AWR2944/AWR2944P Evaluation Module
Description
The AWR2944/AWR2944P evaluation module
(EVM) is an easy-to-use platform for evaluating
the AWR2944/AWR2944P mmWave system-on-
chip (SoC) radar sensor, which has direct
connectivity to the DCA1000EVM (sold separately).
The AWR2944EVM/AWR2944PEVM kit contains
everything required to start developing software
for the on-chip C66x digital signal processor
(DSP), ARM
®
Cortex
®
-R5F controller, and hardware
accelerator (HWA 2.0 in AWR2944, HWA 2.1 in
AWR2944P). Also included is onboard emulation for
programming and debugging, as well as onboard
buttons and LEDs for quick integration of a simple
user interface.
