1. For each of the following three cases, classify if you would consider the device described as an embedded system or not. For each case use at least 2 of the characteristics given in class for what defines an "embedded system" and say whether the device meets them. (a) The iPhone 13. This phone has an Apple A15 Bionic processor in it. This processor is a six- core 64-bit CPU running up to 2.9GHz. It also includes a 16-core neural network accelerator capable of 11 trillion operations per second. It has 4GB of RAM and a powerful 4-core GPU (graphics unit) with 2532x1170 resolution. (b) You buy an electric toothbrush that has an 8-bit PIC16F1516 microcontroller (16MHz, 8k flash, 512 bytes RAM), an 8 LED display, an i2c pressure sensor, and a motor driven by an H- bridge. (c) You open up a microwave and it has an 8-bit PIC processor in it. This processor runs at 10MHz and the only interface is an LED display, a keypad, and some circuitry to operate the fans and magnetron. 2. You are designing a small embedded system. (a) Describe one reason why using a microcontroller might be better than using a micro-processor.
