32-bit Basic Application Processor
The BA22-AP is a 32-bit processor for demanding embedded applications that use off-chip instruction and data memories and that may need to run a real-time operating system (RTOS) or a full operating system such as Linux or Android. 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.
The core has Instruction and Data Memory Management Units (MMUs) and Caches, optional dedicated buses for tightly coupled on-chip Instruction and Data memories, and an AMBA® AHB™, AXI-4™ or Wishbone system bus interface. Its base version includes 32 general-purpose registers (GPRs), a tick-timer (TTimer), a programmable interrupt controller (PIC), an advanced power management unit (PMU), and optionally a debug unit (DBGU). The core’s processing capabilities can be enhanced further with the optional hardware Multiply-Accumulate (MAC), IEEE 754 compliant floating-point, and DSP instructions acceleration units. Its interrupt response time can also be optimized with the addition of a Vectored Interrupt controller (VIC).
The BA22-AP supports the variable instruction length BA2 instruction set, benefits from its extreme code density, and is binary compatible with other members of the BA2x processor family. Programing is facilitated with the included C/C++ tool chain, Eclipse IDE, architectural simulator, and ported C libraries. Advanced debugging capabilities and off-the-shelf development boards can further ease software development.
In a typical 28 nm technology, the BA22-AP synthesizes to 38,000 sq. um (or 55k gates, excluding Cache and MMU RAMs) and can be clocked at up to 1000 MHz. Performance is rated at 2.93 Coremarks/MHz.
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.
Part of the royalty-free BA2x family, the BA22-AP processor core has been designed for easy reuse and integration, has been rigorously verified, and is production proven.
