ARM Cortex-M1 Processor
Soft ARM ® Processor Designed for FPGAs
Overview
CoreCortex M1 processor is a general purpose 32-bit microprocessor that offers high performance and small size in FPGAs.For PolarFire and RTG4 Product Families the Cortex-M1 soft CPU is licensed under the terms of ARM Cortex-M1 End User License Agreement (EULA).
To obtain the core please contact Tech Support https://microchipsupport.force.com/s/
CoreCortexM1 processor runs a subset of the Thumb-2 instruction set (ARMv6-M) that includes all base 16-bit Thumb instructions and a few Thumb-2 32-bit instructions (BL, MRS, MSR, ISB, DSB, and DMB). This enables writing very tight and efficient processor code, which is ideal for the limited memory typically found in deeply-embedded applications.
