Two instruction sets
–ARM
high-performance 32-bit instruction set
–Thumb
high code density 16-bit instruction set
Three-stage pipeline architecture
– Instruction Fetch (F)
– Instruction Decode (D)
– Execute (E)
7.2
Debug and Test Features
Integrated embedded in-circuit emulator
– Two watchpoint units
– Test access port accessible through a JTAG protocol
– Debug communication channel
Debug Unit
–Two-pin UART
– Debug communication channel interrupt handling
– Chip ID Register
IEEE1149.1 JTAG Boundary-scan on all digital pins
7.3
Memory Controller
Programmable Bus Arbiter
– Handles requests from the ARM7TDMI, the Ethernet MAC and the Peripheral DMA
Controller
Address decoder provides selection signals for
– Three internal 1 Mbyte memory areas
– One 256 Mbyte embedded peripheral area
Abort Status Registers
– Source, Type and all parameters of the access leading to an abort are saved
– Facilitates debug by detection of bad pointers
Misalignment Detector
– Alignment checking of all data accesses
– Abort generation in case of misalignment
Remap Command
– Remaps the SRAM in place of the embedded non-volatile memory
– Allows handling of dynamic exception vectors
