ARM® Cortex®-M3 core
ARM flagship Cortex-M series processor
The ARM® Cortex®-M3 processor delivers efficiency and flexibility for responsive and power-sensitive applications. The EFM32TM Giant Gecko, Leopard Gecko, Gecko, and TIny Gecko series leverage the Cortex-M3's low power and high performance features combined with Silicon Labs' unique low-power peripherals to create an exceptional low-power embedded System platform.
First, low power consumption
32-bit Cortex-M3 designed for low-power operation
High power efficiency with the Thumb®-2 instruction set
Small core package supporting integrated power mode
Second, high performance
Cortex-M3 operation rate is 1.25 DMIPS/MHz
Independent data and instruction bus
High code density and performance with the Thumb-2 instruction set
Excellent per-instruction clock cycle ratio
Nested Vectored Interrupt Controller (NVIC), excellent completion of interrupt handling
Advanced math function
Thumb-2 Instruction Set Architecture (ISA)
The Cortex-M3 supports 16 and 32-bit instructions in the Thumb-2 instruction set. The two can be mixed without adding complexity or reducing the performance of the Cortex-M3. The hardware divide instruction and many multiply instructions provide high data throughput for EFM32 users.
Third, based on the Harvard architecture of the three-stage pipelined kernel
The ARM Cortex-M3 three-stage pipeline includes instruction fetch, instruction decode, and instruction execution. The Cortex-M3 also has a separate instruction and data bus. The Harvard architecture reduces the common barriers to data and instruction sharing buses.
Fourth, fast maintenance of critical tasks and interruptions
The EFM32 Cortex-M3 can enter active mode from low power mode in 2 μs and achieve 1.25 DMIPS/MHz operation rate in the Dhrystone 2.1 benchmark. The NVIC is a complete component of the Cortex-M3 processor, ensuring excellent interrupt handling. Up to 240 physical interrupts with a priority of 1-256 can be configured, and non-maskable interrupts further improve interrupt handling. For embedded systems, this enhanced decision mechanism makes it possible to handle critical tasks within a known number of cycles.
Fifth, reduce the 32-bit package
The Cortex-M3's smaller package reduces system cost. The 32-bit high performance shortens the active period of the application and the CPU processes the data during the active period. After the active period is shortened, the applied battery life is significantly extended, and the EFM32 can operate in an efficient low-energy mode for most of the time.
