Arm has just announced its 2020 Arm Mobile IP portfolio with no less than five IP blocks including Arm Cortex-A78 CPU, Arm Mali-G78 and G68 GPUs, Arm Ethos-N78 neural processing unit, and the custom Cortex-X program starting with Cortex-X1, the most powerful Arm core to date. Arm Cortex-A78 CPU Cortex-A78 highlights: Architecture – Armv8-A (Harvard) Extensions – Armv8.1, Armv8.2, Cryptography, and RAS; Armv8.3 (LDAPR instructions only) ISA support – A64, A32, and T32 (at EL0 only) Microarchitecture Pipeline – Out of order Superscalar Neon / Floating Point Unit Optional cryptography Unit Max number of CPUs in cluster – 4 Physical Addressing (PA) – 40-bit Memory system and external interfaces 32KB to 64KB L1 I-Cache / D-Cache 256KB to 512KB L2 Cache Optional 512KB to 4MB L3 Cache ECC and LPAE support Trustzone security Cortex-A78 delivers 20% extra performance compared to Cortex-A77 at the same power budget (one Watt), but peak […]
