Specifications

RTOS
- Real-Time Operating System
SCC
- Serial Communications Controller
The high performance module(s) within the CPM which implement the lowest layer of various serial
protocols, such as Asynchronous serial (UART), 10 Mbps Ethernet, HDLC etc.
SDMA
- Serial DMA
DMA used to transfer data to and from the SCCs.
SELF
- Simple Embedded Linux Framework
A simple default configuration for Embedded Linux systems that is suitable as starting point for building your
own systems. It is based on BusyBox to provide an init process, shell, and many common tools (from cat
and ls to vi), plus some other tools to provide network connectivity, allowing to access the system over the
internet using telnet and FTP services.
SIU
- System Interface Unit
Provides much of the external interfacing logic. It's the other major module on Motorola PowerQUICC
devices alongside the CPU core and CPM.
SMC
- Serial Management Controller
A lower performance version of the SCCs with more limited functionality, particularly useful for serial debug
ports and low throughput serial protocols.
SPI
- Serial Peripheral Interface
A relatively simple synchronous serial interface for connecting low speed external devices using minimal
wires.
S-Record
- Motorola S-Record Format
RTOS 209
