MIPS at the core of advanced smart cards
New from MIPS Technologies, the MIPS32 4KSc smart card core is a high-performance, synthesisable embedded 32bit processor core for ultra-low-power advanced smart card applications.
TSMC delivers hard core processors for MIPS fans
MIPS Technologies has announced the availability of "hard core" versions of its MIPS32 4Kc and 4Km 32bit processor cores.
Supported by a complete suite of software development tools and the MIPS DSP Library, the DSP ASE enables SoC designers to simplify their design environment and lower system cost by eliminating hardwired logic and migrating DSP functionality onto a MIPS-based host processor.
DVD recorders, digital cameras, residential gateways and VoIP phones are examples of the growing list of consumer products that require an increasing amount of signal and media processing horsepower.
And, in the cost-sensitive, high-volume consumer electronics market, eliminating unnecessary hardware and tool chains and reducing royalty payments can result in savings of millions of dollars.

To address these trends, MIPS Technologies is enhancing its industry-standard architecture with DSP functionality to provide a single design environment that leverages a common tool set and knowledge base.
The MIPS DSP ASE offers licensees a programmable solution for DSP applications, allowing adaptation to changing market needs and extending the life of an SoC design.
The new DSP extension comprises a set of new instructions and state in the integer pipeline of MIPS Technologies cores and requires less than 6% additional silicon area to implement in a 24K-class core.
"From low-end printers and digital cameras to highly complex network switches, increasing signal processing requirements are putting pressure on the limited resource pool of DSP programmers", said Will Strauss, President and CEO of Forward Concepts, an Arizona-based market research firm.
"With the MIPS DSP ASE and DSP Library, SoC designers can leverage many popular DSP algorithms and support tools needed to efficiently process media tasks".
"MIPS Technologies continues to add optimized software to its leading synthesizable and hardened core product lines to reduce the SoC design challenges in our target markets", said Russ Bell, Vice President and Marketing at MIPS Technologies.
"The DSP architectural extension is the latest example of our strategy to expand the reach and capability of the MIPS ecosystem".
"The market response has been overwhelmingly positive and reinforces our position as the market and technology leader in embedded design".
The MIPS DSP ASE is fully supported with Gnu-based software development tools.
Features of the MIPS DSP ASE include: 8, 16 and 32bit SIMD instructions; saturating and fractional maths; popular DSP operations, such as MAC, dot-product, absolute and complex-multiply; and key features such as variable bit insert/extract and virtual circular buffers.
Tools, library and operating system support comprise: MIPS Software Toolkit support, including tuned compiler (C front-end), assembler, debugger, instruction-set simulator and performance analysis tools; the MIPS DSP Library, a set of key DSP functions, including DCT, FFT, filters and other popular functions; and Linux support.
The DSP ASE is available for licensing by MIPS32 and MIPS64 ISA customers.
Additionally, this technology will appear in future 32 and 64bit cores developed by MIPS Technologies.
