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 CC13x0 CC26x0 SimpleLink Wireless MCU Technical Reference Manual.

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 running on the OAD Client.
HIB

OAD Client
The device receiving firmware images from an OAD Server.
OAD Server
The device responsible for distributing new firmware images.
SNV
Simple Non Volatile. An abstraction layer used by the BLE stack for reading and writing to non volatile memory. The GAPBondMgr layer of stack uses SNV to store keys. This region can also be used by the user.
