Chapter: 4 4.3) Which of the following components of the program state are shared across threads in a multithreaded process? a. Register value b. Heap memory c. Global variable d. Stack memory Answer: The threads of a multithreaded process share heap memory and global variables. Each thread has its separate set of register values and a separate stack. 4.4) Output at LINE C is 5. Output at LINE P is 0. 4.6) What are the two differences between user-level and kernel-level threads

REAL TIME AND EMBEDDED SYSTEMS [ECWM611] Coursework 1: Report Submitted by: Louis Thompson TASK 1 (A) An embedded system contains the following independent software tasks: Control: The system performs closed-loop control of a robot. Loop processing takes 10 milliseconds. Alarm monitoring: A set of 5 alarm sensors are connected to the processor via a slow speed serial link. Each individual monitoring transaction (per alarm point) takes 10 milliseconds. It is assumed that all points

Pins 0 and 1 are connected to the respective pins of the ATmega8U2 USB-to-TTL Serial chip. ● External Interrupts: 2 (interrupt 0)‚ 3 (interrupt 1)‚ 18 (interrupt 5)‚ 19 (interrupt 4)‚ 20 (interrupt 3)‚ and 21 (interrupt 2). When there is a change in value‚ rising or falling edge or a low value the pins can be configured to trigger an interrupt. ● PWM: 0 to 13.Using Provide the analogWrite() function it an 8-bit PWM . ● SPI: 50 (MISO)‚ 51 (MOSI)‚ 52 (SCK)‚ 53 (SS).

embedded functions with flexible user programmable options‚ configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. The MMA8452Q has user selectable full scales of ±2g/±4g/±8g with high pass filtered data as well as non filtered data available real-time. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing

chapter 1 introduction 1.1GENERAL With the increasing denial of time and space the RFID technology is gaining momentum day by day. RFID is a source of identification of individuals and unique products. The budding technology RFID proves to threaten even the cloning technique‚ through the chip insertion. New ways of improving the existing RFID technology are being found and implemented. This advancement of RFID technology is looked beyond the security purposes. 1.2 PRESENT SCENARIO
