Abstract :
—Embedded processors are key building blocks for IoT
platforms. Such processors should provide flexible computing and
low-power consumption for the small form factor devices to have
better battery life. This paper introduces an implementation of a new
design for a 32-bit RISC embedded processor optimized for lowpower budget and targeting IoT applications. The proposed processor
is capable to execute a small set of simple instructions in few
cycles, and hence, efficient for low-power embedded applications.
The instruction set is inspired by the state-of-the-art Thumb-2 ISA
by ARM. The performance of the processor is analyzed in terms of
delay and power. The design is described in VHDL, implemented and
simulated on Vivado and tested using Nexys 4 DDR board featuring
Xilinx’s Artix-7 FPGA.
