   * - Term
     - Definition
   * - Palette
     - Sima’s suite of software tools for AI model development, video pipeline creation, SoC
       software, operating systems, and all software going into SiMa’s hardware
   * - Palette Edgematic
     - Sima’s visual tool for evaluating AI/CV application deployment through SiMa’s hardware
       and software
   * - Model
     - A software that can be trained to perform a cognitive task like a human being. For example,
       vision or speech analysis 
   * - Application (pipeline)
     - An application in AI/CV includes processes that need to be performed from sensor data
       ingestion to actual inference output. This involves pre-processing and post-processing of
       images and video streams
   * - Plugin
     - A software or hardware component that can be part of an AI/CV application to accomplish
       a very specific task viz. H.264 standard based decoder
   * - Stream
     - A continuous flow of audio/visual content. For AI/CV this often involves a video feed from a
       source such as a Real-Time Streaming Protocol (RTSP) server over Ethernet
   * - MLA
     - SiMa’s machine learning accelerator block for running AI inferencing
   * - SoC
     - System-on-Chip
   * - Allegro
     - Block inside SiMa’s SoC responsible for video encoding/decoding
   * - EV74
     - Digital signal processor (DSP) block inside Sima’s SoC
   * - A65
     - ARM® processor responsible for running software and coordinating activities on EV74 and the MLA
