1/3 data brief march 2005 STI5301 high-performance set-top box decoder rev. 1 description the new mpeg-2 decoder from st provides a step-change in performance for pay tv set-top boxes and digital video recorders. delivering 1.33 gops of processing power through an st230 vliw cpu running at 333 mhz, st has ensured that manufacturers? investment in new products is protected as the STI5301 can easily accommodate today?s interactive software, and provides a platform that can support the even more demanding applications of the future. both linux and os21 operating systems are supported, and an mmu provides support for virtual memory management. the STI5301?s power comes from the vliw architecture of the st230 cpu. this allows four instructions to be executed at each cpu cycle, dramatically increasing performance. by maintaining pin compatibility with the sti5100, manufacturers can make use of the STI5301 with minimal hardware redesign. package (27 x 27 pbga 336 package) figure 1.
