“…The SH4 [41], the latest SH series microprocessor for multimedia applications from Sharp, has architectural enhancement-based on the unique FP vector instructions that are more effective than the conventional SIMD architecture for 3-D graphics processing. Several other SIMD-based processors were proposed by [42], [43].…”

Multimedia processing is becoming increasingly important with a wide variety of applications ranging from multimedia cell phones to high-definition interactive television. Media processing involves the capture, storage, manipulation and transmission of multimedia objects such as text, handwritten data, audio objects, still images, 2-D/3-D graphics, animation, and full-motion video. A number of implementation strategies have been proposed for processing multimedia data. These approaches can be broadly classified based on the evolution of processing architectures and the functionality of the processors. In order to provide media processing solutions to different consumer markets, designers have combined some of the classical features from both the functional and evolution-based classifications resulting in many hybrid solutions. We propose a categorization of existing microprocessors based on a combination of both architectural and functional flavors with examples of each approach from the latest multimedia processing families. The varying processing requirements in multimedia computing for reconfigurable multimedia processing.

“…With programmable cores, several different algorithms can be executed on the same hardware, and the functionality of a specific system can be easily upgraded by a change in software. Multimedia processing schemes in general can be partitioned in stream oriented, block oriented, DSP oriented, and control oriented functions [1,2]. Each of these tasks requires either a lot of computational power and special functions to efficiently perform an operation.…”

Systems-on-chips provide single-chip solutions in many embedded applications to meet the applications size and power requirements. Media processing such as real-time compression and decompression of video signal is now expected to be the driving force in the evolution of media processor. The MediaSoC322xA consists of two fully programmable processor cores and integrates digital video encoder. The programmable cores toward a particular class of algorithms: the MediaDSP3200 for RISC/DSP oriented functions and multimedia processing, and the RISC3200 for bit stream processing and control function. Dedicated interface units for DRAM, SDRAM, Flash, SRAM, on screen display and the digital video encoder are connected via a 32-bit system bus with the processor cores. The MediaSoC322xA is fabricated in a 0.18um 6LM standard-cell SMIC CMOS technology, occupies about 20mm 2 , and operates at 180MHz. The MeidaSoC322xA are used to audio/video decoder for embedded multimedia application.

“…For this purpose, recent multimedia DSP processors such as Texas Instruments TMS320C62xx [l] and Philips TriMedia [2] feature highly parallel architecture and optimizing compilers. On the other hand, there are some embedded RISC microprocessors designed for consumer multimedia applications, such as NEC V830WAV [3] and Mitsubishi D30V [4]. Today's high-end general-purpose processors are also known for their extended multimedia instruction sets, for example, Intel MMX [SI, HP MAX-2 [6], and Sun VIS [7].…”

As the complexity of multimedia applications increases, the need for efficient and compiler-friendly processor architectures also grows. In this paper, a new multimedia processor architecture is proposed. This processor has a 2-issue VLIW architecture with 64-bit SIMD arithmetic functional units to exploit the instructionlevel and subword data parallelism found in multimedia applications. Moreover, densely encoded instructions supporting memory operands, DSP-like addressing modes, and SIMD capability boost the performance while keeping the code size and hardware cost small. To maximally utilize this architecture, a software environment including a code converter, a VLIW compiler system, and a compiled simulator has also been developed. The processor core has been synthesized for LSI logic 0.25 pm library, which results in the total gate count of 102K. In spite of the relatively smaller issue rate, the proposed processor shows a comparable or higher performance in terms of both the cycle count and the code size when compared to the 8-issue TMS320C62xx, for DSP benchmark kernels and an H.263 video encoder. 0-7803-5650-0/99/$10.00 0 1999 IEEE
