Abstract :
The paper presents a prototype at 8-bit RISC microcontroller, called OctaLynx, with 16-bit address bus. It consists of the core (with instruction decoder, arithmetic logic unit and interrupt control unit) and some peripherals (three 8-bit general purpose input-output ports, timers/counters, USART, SPI). The prototype uses external memory. The OctaLynx behavior is described by means of Verilog hardware description language. It has been implemented in Microsemi (i.e. Actel) IGLOO nano AGL250 device. Some tests were carried out.
