History

The Cortex-A34 is a processor designed by ARM Holdings for use in a wide range of devices, including smartphones, tablets, and other embedded systems. It was first announced in 2020, and is based on ARM’s 64-bit AArch64 architecture, which is designed for efficient execution of both 32-bit and 64-bit applications.

The Cortex-A34 is an update to the Cortex-A35 processor, which was introduced in 2017. It builds upon the design of the Cortex-A35, adding new features and improvements to increase performance and efficiency.

Architecture

The Cortex-A34 is based on ARM’s 64-bit AArch64 architecture, which is designed for efficient execution of both 32-bit and 64-bit applications. It is a mid-range processor that is designed to provide a good balance between performance and power efficiency.

The Cortex-A34 includes a number of features to help improve performance and efficiency, including a wide execution engine, a branch predictor, and a hardware accelerator for vector operations. It also includes support for ARM’s big.LITTLE architecture, which allows the processor to switch between different processor cores depending on the workload, allowing it to use high-performance cores when needed and low-power cores when possible to conserve energy.

Features

• 64-bit AArch64 architecture
• Support for ARM’s big.LITTLE architecture
• Low power consumption
• Small die size and low gate count
• Support for ARM’s TrustZone technology

Benefits

• Good balance between performance and power efficiency
• Suitable for use in a wide range of devices
• Low power consumption allows for long battery life
• Small die size and low gate count reduce manufacturing costs
• TrustZone technology provides security for sensitive applications

Description of Block Diagram

Add-Ons

Possible add-ons for the Cortex-A34 processor include:

• NEON technology: NEON is a SIMD (Single Instruction, Multiple Data) extension that can accelerate the execution of multimedia and signal processing tasks.
• Hardware virtualization: Hardware virtualization allows multiple operating systems to run on the same processor.
• TrustZone technology: TrustZone allows the processor to execute code in a secure, isolated environment to protect against attacks and tampering.

Usage

The Cortex-A34 was first used in a range of devices, including smartphones and tablets, in 2020. It is currently used in a variety of devices that require low power consumption and a good balance of performance and efficiency, such as smart home devices, wearable technology, and other embedded systems. The Cortex-A34 was first used in the MediaTek Helio A22, a budget smartphone that was released in 2018.
