What is big little processor?
Arm big. LITTLE technology is a heterogeneous processing architecture that uses two types of processor. ”LITTLE” processors are designed for maximum power efficiency while ”big” processors are designed to provide maximum compute performance. With two dedicated processors, the big.
What is a little core?
The ‘big’ core is used when the demand is high and the ‘LITTLE’ core is employed when demand is low.
What is ARMv7 ARMv8?
The ARMv7 architecture is the basis for all current 32-bit ARM Cortex™ processors, including the Cortex-A15 and Cortex-A9 processors. The ARMv8 architecture is the first ARM architecture that includes 64-bit execution, enabling processors based on the architecture to combine 64-bit execution with 32-bit execution.
What is ARM DynamIQ?
Arm DynamIQ technology redefines the multi-core experience from edge to cloud across a secure, common Total Computing platform. Arm CPUs power the incredible experiences in personal devices today, transforming how we work and play. It combines the big and LITTLE CPUs into a single, fully-integrated cluster.
Who developed x86?
Intel
x86 is a family of instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant.
What is heterogeneous multi processing?
The term Heterogeneous multi-processing (HMP) finds application in many different contexts. ARM uses HMP to mean a system composed of clusters of application processors that are 100% identical in their instruction set architecture but very different in their microarchitecture.
What is Cache stashing?
Cache stashing allows an external agent to request that a line is brought (or stashed) into a cache. Cache stashing can either be performed over the ACP interface, or the CHI master interface. Stash requests can target the L3 cache, or any of the L2 caches of cores within the cluster.
What is CPU DSU?
About the DSU The DynamIQ Shared Unit (DSU) comprises the L3 memory system, control logic, and external interfaces to support a DynamIQ cluster. The DynamIQ cluster microarchitecture integrates one or more cores with the DSU to form a cluster that is implemented to a specified configuration.
