ARM7TDMI Structure

At the heart of an application-specific system is an embedded microcontroller core such as the ARM7TDMI. This offers 32-bit performance at 16-bit system costs with an industry-leading MIPS/Watt.

• 32-bit RISC processor core.

• Two instruction sets:
  - ARM high-performance 32-bit instruction set.
  - Thumb high-code-density 16-bit instruction set.

• Very low power consumption:
  - Industry-leader in MIPS/Watt.

• Von Neumann load/store architecture:
  - Single 32-bit data bus for instructions and data.

• 3-stage pipeline architecture:
  - Fetch, decode and execute stages.

• 8-, 16- and 32-bits data types:
  - Support for big and little endian.

• Single-cycle 32x8 hardware multiplier:
  - Multiplication is accelerated when upper bytes are all zero or one.

• On-chip JTAG Debug and In Circuit Emulation.

• A wide range of compatible peripheral cores.
