35、2009(E) ISO/IEC 2009 All rights reserved vii Introduction The main goal of this Technical Report is to facilitate a more widespread use of the MPEG-4 standard. Design methodologies of the EDA industry have evolved from schematics to Hardware Description Languages (HDLs) to address the needs of the v
36、ast number of gates available on a single device. The increased number of gates allowed more elaborate algorithms to be deployed but also required a shift in design paradigm to handle the complexity created. Through HDLs, more complicated systems could be designed faster through the enabling technol
37、ogy of synthesis of the HDL code towards different silicon technologies where trade offs could be explored. Now the EDA industry again faces challenges where HDLs may not provide the level of abstraction needed for system designers to evaluate system level parameters and complexity issues. There hav
38、e been a number of tool investigations under way to address this problem. Profiling tools aid in exposing bottlenecks in an abstract way so that early design decisions can be made. C to gates tools allow a C based simulation environment while also enabling direct synthesis to gates for hardware acce
39、leration. In conclusion, it is the aim of this Technical Report to enable more widespread use of the MPEG-4 standard through reference hardware descriptions and close integration with MPEG-4 Part 7 Optimized Reference Software. Additionally, it is aimed that exposure to such a platform will enable a
40、 more systematic way to investigate the complexity of new codecs and open up the algorithm search space with an order of magnitude more compute cycles.

43、ware description language (HDL) form. Such alternative descriptions to the ones that are reported in ISO/IEC 14496-2, ISO/IEC 14496-5 and ISO/IEC TR 14496-7 correspond to the need of providing the public with conformant standard descriptions that are closer to the starting point of the development o
44、f codec implementations than textual descriptions or pure software descriptions. This part of ISO/IEC 14496 contains conformant descriptions of video tools that have been validated within the recommendation ISO/IEC TR 14496-7. 2 Copyright disclaimer for HDL software modules Each HDL module shall be
