Raspberry Pi, This tutorial is about the Voice Recording and Test to speech Using Raspberry Pi. But First, let's have a small introduction about Raspberry Pi. Introduction Raspberry Pi 3 Model B System on Chip(SoC) What is System on Chip? - A complex IC that integrates the major functional elements into a single chip or chipset. Programmable processors On-chip memory Accelerating function hardware (e.g. GPU) Both hardware and Software Analog components Benefits of SoC - Reduce overall system cost - Increase performance - Lower power consumption - Reduce size Soc in Raspberry Pi: Broadcom BCCM2835 SoC Multimedia Processor CPU - ARM 1176JZF-S (armv6k) 700MHz - RISC Architecture and low power draw - Not compatible with traditional PC software GPU - Broadcom Video IV -
