IP Telephony news wrap-up for Mar 31 – 2006

MIPS has introduced two new families of core processors including the multi-threading 34K line and the 24KE line. Products from both portfolios can be used to develop VoIP products.

The 34K cores are intended for embedded applications. For a single application, the cores would be ideal for multiple voice channels in home applications. they could also be used to merge several single threaded fucntions into a single 34K core such as a host processor running Linux and a DSP running an RTOS in an STB application.

The 34K cores are designed to mask the effect of memory latency by increasing processor utilization. As one thread stalls, additional threads are instantly fed into the pipeline and executed, resulting in a gain in application throughput. Internal benchmarks indicate that the 34Kc core running two threads achieved a 60% speedup over a single-threaded processor with only a 14% increase in die size.

Additionally, the 34K core family delivers real-time responsiveness for embedded applications. Users can allocate dedicated processing bandwidth to real-time tasks resulting in a guaranteed Quality of Service QoS. This mechanism constantly monitors the progress of threads and dynamically takes corrective actions to meet or exceed the real-time requirements.

The 34K cores can run existing 2-way SMP operating systems and applications with minimal changes and can also be used in environments where independent concurrent threads have very different roles.

The cores can be configured with a maximum of two VPEs and five TCs. This dual VPE capability allows the cores to run two independent operating systems concurrently or alternatively a 2-way SMP OS. In addition, up to five TCs can be used to allow a single OS to run up to five processes concurrently.

Members of the 34K family include the 34Kc, 34Kf, 34Kc Pro, and 34Kf Pro.

Specs for the 34Kc cores include processing at 90nn G at a worst case frequency of 500 MHz. The size is 2.1mm2 and the power consumed is .56 mW/ MHz @ 1.0V.

The 34Kf cores include hardware floating support compliant with IEEE 754. The Pro Series cores feature the capability to add proprietary instructions and tightly coupled hardware to the cores via CorExtend.

Cores in this product line have been licensed by iVivity, Mobileye and PMC-Sierra.

Solution providers using this core family include Accelerated Technology, Cadence, CoWare, Denali, Express Logic, First Silicon, Green Hills Software, Magma, Microsoft, Sonics, Synopsys, TimeSys, Virage Logic, and Virtio.

The 24KE core family features converged RISC/DSP functionality, ideal for applications requiring both control and signal processing. With the inclusion of the company’s new DSP ASE, the cores in this product line do not need a separate DSP.

The cores are fully static, fully synthesizable, and require no custom cells or memories. They can be synthesized using best-of-class physical IP from multiple vendors. For example, in a 90nm GT process, using high speed memories from Dolphin Technology and high speed standard cells, the cores can achieve a clock frequency of 850MHz. At 1.46 DMIPS/MHz, this design provides 1240 DMIPS.

The 24KE cores can also be synthesized in a 90nm G process using standard cells and memories such as those from Virage Logic. Using this IP, when optimized for power and area, a complete 24KE processor, including 16K I and D Level 1 caches, occupies 2.0mm2 and consumes 0.43 mW / MHz. Even lower power figures can be achieved by using multi-VT and voltage/frequency scaling.

The 24KE core family is targeted at markets such as set-top boxes, DTVs, DVD recorders, voice switches, IP phones, digital cameras, cellular telephones, printers, modems, residential gateways, and automotive telematics. The cores are also ideal for battery-powered and thermally-constrained devices.

Applications enhanced by the MIPS32 DSP ASE include VoIP processing, narrowband and broadband communications, digital audio, graphics, video, and imaging. Some examples of the speedup achieved by the DSP ASE include a 68% improvement in IDCT processing (used in video compression) and a 106% speedup in IMDCT (used in MP3 decoding). Complex DSP kernel functions such as FIR filters achieve up to a 234% performance boost, while a standard 32×32 DCT with saturation is improved by 315%.

The 24KE core family includes the 24KEc, 24KEf, 24KEc Pro, and 24KEf Pro.

The 24KEc Core, the base core for the product line, includes the MIPS32 instruction set, a MMU, a fast multiple/divide unit, and the MIPS DSP ASE. The @$KEf includes all of the features of the Ec core plus a hardware floating point unit. The pro cores, as with the aforementioned product family, allow designers to add proprietary, user defined instructions and tightly coupled hardware. The instructions integrate with the processor’s normal execution pipeline.
