Driving Forces for SOC’s

Set makers face tough competition to reduce material cost

New applications need Low power

Explosive growth of mobile applications Cellular phones, PDA, ...

Small size Mobile applications normally mean portability Reduce number of parts for feature size reduction

High performance Should cope with system-level complexity Multi-media applications

SOC Cooperation

Page 7: SOC Development Trends in Home Applications Seh-Woong Jeong April 25 2002 Media SOC Team System LSI Business Samsung Electronics Co., Ltd.

SOC Requires Tighter Relationship Strategic Relationship between Set Makers & Silicon Vendors Getting

More Important Than Ever Early System Requirement Access : Key to Time-to-Market Working Sample to Design-In : at least 6 months or more

Full Dedication from Both Sides More System Application Engineers in SOC Vendors

10~20 % more than 50% of R&D Work Force Strategic Relationship between Silicon Vendors & IP Vendors

Competitive/Proven IP Portfolio : Bare Minimum for SOC Business You can’t develop everything for yourself !!

Strategic Relationship between Silicon Vendors & Software Algorithm Firmware RTOS/Device Driver/BSP/Application Software Support Hardware Only Makes No Sense to Set-Makers !!

CE-Centric View

Home Server + Home Gateway will be• Set-Top Box or D-TV• DVD-Box (DVD Player/Recorder or iDVD)• Game Console : PS3 from Sony• “If Sony's aspirations succeed, then the Playstation 3 will not be a pure video game

console, but rather measure the amount of milk left in the fridge, record TV programs to hard-disk, automatically download new software, perform Tera-flop operations and a variety of other things. In short, if one can automate, computerize, network or electrify a process, then the PS3 should be able to take on the task.”

Chances are : some form of a convergence box. For example,

• DVD + Set-Top Box with broad-band access capability and mass storage

DVD (Digital Versatile/Video Disc/Disk) An Interesting Article from WP ’02.10.07

“DVD, 할리우드의 최대 수익원으로 부상” '02 년 할리우드 영화의 DVD 판매 및 대여수입은 26 억달러로 극장수입 17 억달러 , 비디오 판매

및 대여수입 16 억달러를 각각 추월하면서 최대 수익원으로 부상 DVD 수입 급증은 무엇보다 DVDP 보급 증가에 기인 VCR 은 9 천만 미국 가구가 보유해 포화 단계인 반면 DVD 는 1 년 전 천 7 백만에서 현재 3

천백만 가구로 급증

DVD 의 경우 VCR 과 달리 소비자들이 타이틀 대여보다 구매를 많이 하는 특성이 있어서 판매 확대가 용이

DVD 보유가구는 올해 평균 260 달러 정도의 16 개 DVD 타이틀을 구매하는 반면 , VCR 보유가구는 평균 5 개의 테이프를 구매

DVD 는 대여료 대비 판매가가 3-5 배에 그치고 , 반영구적인 화질 , 제작과정과 게임 등 다양한 컨텐츠가 있기 때문

디즈니 영화 " 몬스터 " 는 전체 극장수입이 2.6 억 달러였지만 , DVD 를 20 달러에 출시한 첫 주에 1.4 억달러 가치의 7M copies 판매

DVD 는 대량생산이 용이해 제조원가가 적기 때문에 판매 수익도 큼 29.98 달러에 팔린 " 해리포터 " DVD 에서 영화사 몫은 9.98 달러 11 월 1 일 출시될 소니의 " 스파이더 맨 " DVD 는 이미 WalMart 에만 19M copies 납품 등

새로운 판매기록을 세울 전망

Bus Architecture SDRAM Bandwidth Problem

Bandwidth-hungry masters contending over an external SDRAM Single 16-bit SDRAM @ 133MHz used for the cost issue Bandwidth Utilization Serialized bus transaction in single layer AHB

Utilization = data transfer cycles / total clock cycles Multi-layer bus is required.

Low SDRAM bandwidth utilization for random access Access turn around time for each bank : 12 cycles Maximum utilization : about 60% Bank interleaving is required.

Bus Arbitration Scheme Priority Scheduling with Ages

Preventing starvation of low priority masters For each master, latency amount is set by software If latency is more than the amount, priority is incremented. Important feature for CPU/DSP

Read/Write transaction requests have higher priority after read/write transactions, respectively. (in order to localize the same type of accesses)

Priority Rule Interface masters have higher priority. Masters with smaller buffer have higher priority

Usually complex masters need a large buffer. Masters of higher bandwidth have higher priority IO DMA > SD Input > VP > FIU > VD > GA

To display an interlaced video signal on a progressive display

Method Bob

Scan line interpolation/duplication using one field The resulting vertical resolution is limited to the “field”

Weave merging of two consecutive fields The simplest method to implement double resolution Artifacts in regions of movement

3D-IPC(Motion Adaptive IPC) Field merging for still areas of picture and interpolation for areas of

movement Issue: cost function to detect a “movement”
