32-bit BA2X Processors

Royalty-free, code-dense, low-power MPUs

These BA2x Family processor cores are silicon-proven, royalty-free, easy to program, and technically competitive with traditional 32-bit processor choices.

Their BA2™ instruction set architecture yields extremely dense code, reducing memory and cache sizes, enabling fewer operations and more sleep, and cutting system-level energy consumption.

Various preconfigured versions bundle features and peripherals to target deeply embedded systems through application processors running Android or Linux.

All include the BeyondStudio™ IDE for quick programming, and reference designs, evaluation systems, and integration services are available.

  • BA20: Ultra-low-power, efficient 32-bit processor with PipelineZero, for IoT with high code density.
  • BA21: Low-power, 32-bit processor for deeply embedded systems, featuring two-stage pipeline and advanced power management.
  • BA22-DE: Compact, configurable 32-bit processor with Harvard architecture for embedded applications, offering high clock frequencies.
  • BA22-CE: Cache-enabled 32-bit processor for deeply embedded use, with low power consumption and high performance.
  • BA22-AP: High-performance 32-bit processor for systems requiring off-chip memory, supports Linux/Android.
  • BA25: High-performance 32-bit application processor with seven-stage pipeline, optimized for Linux and Android.
  • Talos-BA2X: Evaluation kit for BA2X cores, including hardware, IDE, and example applications for comprehensive testing.

The BA2 ISA was developed to better exploit state-of-the-art compilers and deliver extreme code-density. Key features of the ISA are:

  • Variable length instruction encoding
    • 16-bit, 24-bit, 32-bit and 48-bit instructions
    • Compiler chooses smallest suitable encoding 
    • Denser code than fixed-length ISAs
  • 32 GPRs mean for less load/store
    • Load/store ~25% of code for typical programs on RISC CPUs
  • Single 24-bit function epilogue instruction, for restoring GPR values from the stack
  • Rich set of arithmetic (including saturated), conditional branch and conditional move instructions
  • DSP & Floating-Point extensions

Extreme code density reduces system-wide energy consumption, smaller code usually translates to: 

  • Smaller memories (non-volatile Flash/OTP and Shadow SRAMs)
  • Less cache misses, and so less access to larger, power-hungry memories
  • Fewer instructions to complete a specific task and longer sleep times

All BA2x processors are supported with development tools including a GCC/Eclipse IDE, libraries, architectural simulator, and reference design/eval system boards.
