Is armv7l 32 or 64 bit?

Solution 1:

armv7l is 32 bit processor.

If you need a little bit more information regarding ARMv8, please read @Rinzwind's answer :-)

Solution 2:

ARMv8 is 64-bit. With 32-bit compatibility.

The ARMv8 architecture introduces 64-bit support to the ARM architecture with a focus on power-efficient implementation while maintaining compatibility with existing 32-bit software. By adopting a clean approach ARMv8-A processors extend the performance range available while maintaining the low power consumption characteristics of the ARM processors that will power tomorrow's most innovative and efficient devices. ARM has 3 different product tiers supporting the ARMv8-A architecture: High Performance, High Efficiency, and Ultra-High Efficiency.

ARMv8-A introduces 64-bit architecture support to the ARM architecture and includes:

• 64-bit general purpose registers, SP (stack pointer) and PC (program counter)
• 64-bit data processing and extended virtual addressing

Two main execution states:

• AArch64 - The 64-bit execution state including exception model, memory -model, programmers' model and instruction set support for that state
• AArch32 - The 32-bit execution state including exception model, memory model, programmers' model and instruction set support for that state

Anything lower (like ARMv7) is 32-bit.
