ARMv8-M Architecture Simplifies Security for Smart Embedded Devices; Arm Holdings; November 10, 2015. To determine which components have been included in a particular ARM CPU chip, consult the manufacturer datasheet and related documentation. The Cortex-M3 adds three Thumb-1 instructions, all Thumb-2 instructions, hardware integer divide, and saturation arithmetic instructions. Note: The Cortex-M4 / M7 / M33 / M35P has a silicon option choice of no, Note: The Cortex-M series includes three new 16-bit. Some of the silicon options for the Cortex-M cores are: The Cortex-M0 / M0+ / M1 implement the ARMv6-M architecture,[9] the Cortex-M3 implements the ARMv7-M architecture,[10] the Cortex-M4 / Cortex-M7 implements the ARMv7E-M architecture,[10] the Cortex-M23 / M33 / M35P implement the ARMv8-M architecture,[15] and the Cortex-M55 implements the ARMv8.1-M architecture. The device is 1/10th the size of IBM's previously claimed world-record-sized computer from months back in March 2018, which is smaller than a grain of salt. The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by Arm Holdings. External interface that complies with the AMBA 4 AXI.

The following microcontrollers are based on the Cortex-M0+ core: The following chips have a Cortex-M0+ as a secondary core: The smallest ARM microcontrollers are of the Cortex-M0+ type (as of 2014, smallest at 1.6 mm by 2 mm is Kinetis KL03).[17]. Stack limit boundaries (available only with SAU option). The Cortex-M0 / Cortex-M0+ / Cortex-M1 / Cortex-M23 were designed to create the smallest silicon die, thus having the fewest instructions of the Cortex-M family. In addition to debug features in the existing Cortex-M0, a silicon option can be added to the Cortex-M0+ called the Micro Trace Buffer (MTB) which provides a simple instruction trace buffer. It is called the FPv5 extension. (not available in M0/M0+/M1), Optional Floating-Point Unit (FPU): single-precision only.

[23][24] The instruction and data buses have been enlarged to 64-bit wide over the previous 32-bit buses. Key features of the Cortex-M33 core are:[12][27]. Debug The debug features of the processor implement the Arm debug interface architecture. (M0+/M23). Data endianness: little-endian or BE-8 big-endian. Both are with the original (K&R) v2.1 of Dhrystone, *** Minimum configuration with full ISA support and Interrupt Controller, includes 1 IRQ + NMI, excludes ETM, MPU, FPU, DSP and debug. The Arm Cortex-M7 processor is the most recent and highest performance member of the energy-efficient Cortex-M processor family, and enables partners to build the most sophisticated variety of MCUs and embedded SoCs. On 21 June 2018, the "world's smallest computer'", or computer device was announced – based on the ARM Cortex-M0+ (and including RAM and wireless transmitters and receivers based on photovoltaics) – by University of Michigan researchers at the 2018 Symposia on VLSI Technology and Circuits with the paper "A 0.04mm3 16nW Wireless and Batteryless Sensor System with Integrated Cortex-M0+ Processor and Optical Communication for Cellular Temperature Measurement." Optional Tightly-Coupled Memory (TCM): 0 to 1 MB instruction-TCM, 0 to 1 MB data-TCM, each with optional ECC. New Thumb-1 instructions were added as each legacy ARMv5 / ARMv6 / ARMv6T2 architectures were released. The following microcontrollers are based on the Cortex-M23 core: The Cortex-M33 core was announced in October 2016[27] and based on the newer ARMv8-M architecture that was previously announced in November 2015. Performance Efficiency: 5.01 CoreMark/MHz* and 2.14/3.23 DMIPS/MHz**, * See product, compiler and compiler flags, ** The first result abides by all of the “ground rules” laid out in the Dhrystone documentation, the second permits simultaneous ("multi-file") compilation.

To all licensees, Arm provides an integratable hardware description of the ARM core, as well as complete software development toolset and the right to sell manufactured silicon containing the ARM CPU. Note: Interrupt latency cycle count assumes: 1) stack located in zero-wait state RAM, 2) another interrupt function not currently executing, 3) Security Extension option doesn't exist, because it adds additional cycles. Thumb-2 (some), only BL, DMB, DSB, ISB, MRS, MSR. Cortex-M cores are commonly used as dedicated microcontroller chips, but also are "hidden" inside of SoC chips as power management controllers, I/O controllers, system controllers, touch screen controllers, smart battery controllers, and sensors controllers. Interrupts: 1 to 32 (M0/M0+/M1), 1 to 240 (M3/M4/M7/M23), 1 to 480 (M33/M35P). For example, writing to an alias word will set or clear the corresponding bit in the bit-band region. Cortex-M / M-Profile forum Updated ARMv7-M architecture reference manual for Cortex-M7 ?
