AMBA AMBA ( Advanced Microcontroller Bus Architecture )It is an open-standard, on-chip interconnect specification for the connection andmanagement of functional blocks in system-on-a-chip (SoC) designs. ASB (Advanced System Bus):Simple bi-directional bus APB (Advanced Peripheral Bus) :Low speed peripheral bus AHB (Advanced High speed Bus): AHB multi: AHB lite:Centralized multilayer busMulti master – multi slaveSingle master – multi slave Mostly ARM core is Bus master and Peripherals are slaves05-01-2017ARM Processors - Introduction toEmbedded System14
Peripherals All peripherals are Memory mapped Controllers are special types of peripherals that govern the interfacing policies Interrupt controller Standard Interrupt control Vector Interrupt Control (VIC)-No PriorityPriority based Memory controller Memory preparation Ex : DRAM requires to be configured for refresh rates and timing before itis accessed Memory management Memory protection05-01-2017ARM Processors - Introduction toEmbedded System15

Embedded Software Boot / initialization codeIt runs on reset and does following basictasks Initial hardware configuration likememory controllers and cache i.e., itprepares the hardware to satisfy theimage to be booted Diagnostics : Fault detection andisolation Booting: Loading image andhanding over the control to image bymodifying the PC(Program Counter)05-01-2017ARM Processors - Introduction toEmbedded System17
Embedded Software Operating SystemOrganizes system resources like peripherals, memory and processors time Two main categories Real Time Operating Systems (RTOS) Hard real time Soft real time Platform Operating SystemsManages large non real time applications ApplicationsCode dedicated to handle a particular task05-01-2017ARM Processors - Introduction toEmbedded System18
