 # Marmot RISC-V SoC
 
+  
+
 ## A Customizable RISC-V Microcomputer
+
 A custom microcomputer design is useful when off-the-shelf general-purpose microcontrollers fail to meet the system needs. The rocket SoC generator automatically generate an SoC. It circumvents labor-intensive, error-prone, top-level SoC design.
 
+  
+
 ## SoC Customization Flow
+
 The Rocket SoC Generator and Caravel SoC Template are reused to create a twin (not identical) RISC-V SoC consisting of one Rocket RISC-V and one Caravel RISC-V. The objectives here is to save hours on design verification and reduce power consumption rather than saving die area or chip cost.
