The ARM7TDMI core is a member of the ARM family of general-purpose 32-bit microprocessors. The ARM family offers high performance for very low power consumption, and small size.

The ARM architecture is based on Reduced Instruction Set Computer (RISC) principles. The RISC instruction set, and related decode mechanism are much simpler than those of Complex Instruction Set Computer (CISC) designs. This simplicity gives:

• a high instruction throughput
• an excellent real-time interrupt response
• a small, cost-effective, processor macrocell.
