ARM Architecture How to get through the ARM alphabet soup? Is it fast enough for my SDR?
What is ARM? ● Advanced ● RISC – Reduced – Instruction – Set – Computing ● Machine
Why is it so popular? ● One of the benefits of RISC – lower power usage. ● Many companies produce licensed solutions. ● Exists in all CPU market segments. ● Good software ecosystem. ● Cheap SoCs are available, capable of running Linux and Android.
Why is it good for a HAM? ● Cheap boards are available. ● Runs almost all Linux software. ● Can run on battery power. ● Has plenty of IO ports. ● Rugged enough to run in the field.
ARM Holdings ● Develops architecture, sells licenses to integrators producing System on Chips. ● Provides various license levels – from verified gate netlist to synthesizable RTL and architectural licenses. ● Price depends on perceived value. (Microcontroller cores cheaper than High performance)
Current general SoC core types ● Microcontroller – Cortex-M3, Cortex-M4 (STM32) ● Classic Raspberry Pi level boards - quad/dual-core ARM Cortex-A7 (BCM2836, A20) ● Modern ARM boards - quad/dual-core ARM Cortex- A72 + smaller cores (BCM2711, RK3399) ● High end boards – 32-core Vulcan (ThunderX2) ● Specialized GPU – 8-core Carmel + Nvidia Volta GPU (Xavier)
Raspberry Pi 4 ● Broadcom BCM2711 SoC with a 1.5 GHz 64-bit quad-core ARM Cortex-A72 processor ● Great community ● Camera accessory ● Widely available
ROCKPro64 ● Rockchip RK3399 SoC with Dual-Core Cortex-A72 and Quad-Core Cortex-A53 ● PCIe 4x slot ● eMMC storage ● LiPo socket ● Dual video output
A20-OLinuXino-LIME ● Allwinner A20 with dual core Cortex-A7 ● Industrial temp version -40C ... +85C ● 512MB DDR3 RAM ● eMMC storage ● LiPo socket ● Open source hardware ● Native SATA port
Orange Pi PC2 ● Allwinner H5 with quad core Cortex A53 ● 1GB DDR3 RAM ● 3x USB 2.0 ports + 1 OTG ● 20$ price tag ● HDMI port ● Mainline kernel support

ARM Architecture Guide for Ham Radio Projects

  • 1. ARM Architecture How to get through the ARM alphabet soup? Is it fast enough for my SDR?
  • 2. What is ARM? ● Advanced ● RISC – Reduced – Instruction – Set – Computing ● Machine
  • 3. Why is it so popular? ● One of the benefits of RISC – lower power usage. ● Many companies produce licensed solutions. ● Exists in all CPU market segments. ● Good software ecosystem. ● Cheap SoCs are available, capable of running Linux and Android.
  • 4. Why is it good for a HAM? ● Cheap boards are available. ● Runs almost all Linux software. ● Can run on battery power. ● Has plenty of IO ports. ● Rugged enough to run in the field.
  • 5. ARM Holdings ● Develops architecture, sells licenses to integrators producing System on Chips. ● Provides various license levels – from verified gate netlist to synthesizable RTL and architectural licenses. ● Price depends on perceived value. (Microcontroller cores cheaper than High performance)
  • 6. Current general SoC core types ● Microcontroller – Cortex-M3, Cortex-M4 (STM32) ● Classic Raspberry Pi level boards - quad/dual-core ARM Cortex-A7 (BCM2836, A20) ● Modern ARM boards - quad/dual-core ARM Cortex- A72 + smaller cores (BCM2711, RK3399) ● High end boards – 32-core Vulcan (ThunderX2) ● Specialized GPU – 8-core Carmel + Nvidia Volta GPU (Xavier)
  • 7. Raspberry Pi 4 ● Broadcom BCM2711 SoC with a 1.5 GHz 64-bit quad-core ARM Cortex-A72 processor ● Great community ● Camera accessory ● Widely available
  • 8. ROCKPro64 ● Rockchip RK3399 SoC with Dual-Core Cortex-A72 and Quad-Core Cortex-A53 ● PCIe 4x slot ● eMMC storage ● LiPo socket ● Dual video output
  • 9. A20-OLinuXino-LIME ● Allwinner A20 with dual core Cortex-A7 ● Industrial temp version -40C ... +85C ● 512MB DDR3 RAM ● eMMC storage ● LiPo socket ● Open source hardware ● Native SATA port
  • 10. Orange Pi PC2 ● Allwinner H5 with quad core Cortex A53 ● 1GB DDR3 RAM ● 3x USB 2.0 ports + 1 OTG ● 20$ price tag ● HDMI port ● Mainline kernel support
