What is ARM Cortex r5f?
The Arm Cortex-R5 processor provides extended fault containment for real-time applications. The Cortex-R5 processor builds on the feature set of the Cortex-R4 with enhanced error management, extended functional safety, and SoC integration features for use in deeply embedded real-time and safety-critical systems.
What is R5 core?
The Cortex-R series of cores from ARM focus on real-time applications. The R5 adds dual-core asymmetric multi-processing (AMP) configuration and the R7 has asymmetric or symmetric multi-processing. The two new models add a snoop control unit (SCU) for de-bug.
Where are Cortex-R processors used?
The Cortex-R processors target high-performance real-time applications such as hard disk controllers (or solid state drive controllers), networking equipment and printers in the enterprise segment, consumer devices such as Blu-ray players and media players, and also automotive applications such as airbags, braking …
What is VFPv3?
VFPv3. An optional extension to the Arm, Thumb, and ThumbEE instruction sets in the Armv7-A and Armv7-R profiles. VFPv3 can be implemented with either 32 or 16 doubleword registers. VFPv3U is a variant of VFPv3 that supports the trapping of floating-point exceptions to support code. VFPv3 with Half-precision Extension.
What is R7 ARM?
Specifications. The Cortex-R7 processor features an 11-stage, superscalar, out-of-order pipeline with dynamic and static branch prediction, dynamic register re-naming and non-blocking Load-Store Unit.
What is FPU in microcontroller?
Stands for “Floating Point Unit.” An FPU is a processor or part of a processor that performs floating point calculations. Any mathematical operation, such as addition, subtraction, multiplication, or division can be performed by either the integer processing unit or the FPU.
What is r11 in ARM?
Register r11 by convention is used as the frame pointer fp. The point of this is to save the return address and the frame pointer of the calling function so we can properly return when this function is over. The frame pointer is set to. fp = sp + 4. The frame pointer is used as a reference for local stack variables.
How is DMIPS calculated?
Calculate for DMIPS DMIPS (Dhrystone MIPS ). It is obtained when the Dhrystone score is divided by 1757 (the number of Dhrystones per second obtained on the VAX 11/780, nominally a 1 MIPS machine).
