  5. MIPS/RISC Features - 指令集的限制 • 指令长度必须都是32位， 不可能把一个32位常数放进单个指令 • 指令操作必须适合流水线 • 三操作数的指令 • 32个通用寄存器 • 寄存器零 • 没有条件码 - 寻址和访存 • 访问内存只能通过简单的寄存器加载和存储 • 只有一种数据寻址方式 • 字节地址指令 - 符号扩展和零扩展 • load/store必须对齐 • 跳转指令 - 没有的特性 • 没有字节或半字数据的运算 • 没有对堆栈的特殊支持 • 最少的子程序支持 • 最少的中断处理 • 最少的异常处理

  6. Pipeline from programmer point of view • 分支延迟

  11. ngPlatform Requirement View to FxP • Networking (Big area) • O&M (Big area) • HAS (Big area) • Data access (Big area) • Others(TBD) • Notes: • One architect member will be as main contact of each big area. ~2 engineers(not architect team member) can be involved in area reseach. • Reference of FxP Domain:

  12. ngPlatform Function Domain View • DC • CM • TT(Includes signalling)

  13. ngPlatform Requirement View to eSW & HW platform • LMP • Octeon node • Switch

  14. ngPlatform E2E Requirement View Application N GPLATF O R M IPALight FxP HW Platform eSW

  15. ngPlatform E2E Requirement View • Telecom • Solution(for example: co-siting) • O&M • Traffic Transport • Resource Management • Others ? • Note: E2E Requirement View is maintained.

  16. ngPlatform System Domain View at ngPlatform • C&P • Deployment ? • Availability • Startup • Testability ? • Upgrade(commission) • Operability • Traffic Engineering
