Dear Expert,

I need help answering these questions

Embedded Systems EEL 4742 Homework 4: The ARM v7-M Architecture For the purposes of this homework, you will be examining the ARM architecture. ARM Holdings the company behind the architecture, is a fabless semiconductor company. That is, ARM Holdings does not fabricate or sell processors, instead they license their processor IP to other vendors for them to design and fabricate system on chips. Customers of ARM Holdings include Atmel, Ap ple, Freescale, nVidia, Qualcomm, Samsung, STMicroelectronics, Texas Instruments, and Toshiba Customers are allowed to extend ARM Holdings' original design adding new architectural elements For example, Tegra X1 chips by nVidia include four ARM Cortex-A57 cores alongside four ARM Cortex-A53 cores operating in big. LITTLE model, a Maxwell-based GPU (this type of GPU is also found in the GeForce GTX 970), and hardware accelerators for video encoding and decoding, among other peripherals Currently, ARM Holdings divides their processor lineup into the Cortex-A series, Cortex-R series and Cortex-M series. The Cortex-A series are application processors. These are fully featured processors that include the full ARM instruction set and extensions and a memory management unit. The Cortex-R, series are processors which have been optimized for real-time and safety critical applications, providing extra features such as error-correcting code (ECC) at the L1 cache and busses and fault tolerance The Cortex-M processors are designed for microcontroller usage These cores usually work with the reduced Thumb and Thumb-2 instruction sets, and most CPU peripherals such as the memory protection unit are optional In this homework, you will be looking at the ARM Cortex-M4 processor core. The ARM Cortex- M4 processor is based around the ARM v7-M architecture. Current system on chips utilizing this processor core include the Texas Instruments MSP432P401R, which combines the traditional MSP430 peripherals with some ARM-specific peripherals, and a Cortex core. To answer the following questions, you should look at the documents ARM Cortez-MA Processor Technical Reference Manual, ARM v7-M Architecture Reference Manual, and any other resources in ARM Holdings' website Embedded Systems EEL 4742 Homework 4: The ARM v7-M Architecture For the purposes of this homework, you will be examining the ARM architecture.
