Abstract

Rice is source of food calories and protein.  This second most widely grown cereal crop is the staple food for more than half the world’s population especially in developing countries.  The ability of global rice production to meet population demands (now estimated at more than 5 billion and projected to rise to 8.9 billion by 2050) remains in uncertainty in the near future unless challenges in rice production are properly addressed [1-3]. This paper proposed an IoT (Internet of things)-based paddy productivity monitoring and advisory system Using Dash7 Wireless Network Protocol. All collected data will be stored in a database management system to enable users to retrieve data either from tablets, smartphones or computers. The heart of the system is the ATmega328p microcontroller that will control the payload of the wireless network of dash7 and read data from sensor nodes. Results show all data from sensor nodes in representation of graph for analysis purpose.

Abstract

In this paper, a Real Time Clock (RTC) system for a dedicated microcontroller is proposed to provide the customized microcontroller its own time and date system. The RTC is developed using Verilog Hardware Description Language (HDL) and simulated using Synopsys software. This RTC is developed with standard Advance Peripheral Bus (APB) to be interfacing with the microcontroller through Advanced Microcontroller Bus Architecture (AMBA). This RTC will be used as an on-chip RTC in the microcontroller system to provide precise time and date which can be used for various applications. The basic architecture of RTC, APB standard for interfacing the RTC with AMBA bus, and the result in term of RTL, waveform, and layout will be discussed in this documentation. For this research, the part covered is on the logic part of the RTC that is bus interface, register, frequency divider and counter.

Abstract

Dramatic rises in power density and die sizes inside system-on-chip (SoC) design have led to the thermal issue. High temperatures or uneven temperature distributions may result not only in reliability issues, also has become the biggest issue that can limit the system performance.  This paper presents the design and simulation of a temperature-based digital signal processing unit for modern system-on-chip design using the Verilog HDL. This design provides continuous monitoring of temperature and reacts to specified conditions. The simulation of the system has been done on Synopsys Software. The result showed that temperature monitoring process is within the temperature range due to the incorporation of an interrupt-based system and with an advantage of minimum chip area required.
