32-bit RISC ProcessorIP CoreBA22-RTBA22 32-bit Real-Time Embedded Processor

Implements a 32-bit processor for deeply embedded applications that use off-chip instruction and data memories and that may need to run a real-time operating system (RTOS). Part of the royalty-free BA22 family, this processor core is extremely competitive in terms of high performance and low power consumption, and has best-in-class code density (yielding very small program size).

The core has Instruction and Data Caches, optional dedicated buses for tightly coupled on-chip Instruction and Data memories, and an AMBA® AHB™ or Wishbone system bus interface. It includes up to 32 general purpose registers (GPRs), a tick-timer (TTimer), a programmable interrupt controller (PIC), an advanced power management unit (PMU), and an optional debug unit (DBGU). Additional microcontroller peripherals may be ordered for pre-integration and delivery with the core, individually or in a complete platform. IP Integration Services are also available to help integrate any BA22 processor configuration with memory controllers, image compression, or other CAST IP cores.

The processor’s BA2 instruction set is relatively simple and extremely compact. Programing is facilitated with the included C/C++ tool chain, Eclipse IDE, architectural simulator, and ported C libraries.

The BA22-RT synthesizes to less than 20k gates, can be clocked with more than 450MHz in a 65nm technology and can provide as many as 1.69 DMIPS/MHz. The core is delivered, with a complete software development environment under Eclipse IDE, and its users get access to already ported real time operating systems (eCOS and uClinux).

The BA22 family of processors has been designed for easy reuse and integration, has been rigorously verified, and is production proven. Contact CAST Sales for details.

BA22-RT reference designs have been evaluated in a variety of technologies. See representative implementation results (in a new pop-up window):
