Based on ADSP-BF533 processor’s H.264 decoder
Friday, September 19th, 2008 at 10:03 | No commentsCategories: DSPShort Content: Abstract: The H.264 standard has compared to other video frequency code standard better compression performance, but the computation order of complexity is high, has limited the H.264 standard application. The Blackfin processor is the low power loss which, the high performance fixed-point DSP chip ADI Corporation promotes, has the extremely high performance-to-price ratio, is ideal platform which H.264 standard DSP realizes. In the article discusses on the Blackfin processor realizes the H.264 real-time decoder's method through many kinds of optimization ... -
TigerSHARC structure ADSP-TSl01 and application
Sunday, August 3rd, 2008 at 09:26 | No commentsCategories: DSPShort Content: Introduction ADSP-TSl01 is AD Corporation new generation TigerSHARC structure digital signal processor, has the multi-instruction class multi-data stream (MIMD) structure; Two computing element, each unit including arithmetic logic unit (ALU), shift register (shift), multiplier (mult), register group (register files). The ADSP-TSl01 performance has the remarkable enhancement compared to ADSP21160, and is compatible with it, causes to promote by the ADSP21160 development product is fast, is simple and direct. ADSP-TSl01 is 64 processors, works under 250 MHz clocks, may carry ... -
The ADSP-218X IDMA connection from lifts the design
Saturday, August 2nd, 2008 at 02:53 | No commentsCategories: DSPTags: ADSPShort Content: Abstract: Introduced that ADSP-218X series DSP the chip the IDMA connection from lifts the design and the application. The hardware aspect introduces ADSP-218X the IDMA connection characteristic as well as it and main engine's connection mode; The software aspect introduced how the DSP procedure and the mainframe program code does unify, and downloads the procedure by the main engine through the IDMA connection and ADSP-218X. This method may simplify the system design, reduces the cost. Key word: DSP ... -
ADSP series processor in network multimedia applications
Monday, July 14th, 2008 at 04:28 | No commentsCategories: DSPTags: ADSPShort Content: Abstract: Introduced that ADI Blackfin the series ADSP processor, the double MAC processor construction enables it simultaneously to have the DSP performance and the MCU function, can move the embedded operating system; Simultaneously introduced that in each kind of network multimedia application domains, like the IP set-top box, the network video frequency monitoring, aspect and so on visible VoIP telephone designs, explained how using ADSP processor BF533 and the BF561 construction superiority, simultaneously moves the operating system and carries ...
