Qualcomm Snapdragon 675 Cortex-A76 based Processor Targets High-Tier Mid-Range Smartphones

Last August, Qualcomm unveiled Snapdragon 670 processor with performance and efficiency Kryo 360 cores believed to be based on Cortex-A75 and Cortex-A55 cores, but the company has just announced an update with Snapdragon 675 mobile platform powered by Kryo 460 cores which are based on Arm Cortex-A76 according to Anandtech, and so far, Cortex-A76 was only found in “premium” processors such as HiSilicon Kirin 980. Beside the upgrade cores, the company also claims the processor brings “outstanding gaming, a leap in artificial intelligence (AI) capability and a cutting-edge camera”. Snapdragon 675 main specifications: CPU 2x Kryo 460 (Cortex-A76 based) @ 2.0GHz with 256KB L2 6x Kryo 460 (Cortex-A55 based) @ 1.8GHz with 64KB L2 GPU – Adreno 612 DSP – Hexagon 685, Qualcomm AI Engine Display – Support for FHD+ display Camera – Spectra 250L ISP with triple-camera support Audio – Qualcomm aptX and Aqstic Modem – Snapdragon X12 LTE […]

Arm Cortex-A76AE Processor is Designed for Autonomous Driving Applications

Arm Cortex A76 processor core was first unveiled in June of this year, and very recently Hisilicon – part of Huawei – introduced Kirin 980 processor with four Cortex A76 cores, four Cortex A55 cores. Arm has now unveiled another variant of Cortex-A76 core. Cortex-A76AE (Automotive Enhanced) is designed for automotive application, and specifically autonomous driving applications, thanks to extra safety features such as Split-Lock capability which includes the ability for Dual Core Lock-Step (DCLS). The latter means that two processors are running the same code at the same time, and the instructions is only validated is the results are identical on both processors. Microarchitectural highlights of Cortex-A76AE for safety: Dual Core Lock-Step (DCLS) – The Cortex-A76AE is capable of running in Dual Core Lock-Step (DCLS), and hence is able to contribute towards a system’s ASIL D hardware diagnostic coverage requirements. Memory protection – The Cortex-A76AE supports Single Error Correction, […]

HiSilicon Unveils Kirin 980 Octa-core Cortex A76/A55 Processor with Mali-G76 GPU

Arm announced Cortex A76 CPU core and Mali-G76 GPU in June of this year, and in the past, we normally had to wait about a year between the announcement and the actual launch of SoC with the new IP core. But courtesy of HiSilicon (Huawei), we already know of one Cortex A76 processor with Kirin 980 processor featuring three clusters with two high performance Cortex A76 cores, two Cortex A76 cores clocked at a low frequency, and four Cortex A55 efficiency core. The company also added the new Mali-G76 GPU for good measure. Kirin 980 specifications and key features: CPU (DynamIQ clusters) 2x Cortex A76 cores @ up to 2.60 GHz with 512KB L2 cache 2x Cortex A76 cores @ up to 1.92 GHz with 512KB L2 cache 4x Cortex A55 cores @ 1.80 GHz with 128KB L2 cache 4MB shared L3 cache GPU – ARM Mali-G76MP10 @ 720 MHz […]
