In response to increased consumer demand for immediate access to their remote music collections and streaming Internet radio service on inexpensive, advanced systems, Texas Instruments has announced its third-generation DA830 and DA828 Aureus digital audio processors. The highly-integrated, dual-core DA8x product line offers the combined features of an ARM-based applications processor and an audio digital signal processor (DSP) core, as well as a wide range of peripherals.
This compilation results in a high-performance, cost-effective solution for consumer products such as network-connected Audio/Video Receivers (AVR), Home Theater in a Box (HTIB) and mini/micro component systems. Thus, designers can enable consumers to have access to endless amounts of music while enjoying the cinema quality sound they are accustomed to in their home theatre system, but at a lower price.
For those designing AVRs, HTIBs and mini/micro component systems, the cost savings is a result of the integration of a 300MHz 64-bit floating/fixed point audio DSP engine with a 300MHz ARM926EJ-S core, an Ethernet MAC, two USB ports, an SD/MMC interface, PWM processors and an LCD controller, which eliminates multiple system components and reduces PCB board space. To ease design, TI provides a networked AVR Software Developer’s Kit (nAVR SDK) with an integrated Performance Audio Framework (PAF) that includes standard, multi-channel decoding and post-processing algorithms required for AVRs, including all HD audio decoders, Dolby TrueHD, Dolby Digital Plus and DTS-HD, integrated into the on-chip ROM. Trendsetting manufacturers can utilize the fully programmable ARM and DSP cores to create differentiated products as well as drive high-end features - such as smart volume, room correction and connectivity - into entry level audio systems.
“We’ve worked with TI’s audio processors for several years and they consistently provide the cutting-edge features and functionality that help us remain innovative in the AVR market,” said Nobuaki Okuda, executive officer, Onkyo Corporation. “With customers becoming more advanced and desiring more sophisticated, modern systems, we must provide end equipment that is second to none. As a leading provider of scalable solutions for the AVR market, TI’s technology gives us this advantage.”
