TMPM370 is a 32-bit RISC microprocessor series with an ARM Cortex-M3 microprocessor core.
- ARM Cortex-M3 microprocessor core
- Improved code efficiency has been realized through the use of Thumb®-2 instruction
- New 16-bit Thumb instructions for improved program flow
- New 32-bit Thumb instructions for improved performance
- New Thumb mixed 16-/32-bit instruction set can produce faster, more efficient code
- Both high performance and low power consumption have been achieved.(High performance)
- 32-bit multiplication (32 × 32 = 32bit) can be executed with one clock
- Division takes between 2 and 12 cycles depending on dividend and devisor[Low power consumption]
