These configurable, highly efficient hardware platforms reduce development effort, the risk of costly silicon re-spins and, ultimately, time-to-market for embedded processor applications. It uses industry standard system buses, offering designers the ability to add their own hardware blocks or connect the DSP to other systems present on chip, making integrating CEVA cores a very straightforward, efficient proposition. Both platforms support critical low power design requirements through CEVA's smart Power Management Unit (PMU) technology, which includes automatic sleep/wake of each resource and matrix separately according to transaction type, source, destination, initiator and duration.
"Our customers compete in some of the most dynamic and fastest moving markets and need every advantage possible to reduce time, risk and development complexity. These enhanced platforms build on our track record of expertise in wireless and multimedia, and provide an extremely effective way to leverage the capabilities of our family of DSP cores into complete systems," said Eran Briman, vice president, corporate marketing at CEVA. "More than 90% of our CEVA-X DSP core customers also license a complementary CEVA subsystem, illustrating the critical value-add that these platforms bring to developing complex processor-based solutions."
The two platforms -- which have evolved through numerous customer engagements in targeted application areas -- feature architecture enhancements that can significantly lower die size and power consumption, without compromising on performance. They are geared for the most complex and highly integrated SoCs, and feature a complete AHB matrix, DMA, TDM ports, power management, external master and slave ports, complete lineup of DSP-oriented peripherals and interface to L2 memories.
Compared to previous generation platforms from CEVA, the new platforms offers designers the following advantages:
-- 10% higher speed
-- 20% smaller die size
-- 20% lower leakage power and 10% lower dynamic power
-- 50% fewer clock-tree cells, ensuring higher production yield
-- 5% decrease in MHz requirements for video codecs such as H.264
Application-optimized Platforms
The CEVA XS1100A platform is optimized for wireless baseband and general purpose DSP solutions and tightly couples the CPU and DSP, which is required for real time baseband processing. It includes the following main features:
-- Smart Power Management Unit (PMU) for dynamic control of power
consumption
-- Complete set of hardware peripherals extendible through an APB bridge
-- Host controller connectivity through AHB compliant bridges
-- Two-level memory architecture enabling shared memory between CEVA DSP
and ARM cores, reducing system complexity, die size and power
consumption
-- Code replacement unit enabling on-the-fly firmware program bypasses
The CEVA XS1200A platform, aimed at multimedia and other DSP-intensive applications, enables a de-coupling of the CPU and DSP to support multiple independent clock systems. It integrates additional features that enhance the system processing power for applications such as digital multimedia devices and includes:
-- A 16-channel advanced DMA with 3D transfer capabilities, allowing the
DSP to handle most of the data traffic autonomously
-- An interface to third-party accelerators that can be used for
DSP-intensive applications
-- Up to 4 TDM ports for use as the interface to audio and voice data
