SAM3S8/SD8 Summary
7.
Processor and Architecture
7.1
ARM Cortex-M3 Processor
Version 2.0
Thumb-2 (ISA) subset consisting of all base Thumb-2 instructions, 16-bit and 32-bit.
Harvard processor architecture enabling simultaneous instruction fetch with data load/store.
Three-stage pipeline.
Single cycle 32-bit multiply.
Hardware divide.
Thumb and Debug states.
Handler and Thread modes.
Low latency ISR entry and exit.
7.2
APB/AHB bridge
The SAM3S8/SD8 embeds One Peripheral bridge:
The peripherals of the bridge are clocked by MCK.
7.3
Matrix Masters
The Bus Matrix of the SAM3S8/SD8 manages 4 masters, which means that each master can
perform an access concurrently with others, to an available slave.
Each master has its own decoder, which is defined specifically for each master. In order to sim-
plify the addressing, all the masters have the same decodings.
7.4
Matrix Slaves
The Bus Matrix of the SAM3S8/SD8 manages 5 slaves. Each slave has its own arbiter, allowing
a different arbitration per slave.
