ARM You are presenting your new CPUS ARMV9 Cortex-A320 For IoT and edge applications, which would have an energy efficiency improvement of 50% over the previous generation.
ARMV9 Cortex-A320: CPUS for IoT and edge applications with 50% more efficiency
Cortex-A320 of ARM It will focus not only on performance, but also energy efficiency, always using architecture ARMV9, specially designed for IoT equipment and artificial intelligence.
The processor achieves an efficiency by 50% higher than the previous Cortex-A520which has been achieved based on new implementations, such as a narrow search and decoding data route, L1 cache and a reduced port registration file.
When the performance is compared with the previous Cortex-A35Intel assures that it offers a 30% higher performance, which has been achieved through efficient bifurcation predictors, prebuscadores and memory improvements.

These processors offer between 1 and 4 nuclei. These processors also have DSU-120t, a shared Dynamiq (DSU) unit that allows clusters only with Cortex-A320. These also have L1 caches up to 64 kb and l2 of up to 512 kbwith an AXBA5 AXI interface of 256 bits for external memory. The L2 cache and the TLB L2 can be shared between the CPU Cortex-A320. It is also commented on a vector processing unit with neon and SVE2 SIMD technologies, which can be used in a single nucleus or shared complex between nuclei.
The ARM Cortex-A320 admits new types of data such as BF16 and improved matrices multiplication instructions, which makes it more efficient for ML applications.
