"We chose the MIPS architecture because it met all of our high-end telecom requirements and was the perfect processor for running our BL2000 PONmaker software for ONT and PON," explain Eli Weitz, vice president of VLSI for BroadLight. "In addition, we were extremely pleased throughout the entire design, verification, and layout processes."
By incorporating the 4KEc core, BroadLight says it was able to significantly reduce development cost and speed time to market with its end-to-end GPON platform, which will be delivered to its first tier customers by December 2005.
MIPS says its MIPS32 4KE family of processor cores are ideal for the development of high-performance, low power-consuming integrated chipsets for customer-end applications. The 4KE Pro cores feature the company's CorExtend capability, which enables designers to add user-defined instructions. The company says the synthesizable 32-bit cores offer performance of 1.5 Dhrystone MIPS/MHz.
Other features of the processor cores include MIPS16e code compression, 64KB instruction and 64KB writeback data caching, a coprocessor 2 (COP2) interface, extensive clock gating, BIST, scan, and Enhanced JTAG (EJTAG) debug capability with trace and fast download features, and support for all major operating systems and compiler tool chains, as well as hundreds of third-party development tools.
Broadlight says its BL2000 is an application-optimized, integrated platform for designing ITU-T G.984 GPON and ITU-T G.983 BPON compliant ONT equipment. The platform includes the company's PONmaker software, as well as OLT MAC, OLT, and ONT optical transceivers.
