All Silicon IP


Implements a 32-bit low-power RISC processor that delivers better performance than most processors of its size. Designed for deeply-embedded systems or as an auxiliary processor in larger systems, it is an especially effective choice for wireless communication, analog peripherals management, or other mixed-signal functions in energy-and cost-sensitive applications. This royalty-free 32-bit processor core is binary-compatible with other members of the silicon-proven BA2x processor family. Its BA2 instruction set is relatively simple and extremely compact, offering system area and energy savings benefits. Programing is facilitated with the included C/C++ tool chain, Eclipse IDE, architectural simulator, and ported C libraries, RTOSs, and OSs.
