developing a high-level synthesizable software game library to realize high performance and low power mobile terminals executing game applications. High-level synthesis, HLS, is a technology that automatically converts software into hardware. Games developed by HLS oriented game software library are executed by high-speed and low-power hardware reconfigured on reconfigurable devices in mobile terminals. This paper develops a circle drawing processing as one of functions in HLS oriented game software library. We employ Michener's algorithm which is suitable for hardware implementation as a circle drawing algorithm because it just consists of simple integer operations. We also show the program description method so that HLS tool can convert the circle drawing processing based on Michener's algorithm to a good hardware module. The experiments evaluate the execution time and the amount of hardware of the hardware module HLS generated.
