2.3 Power Management Module
The Power Management module controls the power switches, under direction from the System Control Module.
2.4 Software-based Video Processing (SVP Core) Module
The SVP Core module is an asymmetric multi-core digital signal processor (DSP) engine that provides the full video
pipeline, further described in Video Pipeline, page 14.
2.5 Memory System (Memory Sys) Module
The Memory System module provides the memory interface to all the other modules that require access to SRAM
and/or OTP.
2.6 General Purpose Processor (GPP)
The GPP is a central processing unit (CPU) that provides the following functionality:
• Servicing of CCI commands
• Initialization and configuration of the video pipeline
• Power management
• Other housekeeping functions
2.7 Video Interface Module (Video IF)
The Video Interface module receives video data and formats it for VoSPI protocol (see documents in References,
page 6).
2.8 One-Time Programmable Memory (OTP)
The OTP memory contains all the non-volatile data for the camera, including the software programs for the SVP
Core and GPP as well as calibration data and camera-unique data (such as serial number). There are no provisions
for directly writing to OTP memory outside of the Lepton factory, except the User Default values as described
below.
An optional User Default feature is available on some Lepton versions to configure the desired defaults (e.g. FFC
mode, radiometry configuration, etc.), and write these defaults once by the user to OTP. This feature removes the
needs for an initialization sequence at start-up to configure the desired run-time settings. See User Defaults
Feature, page 42.
2.9 Static Random-Access Memory (SRAM)
SRAM is the primary volatile memory utilized by all other modules.
