INTRODUCTION TO LPC2210 AND LPC2294

• ARM core based architecture
• ARM7 local bus
• AMBA AHB/APB internal buses
• The main three blocks : platform, core and input / output peripherals
• APB Bridges
• Memory mapping, internal flash (2294) and SRAM

ARCHITECTURE OF THE ARM7TDMI CORE

• Presentation of the core, architecture and programming model
• Operating modes : user, system, super, IRQ, FIQ, undef and abort
• Pipeline, calculation of the CPI
• Effects of branches and exceptions on the performance
• ALU data path

SOFTWARE IMPLEMENTATION, V4T SPECIFICATION

• Parameterizing the linker to define sections
• Branch instructions, implementation of C call and return statements, long branch veneers
• ARM vs Thumb instruction sets, interworking
• ARM instruction set
• Inline barrel shifter
• Access to memory-mapped locations, addressing modes
• Arithmetical and logic instructions
• Thumb instruction set, highlighting restrictions with regard to ARM instruction set
• Compiler hints and tips, optimisations supported by RVCT
• Stack management
• Benefits of condition set capability in ARM state
• C-to-Assembly interface, ATPCS specification

EXCEPTION MECHANISM

• Reset
• FIQ vs IRQ
• Exception return instructions
• Latency estimation, impact of load and store multiple instructions
• Organization of the handler table, priority decoder, pre-emption and nesting
• ISR header and footer routines
• Development of a generic exception handler

INTEGRATED DEBUG FACILITIES

• JTAG interface
• Debug facilities, hardware breakpoint
• Executing code from RAM to take benefit of software breakpoints

THE VECTORED INTERRUPT CONTROLLER

• Assigning a priority to each interrupt source
• Steering external interrupts and local interrupts to either the core FIQ or IRQ
• Developing a generic interrupt handler performing nesting according to peripheral priorities defined by the user
• Integrated timers
• Using timers to understand the operation of the VIC

SYSTEM CONTROL

• Pin connect block
• Clocking
• Reset and wake-up timer
• Low power modes
• Watchdog timer
• Real-Time clock

ON-CHIP FLASH MEMORY (2294)

• Organization
• Erase sequence
• Program sequence
• In system programming via serial port
• On-chip bootloader

EXTERNAL MEMORY CONTROLLER

• Address decoding
• Chip-select registers
• Parameterizing the memory bank registers to support external burst flash

SERIAL INTERFACES
