Microprocessor from STMicroelectronics Enables Compelling User
Interfaces and Multimedia in Computing and Industrial Applications
Integration of two
ARM Cortex-A9 cores and hardware graphics/video processing delivers
delivers outstanding performance
May 4, 2011 - STMicroelectronics today introduced
its new embedded microprocessor with advanced multimedia capabilities.
The latest addition to ST’s dual-core ARM Cortex-A9
microprocessor family, the SPEAr1340 targets a broad range
of smart connected devices, from high-resolution video-conferencing
to intelligent displays and web-connected devices.
ST’s SPEAr1340 integrates a powerful ARM Mali 200 graphics
processing unit for advanced 2D and 3D acceleration in user
interfaces, navigation systems, browsing, and gaming. The
new device also embeds a hardware video encoder and a decoder
supporting major compression standards (including H.264, AVS
and VP8), with video resolution up to 1080p and 30 frames
per second. The SPEAr1340 can also handle multiple concurrent
video flows (4 camera inputs available) in multimedia-intensive
applications like surveillance video cameras.
The hardware implementation of graphics and video capabilities
in the SPEAr1340 results in state-of-the art multimedia performance
at ultra-low power consumption, while maintaining the two
Cortex-A9 cores available for performing concurrent tasks
as requested by the users. With its multiple interfaces, including
I2S and S/PDIF, the SPEAr1340 also provides excellent audio
capabilities, handling up to 7.1 surround-sound configurations
in both input and output paths.
In security, the SPEAr1340 integrates a multi-standard cryptographic
engine and One Time Programmable (OTP) registers for unique
identification and external flash memory anti-tamper protection.
“The SPEAr1340 represents the leading edge of the embedded
microprocessor market,” said Loris Valenti, General
Manager of STMicroelectronics’ Computer Systems Division.
“The unique combination of formidable processing power,
high-level features, peripheral integration and advanced multimedia
capabilities targets applications from entry-level web-connected
devices to video-conferencing and security systems.”
Manufactured in ST’s low-power 55nm HCMOS (high-speed
CMOS) process technology, the new microprocessor benefits
from the state-of-the-art SPEAr1300 architecture, which combines
the unrivalled low-power and multi-processing capabilities
of two ARM Cortex-A9 cores with innovative Network-on-Chip
The dual ARM Cortex-A9 processors support both fully symmetric
and asymmetric operations, at speeds of 600MHz/core (industrial
worst-case conditions) for 3000 DMIPS equivalent. Network-on-Chip
is a flexible communications architecture providing ‘Quality
of Service’ (QoS) for the whole system as it enables
multiple different traffic profiles while maximizing data
throughput in the most performance- and power-efficient way.
Other features of the SPEAr1340 include
- 1x Giga/Fast Ethernet ports (for external GMII/RGMII/MII
- 1x PCIe/SATA Gen2 links (with embedded PHY)
- 2x USB 2.0 host ports with integrated PHYs
- 1x USB2.0 OTG port with integrated PHY
- I2S, UARTs, SPI, I2C ports
- HD Display controller with Touch screen and Overlay windows
- Memory Card controller supporting multiple standards
- 6x6 keyboard controller
- 4x Camera inputs
- 4 -bit Parallel-port Video Input
- 2x Consumer Electronic Control (CEC) ports
- Secure Boot and Key Storage capabilities
- Power-saving features
Samples of the SPEAr1340 are now available only to lead
customers for evaluation and prototyping. Software support
is provided through the STLinux distribution and further distributions
and support environments will be added in the future.
