Read-only Memory

Type of non-volatile memory used in computers. Once data is written to ROM, the data cannot be removed and can only be read.

RTSC
Real Time Software Components

A toolset for creating reusable code, used by TI-RTOS. See RTSC and RTSC-Pedia.

SysConfig
System Configuration Tool

SysConfig is a graphical interface for configuring software projects. Configuration files, C source files and header files are generated based on the parameters configured in the SysConfig dashboard. See Get started with SysConfig.

TI-CLANG
TI Arm Clang Compiler Toolchain

The TI Arm Clang Compiler Toolchain (tiarmclang) is the next generation TI Arm compiler, replacing the previous TI Arm Compiler Tools (armcl). You can use the tiarmclang compiler toolchain to build applications from C, C++, and/or assembly source files to be loaded and run on one of the Cortex-M or Cortex-R Arm processors that are supported by the toolchain. You can find more information here.

VIMS
Versatile Instruction Memory System

A system control module that handles access to the device memory areas from the CPU and system bus. You can read more in the CC13x2 CC26x2 SimpleLink Wireless MCU Technical Reference Manual.

.bss

Block started by symbol. This memory section usually contains uninitialized variables including the task stacks.

Sensor Controller Terms and Acronyms

SC
Sensor Controller

A dedicated 16-bit CPU core on CC13xx and CC26xx devices, located in the auxiliary (AUX) power/clock domain. It can perform simple background tasks autonomously and independently of the System CPU and the MCU domain power states.

SCS
Sensor Controller Studio

A stand-alone IDE used to write, test and debug code for the Sensor Controller.

RF Core Terms and Acronyms

CCA
Clear Channel Assessment

CCA referrs to checking if a channel is clear of traffic before transmitting. The combination of RSSI threshold and channel idle time defines what is considered a “clear” channel.

CPE
Command and Packet Engine

The unit on the RF core that is responsible for command execution and packet encoding/decoding. It acts as a supervisor for all other sub-modules during command execution.

genfsk

Used as an abbreviation for settings that uses the patch rf_patch_cpe_genfsk. genfsk supports up to 500 kbps FSK and GFSK.

IB
Current Bias

One of several parameters for adjusting output power during packet transmissions. ‘I’ in ‘IB’ stands for the SI unit for current.

MCE
Modem Control Engine

A functional unit on the RF core that sits in between the CPE and the RFE. It is responsible for signal modulation/demodulation and binary base band processing.

PA
Power Amplifier

A RF power amplifier converts a low-power RF signal into a higher power signal. Typically, RF power amplifiers drive the antenna of a transmitter.

RAT
Radio Timer

A functional unit on the RF core that provides accurate timing for command execution. It runs with 1/4 speed of the high- frequency oscillator.

RFE
Radio Front-end Engine

A functional unit on the RF core that is responsible for the analog signal processing part. It connects the MCE to the antenna.

SLR

RF mode designed to giv a long range. The data rate is 5 kbps.

Over-the-Air Download (OAD) Terms and Acronyms

BIM
Boot Image Manager

A bootloader that runs after the device’s ROM startup code. The BIM is responsible for analyzing the image header of all images and determining the most suitable image to run. Once the BIM has found the proper image, it will jump to it’s program entry.

CRC
Cyclic Redundancy Check

An error-detecting code used to check the integrity of blocks of data.

ECDSA
Elliptic Curve Digital Signature Algorithm

A variant of the Digital Signature Algorithm (DSA) which uses elliptic curve cryptography.

Factory Image

The factory image is a “golden” image that resides in external flash as a fail-safe mechanism.

HIB
Halt In Boot

A mechanism in CC13xx or CC26xx to ensure that the external emulator can take control of the device before it executes any application code.

OAD
Over-the-Air Download

The process of performing a device firmware update over the air.

OAD Target

The device whose firmware is being upgraded over the air. This is assumed to be a CC26xx or CC13xx device running the TI protocol-specific transport for OAD.

OAD Distributor

The device responsible for accepting an OAD enabled image from the compiler and transferring it over the air to the OAD Target.
