Arm v8

Codasip has put support for a set of instruction extensions intended to secure memory into its RISC-V core designs.

Arm is to return to focusing on semiconductor IP following the decision to spin out its IoT operations to separate groups within the Softbank empire.

ARM has pulled together a number of forthcoming changes to its Cortex processor and Big-Little cluster architectures under the umbrella title DynamIQ, claiming they will support the increasing use of AI algorithms in servers and embedded control.

ARM is bringing the Trustzone security architecture to future Cortex-M processor cores, combining that with a version of AHB that will recognise the difference between secure and non-secure transactions.

Cadence Design Systems has signed up for a licence to ARM cores that will let the EDA supplier optimize support for 32bit and 64bit Cortex processors in its tools.
