BA2x 32-bit Processor IP Cores Family

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.

Additional peripherals are available, individually or in a complete BA2x-AHB-PP or BA2x-AXI-PP platform.

BA2 Instruction Set Architecture

Innovative ISA combines RISC and non-RISC techniques:

  • Multiple-length instruction coding: 16, 24, 32 or
    48 bits
  • Powerful flow control & arithmetic 32 GPRs vs. 16 typical
  • DSP & Floating-Point extensions

Extreme code density reduces system-wide energy consumption:

  • Smaller memories & caches
  • More code in caches vs. power-hungry memory
  • Fewer instructions and more sleep

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

Cost-Effective and Royalty-Free

An investment in a BA2x processor core pays for itself many times over by shrinking development time and allowing designers to focus on other competitive differentiators.

CAST’s time-tested licensing offers project-based, royalty-free terms, meaning developers pay a fixed, known amount for each core, regardless of production volume or product lifetime.

We also encourage you to try the processor before you commit, with ready-to-run evaluation systems.
