Dmitry Medvedev, TUSUR.

My background

• Microcontroller programming• Circuit design: schematics and printed circuit

boards (PCBs)• Integrated circuits design• Measuring apparatus• Digital signal processing (DSP)

What is SoC?

A system-on-a-chip is an integrated circuit that integrates all components of computer or other electronic system into a single chip.

SoC applications

What is unique about ARM architectures?

ARM-based chips can be found not only inside cell phones and tablet PC, but also set-top-boxes and game consoles.The main reasons of ARM popularity are:• relatively low cost• high performance• low power consumption.

FPGA is an integrated circuit designed to be configured by the customer or designer after manufacturing.

SoC and FPGA

FPGA structure

VHDL Example-- (this is a VHDL comment)-- import std_logic from the IEEE librarylibrary IEEE;use IEEE.std_logic_1164.all;

-- this is the entityentity ANDGATE is

port (I1 : in std_logic;I2 : in std_logic;O : out std_logic);

end entity ANDGATE;architecture RTL of ANDGATE is begin

O <= I1 and I2;end architecture RTL;
