N. Osawa · 2002
2B is an operating system based on BTRON2 specification which supports multimedia and distributed processing. 2B follows the basic design philosophy of BTRON2 and has a hierarchical structure. The hierarchy of 2B can be decomposed into three major layers: inner kernel, outer kernel, and shell. Each layer in the hierarchy consists of modules. The design policy of 2B, the internal structure of layers, and the implementation of 2B for TRON specification CPU are described.>
