CompactRISC Core Architecture Overview

The CompactRISC architecture was created from the ground up as a scalable architecture, covering the 16-bit embedded processor domain, while providing the best of RISC and CISC architectures. It established itself in applications that require significant embedded performance, but cannot afford the size and cost overhead of full 32-bit RISC implementations. It employs industry-standard AHB bus system, providing full 32-bit data memory space and supporting on-chip debug and trace capabilities.

 

Main CompactRISC Architecture Benefits

  • Minimal Die Size: Provides space for on-chip application specific peripherals and memory
  • Small Code Size: Avoids typical code expansion of RISC processors
  • High Performance: Delivers sufficient performance to meet most embedded application needs
  • Reduces Power: Suitable for portable applications
  • Design Flexibility: Uses a modular internal bus for interface to a variety of peripherals
  • Proven Design: Used by National Semiconductor and other silicon providers over a range of processes
  • Fully Synthesizable: Available through IPextreme, Inc. partner for Licensing.
  • Established / Proven Development Tools
