MPEG-4 Audiovisual Codec LSI Preliminary TC35273 TOSHIBA Confidential 2000-4-27 1/23 Version 0.90 TOSHIBA MPEG-4 Audiovisual LSI TC35273 Tentative Technical Data Sheet MPEG-4 Audiovisual LSI Features
 TC35273 is an MPEG-4 audiovisual codec LSI which supports 3GPP 3G-324M video telephony system. MPEG-4 video codec with QCIF (176x144 pixel) at 15 frames/s, AMR (Adaptive Multi Rate) speech codec, and ITU-T H.223 are executed concurrently at around 70MHz clock rate.
 Three signal processing units, an MPEG-4 video codec, a speech codec / audio decoder, and a multiplex / demultiplex unit, are integrated on a single chip.
 A 12-Mbit embedded DRAM is integrated as a shared memory for the three signal processing units. The embedded DRAM helps to reduce power consumption without performance degradation.
 Each signal processing unit consists of a 16-bit RISC processor and dedicated hardware accelerators so as to bring programmability, high performance and low power consumption.
 Firmware programs for the RISCs are downloaded into the embedded DRAM before starting operation. Various applications are performed by choosing an appropriate firmware.
 General host interface are adopted in order to support various host CPU.
 2.5x to 6x of PLL is integrated on the chip for easy system integration. • TOSHIBA continually is working to improve the quality and the reliability of its products.
