RK2710
RK2710 is integrated system-on-chip manufactured by Rockchip.
Overview
1.1 Overview
The RK2710 is an integrated system-on-chip with Dual Core architecture, which will focus on portable DAB, DVB-T solution with multimedia player. The Dual-Core architecture integrated ARM7EJC and DSP micro processor and by co-operating of those two CPUs, RK27xx can get high performance on Low-Power platform.
The RK2710 solution is base on RK27xx PMP solution, also add DAB demodulator architecture and DVB-T decoder.
