Dual-core Cortex A9 embedded MPU for multimedia

The SPEAr1340 device is a system-on-chip belonging to the SPEAr®(Structured Processor Enhanced Architecture) family of embedded microprocessors. The product is suitable for consumer and professional applications where an advanced human machine interface (HMI) combined with high performance are required, such as low-cost tablets, thin clients, media phones and industrial/printer smart panels.

The device is hardware-compliant to the support of both real-time (RTOS) and high-level (HLOS) operating systems, such as Android, Linux and Windows Embedded Compact 7.

The architecture of SPEAr1340 is based on several internal components, communicating through a multilayer interconnection matrix (BUSMATRIX). This switching structure enables different data flows to be carried out concurrently, improving the overall platform efficiency.

In particular, high-performance master agents are directly interconnected with the DDR memory controller in order to reduce access latency. The overall memory bandwidth assigned to each master port can be programmed and optimized through an internal weighted round-robin (WRR) arbitration scheme.
