Microcontroller for the logic tasks
(National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2021) Sergiyenko, Anatoliy; Molchanov, Oleksii; Orlova, Maria
A new SM16 microcontroller architecture is proposed which is intended for the logic-intensive applications in the field-programmable gate array (FPGA). The microcontroller has the stack architecture which provides the implementation of the most of instructions for a single clock cycle. The short but fast programs are derived due to the 16-bit instructions, which code up to three independent operations, and intensive use of the threaded code style. The framework is developed which compiles the program, simulates it, and translates to the ROM. The developed SM16 core with additional three-stack blocks, hash-table, and instructions that accelerate the execution of parsing operations is used for efficient XML-document processing and can be frequently reconfigured to the given document grammar set. The parsing speed equals to one byte per 24 clock cycles.
