In 2015, ARM introduced an energy-efficient 64/32-bit core. for the heterogeneous big.LITTLE architecture, and in 2016, released a 32-bit core. for wearable electronics.
And now, without drawing much attention, the company has introduced the 64-bit Cortex-A34 core. This product is offered under the Flexible Access program, which provides chip developers access to a broad range of intellectual property, allowing them to only pay for the blocks that will be used in the final product.
This is the only Cortex processor, alongside the Cortex-A65, that supports only 64-bit instructions and is incompatible with 32-bit code. Cortex-A34 is based on the ARMv8-A architecture, features an 8-stage pipeline, supports symmetric multiprocessing (SMP) with up to 4 cores in a single cluster, and multiple consecutive clusters of SMP processors connected via an AMBA 4 bus. The amount of distributed Level 2 cache may reach 1 MB, including ECC error correction.
Support for TrustZone security technology, hardware virtualization, DSP extensions, SIMD (NEON), and low-cost floating-point computation VFPv4, as well as a comprehensive library of components for debugging and tracing functions in CoreSight SoC-400, is available.
ARM states that the Cortex-A34 will be used in various applications, including industrial devices, smart home electronics, healthcare, and cloud computing. The abandonment of 32-bit instructions is sure to reduce the cost of the final chip.
