RF Core Terms and Acronyms¶
- 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.
- 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.
- 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.
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 determing the most suitable image to run. Once the BIM has found the proper image, it will jump to it’s program entry.
- Factory Image
- The factory image is a “golden” image that resides in external flash as a failsafe mechanism.
- 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 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.
Dynamic Multi-protocol Manager Terms and Acronyms¶
- Dynamic Multi-protocol Manager
- DMM
- An arbiter between multiple protocol stacks that are sharing the multi mode RF driver and thus the radio. The DMM aides in scheduling radio operations by way of application provided state information and timing constraints.
