A “short list” of embedded systems

CS269: HW/SW Engineering of Embedded Systems, Winter02

Architecture

Architecture: abstracted layers for smooth refinement

SYSTEM:

- SW modules, HW

- bounded FIFO, lossy channels

- no address, bus independent

TRANSACTION:

- address, data split in chunk

- no detailed bus protocol or width

PHYSICAL:

- specific bus protocol

- detailed RTOS characterization
