GraniteCore a.k.a. GC is the motor control core developed for Granite Devices motor drives such as [[Argon (servo drive)|Argon]], [[IONI]] and [[ATOMI]].

== GraniteCore variants ==
Due to underlying hardware differences, the GraniteCore has several variants that also have certain differences in functionality and parameterization.

GraniteCore major variant numbers such as G2.x together very similar from user perspective, however some differences exists and these are identified in parameter descriptions in [[Granity user guide]].

Note that GraniteCore variant is fixed to underlying hardware type, it is ''not'' same as firmware version and variant will not change in firmware upgrades.

==About Argon architecture==
Argon consists dual CPU architecture which run in tight synchronism and have different tasks:
;GraniteCore
*Servo control functionality for torque, velocity and position control
*[[High dynamic range torque control]]
*[[Dead-time distortion|Dead-time distortion correction]]
*Control power stage directly
*Axis homing functionality
*Virtual scope to capture variables at high sample rate
*Galvanically isolated from I/O side
*Based on Digital Signal Controller
;I/O side CPU
*Feed GraniteCore with real time data consisting
**Position & velocity feedback device data
**State of physical inputs (enable, clear faults, hall sensors etc)
**SimpleMotion V2 commands to read/write parameters
*Interface different types [[Feedback devices|feedback devices]] and [[Setpoint signal|setpoint inputs]]
*Handle SimpleMotion V2 communication
*Display device state via digital outputs and [[Argon LED indicators|LED indicators]]
*Based on ARM Cortex M3 microcontroller running at 120 MHz
===Benefits of the architecture===
*I/O side CPU has [[Argon open source firmware|open source firmware]] allowing end users to implement additional drivers for feedback devices and/or create stand-alone servo drive applications without external [[Controller]].
*Isolation between the processors is more cost efficient and flexible than isolation individual I/O signals directly to high voltage side (a typical solution in the market)
