cw001102 - 120 mhz low power synthesized arm966e-s ? core overview the cw001102 processor core is a low power implementation of the popular arm966e-s ? , synthesized onto lsi logic?s g12l 0.18 micron low leakage process technology. the arm966e-s, which is based on the five stage pipeline arm9e-s ? harvard architecture processor, also contains a complete memory subsystem of tightly coupled instruction and data rams, an embedded trace macrocell (etm) interface, and an amba ? (advanced microprocessor bus architecture) ahb (advanced high performance bus) interface unit. this high level of integration helps ease the task of integrating the core into your system on chip (soc) design. tight coupling of the ram allows for high speed operation and predictable memory timing. this makes the core an ideal choice for real time systems needing timing critical execution. the instruction and data ram sizes are user configurable up to 512 k bytes. the ahb interface includes a write buffer capable of burst transfers and split transactions. the etm interface, when used with the optional etm core, provides extensive real-time trace capabilities. features and benefits 0.7 mw/mhz power dissipation t j =115 o c, v dd =1.8 v, slow process g12l 0.18 micron, 1.8 v low leakage process 120 mhz operating frequency arm966e-s industry standard architecture configurable memory subsystem for maximum flexibility synthesized core for optimal timing accuracy and asic compatible design flow complete amba subsystem reference design available extensive portfolio of amba peripherals regional arm coreware design support etm (embedded trace macrocell) ram control arm9e-s system controller instruction ram data ram write buffer and ahb interface tm arm966e-s tm block diagram the communications company tm
120mhz synthesized arm96 6e-s core the arm966e-s supports the armv5te instruction set including all of the arm9e family dsp instruction extensions. the core supports for both the arm ? 32-bit and thumb ? 16-bit instruction sets, making it upwardly code-compatible with both the arm7tdmi ? and arm9tdmi ? families. the ability to switch on the fly between arm and thumb instruction sets allows the user to trade between high performance and code density. the built in amba bus interface of the arm966e-s core is an ideal standard bus for building a complete cpu subsystem design. lsi logic offers both an amba subsystem reference design, and a library of popular amba cpu peripherals for use by customers on soc designs. customers can also incorporate their own amba based blocks onto this widely used industry standard bus. the arm966e-s is supported by a wide array of software development tools available from arm limited as well as third party vendors. the core is implemented in lsi logic?s g12l low leakage 0.18 micron (drawn) process, giving a maximum speed of 120 mhz (worst case commercial). power consumption for the core is just 0.7 mw/mhz, making this core ideal for a variety of portable applications. the cw001102 core is synthesized onto the g12l soc cell library and is provided complete with highly accurate timing models that fully support static timing analysis (sta) through the core. this can be a significant benefit for achieving timing closure on high performance designs. the core is fully compatible with lsi logic?s entire flexstream ? soc asic design flow making it straightforward to integrate into complex customer designs. the cw001102 comes complete with built in full scan chains for good testability, and is provided with a comprehensive set of deliverables including design files, sta and atpg scripts, and detailed integration guidelines. to further assist customers with their designs, lsi logic provides specialized arm coreware ? integration support through our team of regionally based field coreware engineers. for more information please call: lsi logic corporation north american headquarters milpitas, ca tel: 800 574 4286 lsi logic europe ltd. european headquarters united kingdom tel: 44 1344 426544 fax: 44 1344 481039 lsi logic kk headquarters tokyo, japan tel: 81 3 5463 7165 fax: 81 3 5463 7820 lsi logic web site www.lsilogic.com lsi logic logo design, flexstream, coreware and gigablaze are registered trademarks, speedblazer logo design and speedblazer are trademarks of lsi logic corporation. arm and thumb are registered trademarks of arm limited. arm966e-s, arm9e-s, amba, arm7tdmi, and arm9tdmi are trademarks of arm limited. all other brand names and product names may be trademarks of their respective companies. lsi logic corporation reserves the right to make changes to any products and services herein at any time with out notice. lsi logic does not assume any responsibility or liability arising out of the application or use of any product or service described herein, except as expressly agreed to in writing by lsi logic; nor the purchase, lease, or use of a product or service from lsi logic convey a license under any patent, copyright, trademark rights, or any other of the intellectual property rights of lsi logic or of third parties. copyright ? 2001 by lsi logic corporation. all rights reserved. order no. c20043 601.1k.sr.ik - printed in usa the communications company tm
