San Jose--Sept. 22, 1997--Toshiba America Electronic Components Inc. (TAEC; San Jose) announced the availability of the Toshiba Mpact 2/6000 media processor. Toshiba is the first Mpact semiconductor partner to offer this new version of the Mpact 2 media processor. Mpact 2 is the silicon portion of the Mpact solution, which includes a single high-bandwidth, highly parallel media processor, Mpact mediaware software modules, and the PC's existing X86 or X86 MMX CPU.
Designated the TC80310SB, Toshiba's 125 MHz Mpact 2 chip is a powerful multimedia engine with the capability to process 6,000 millions of operations per second (MOPS). It is ideal for PC motherboards and add-in card solutions for PCI-based bus systems as well as Intel's Advanced Graphics Port (AGP) bus, which offers increased bandwidth. Mpact 2 offers twice the overall processing capacity of the original Mpact/3000 media processor, and several times more performance for 3D graphics.
Mpact 2 will be able to accommodate a range of multimedia functions including MPEG1 and MPEG2 video, high-end wave table audio, high-performance 2D and 3D graphics acceleration, audio, fax/modem, telephony, and videoconferencing. These multimedia features are enabled by Mpact mediaware software from Chromatic Research Inc.
Optimized for 3D speed and performance, Mpact 2 includes a 35-stage 3D pipeline. The 3D pipeline is a powerful 3D rendering engine that complements the programmable 3D operation already occurring in other sections of the processor's architecture for higher level of detail and faster frame rates. A dedicated texture cache provides the 3D rendering engine with ultra-fast access to frequently used textures. Mpact 2 also offers a 500 million floating point operations per second (MFLOPs) set-up engine to define polygon points and color spaces. Trilinear filtering smooths and prevents blockiness on textures. Specular highlighting shows reflection from a light source on an object's interface. It is fully compatible with Microsoft Direct3D Application Programming Interface (API).
The Mpact 2 solution is also a powerful 2D graphics accelerator for both Windows and DOS applications. It enables fast, flicker-free, high-resolution color modes including 1600 by 1200 by 18bit @ 85 MHz and 1280 by 1024 by 24bit @ 85 MHz.
In addition to its advanced graphics capabilities, Mpact 2 enables a complete DVD playback solution, which builds on the success of the first-generation Mpact DVD solution. Mpact 2 provides hardware-accelerated DVD without the need for additional hardware.
Unlike specialized graphics chips, Mpact 2 enables full DVD functionality. Mpact 2 DVD features include full-screen, 30 frame-per-second (fps) MPEG2 decoding as well as full 5.1-channel Dolby Digital AC-3 audio decoding. SRS TruSurround audio technology offers virtual six-speaker sound from two standard stereo speakers. AVsync technology provides real-time audio and video synchronization. Mpact mediaware enables a number of DVD acceleration features to ensure fully-compliant DVD functionality. These include IEEE 1180 Inverse Discrete Cosine Transform (IDCT) to ensure crisp picture quality with minimal noise, exact motion compensation for motion free of artifacts, full sub-picture decoding, full DVD navigation implementation, and an approved Content Scrambling System for decryption of copy protected content.
In addition, Mpact 2 DVD features Chromabright and Chromadjust post video processing features which allow the user to digitally adjust the DVD picture quality on-the-fly.
Mpact 2 offers the flexibility to adapt to evolving standards and emerging technologies through Mediaware software upgrades. It is designed to work with Microsoft Windows and will be compatible with next-generation Windows operating systems including Windows NT.
The Mpact media processor was architected by Chromatic Research Inc. and is co-developed and sold by TAEC. Toshiba's Mpact 2 is based on its advanced 0.35 (m drawn CMOS process technology. The design of the Mpact media processor combines elements of supercomputing and digital signal processing (DSP) technologies. It includes a very high bandwidth, parallel architecture, very long instruction word (VLIW) and single-instruction/multiple data (SIMD) execution, and vector processing to achieve the speed and throughput necessary to perform several multimedia functions concurrently, in real time. The Mpact 2 also makes use of two channels of base or concurrent Rambus DRAM (RDRAM) for its multimedia memory. With the use of the concurrent RDRAM, the memory bandwidth of a Mpact 2-based multimedia subsystem will be about 1.3 Gbytes per second. RDRAM acts as the central store for all multimedia data and mediaware modules and provides the necessary bandwidth needed for a single-chip, low pin count solution.
Toshiba offers a complete family of Mpact silicon to meet a range of needs. These include the Mpact/3600 and the Mpact R/3600 media processors. Both the Mpact/3600 and Mpact R/3600 media processors offer performance up to 3600 MOPS, and support 600 MHz RDRAM for increased memory bandwidth. The MpactR/3600 media processor adds an integrated RAMDAC for added performance and integration.
Samples of Toshiba's Mpact 2 will be available in Sept. 1997 with full production slated for October 1997. Toshiba expects the bill-of-materials cost for a complete 2D/3D plus DVD board to be well under $100, including Mediaware.
