TMS320VC5509AZAY Nā Mea Hana & Nā Mana Manaʻo - DSP, DSC Paʻa-Point Hōʻailona Hōʻailona 179-NFBGA -40 a 85

Hoʻokumu ʻia ka TMS320VC5509A paʻa paʻa kikohoʻe kikohoʻe (DSP) ma luna o ka TMS320C55x DSP generation CPU processor core. Loaʻa i ka C55x™ DSP architecture ka hana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ma o ka hoʻonui ʻana i ka parallelism a me ka nānā nui ʻana i ka hōʻemi ʻana i ka mana. Kākoʻo ka CPU i kahi kaʻa kaʻa kūloko i haku ʻia me hoʻokahi kaʻa kaʻa papahana, ʻekolu mau pahi heluhelu ʻikepili, ʻelua mau pahi kākau ʻikepili, a me nā kaʻa ʻē aʻe i hoʻolaʻa ʻia no ka hana peripheral a me DMA. Hāʻawi kēia mau kaʻa kaʻa i ka hiki ke hana i ʻekolu heluhelu ʻikepili a kākau ʻelua ʻikepili i ka pōʻai hoʻokahi. Ma ka like, hiki i ka mea hoʻokele DMA ke hana i ʻelua mau hoʻoili ʻikepili i kēlā me kēia pōʻai kūʻokoʻa i ka hana CPU.

Hāʻawi ka C55x CPU i ʻelua ʻāpana multiply-accumulate (MAC), hiki i kēlā me kēia mea ke hoʻonui i ka 17-bit x 17-bit i ka pōʻai hoʻokahi. Kākoʻo ʻia kahi kikowaena helu helu 40-bit/logic (ALU) e kekahi ALU 16-bit hou. Aia ka hoʻohana ʻana i nā ALU ma lalo o ka mana hoʻonohonoho aʻoaʻo, e hāʻawi ana i ka hiki ke koho i ka hana parallel a me ka hoʻohana mana. Mālama ʻia kēia mau kumuwaiwai ma ka Address Unit (AU) a me Data Unit (DU) o ka C55x CPU.

Kākoʻo ka hanauna C55x DSP i kahi ʻōlelo aʻo ākea byte i hoʻonohonoho ʻia no ka hoʻomaikaʻi ʻana i ka nui code. Hoʻokō ka Instruction Unit (IU) i nā kiʻi polokalamu 32-bit mai ka hoʻomanaʻo i loko a i waho a hoʻonohonoho i nā kuhikuhi no ka Unit Program (PU). Hoʻokaʻawale ka Papahana i nā ʻōlelo aʻo, kuhikuhi i nā hana i nā kumuwaiwai AU a me DU, a hoʻokele i ka pipeline pale piha. ʻAʻole hiki i ka wānana lālā ke pale i ka hoʻoheheʻe ʻana o ka pipeline i ka hoʻokō ʻana i nā ʻōlelo aʻo kūlana.

ʻO nā hana hoʻokomo a me nā hana hoʻopuka a me ka 10-bit A/D e hāʻawi i nā pine kūpono no ke kūlana, nā keʻakeʻa, a me ka bit I/O no nā LCD, nā kīʻaha, a me nā pilina media. Hoʻohana ʻia ka interface parallel ma nā ʻano ʻelua, ma ke ʻano he kauā i kahi microcontroller me ka hoʻohana ʻana i ke awa HPI a i ʻole ma ke ʻano he interface media parallel me ka hoʻohana ʻana i ka EMIF asynchronous. Kākoʻo ʻia ka media serial ma o ʻelua MultiMedia Card/Secure Digital (MMC/SD) peripherals a me ʻekolu McBSPs.

Aia ka 5509A peripheral set i kahi hoʻomanaʻo hoʻomanaʻo waho (EMIF) e hāʻawi ana i ke komo ʻole i nā hoʻomanaʻo asynchronous e like me EPROM a me SRAM, a me nā hoʻomanaʻo kiʻekiʻe kiʻekiʻe e like me ka synchronous DRAM. Loaʻa i nā peripheral ʻē aʻe ka Universal Serial Bus (USB), ka uaki manawa maoli, ka manawa kiaʻi, ka I2C multi-master a me ke kauā kauā. ʻEkolu piha-duplex multichannel buffered serial ports (McBSPs) hāʻawi i ka glueless interface i nā ʻano mea hana serial maʻamau o ka ʻoihana, a me ke kamaʻilio multichannel a hiki i ka 128 mau kaha kaʻawale. ʻO ka interface host-port i hoʻonui ʻia (HPI) he 16-bit parallel interface i hoʻohana ʻia no ka hāʻawi ʻana i ke kaʻina hana hoʻokipa i ka 32K bytes o ka hoʻomanaʻo kūloko ma ka 5509A. Hiki ke hoʻonohonoho ʻia ka HPI ma ke ʻano multiplexed a i ʻole multiplexed mode e hāʻawi i ka glueless interface i nā ʻano like ʻole o nā kaʻina hana hoʻokipa. Hāʻawi ka mea hoʻoponopono DMA i ka neʻe ʻana o ka ʻikepili no nā pōʻaiapili kaila kūʻokoʻa ʻeono me ka ʻole o ka hana CPU, e hāʻawi ana i ka DMA throughput a hiki i ʻelua mau huaʻōlelo 16-bit i kēlā me kēia pōʻai. Hoʻokomo pū ʻia nā mea hoʻopaʻa manawa maʻamau ʻelua, a hiki i ʻewalu mau pine I/O (GPIO) i hoʻolaʻa ʻia, a me ka hoʻokumu ʻana o ka uaki paʻa paʻa kikohoʻe (DPLL).

Kākoʻo ʻia ka 5509A e ka ʻoihana lanakila-lanakila eXpressDSP™, Code Composer Studio™ Integrated Development Environment (IDE), DSP/BIOS™, Texas Instruments 'algorithm standard, a me ka ʻoihana ʻoihana ʻekolu ʻaoʻao. Hōʻike ka Code Composer Studio IDE i nā mea hana code generation me kahi C Compiler a me Visual Linker, simulator, RTDX™, XDS510™ emulation device drivers, a me nā modula loiloi. Kākoʻo ʻia ka 5509A e ka C55x DSP Library e loaʻa ana ma mua o 50 mau polokalamu kernels kumu (FIR filters, IIR filters, FFTs, a me nā hana makemakika like ʻole) a me nā hale waihona puke kākoʻo chip a me ka papa.

Ua hoʻokumu ʻia ka TMS320C55x DSP core me kahi hoʻolālā hāmama e hiki ai i ka hoʻohui ʻana i nā hāmeʻa kikoʻī noiʻi e hoʻoikaika i ka hana ma nā algorithm kikoʻī. ʻO ka hoʻonui ʻia ʻana o ka lako ma ka 5509A e hoʻopaʻa i ke koena kūpono o ka hana paʻa me ka hiki ke hoʻolālā ʻia, ʻoiai e loaʻa ana ka hoʻohana haʻahaʻa haʻahaʻa, a me ke kumukūʻai maʻamau i paʻakikī ke loaʻa i ka mākeke wikiō-processor. Hāʻawi nā hoʻonui i ka 5509A e hāʻawi i ka hana codec wikiō kūʻokoʻa me ka hapa nui o kāna bandwidth i loaʻa no ka hana ʻana i nā hana hou e like me ka hoʻololi ʻana o ka waihoʻoluʻu, nā hana hoʻohana-interface, palekana, TCP/IP, ka ʻike leo, a me ka hoʻololi ʻana i ka kikokikona i ka ʻōlelo. ʻO ka hopena, hiki i kahi 5509A DSP ke hoʻohana i ka nui o nā noi wikiō kikohoʻe me ka hoʻoponopono headroom e hoʻomaha. No ka 'ike hou aku, e 'ike i ka TMS320C55x Hardware Extensions for Image/Video Applications Programmer's Reference (helu palapala SPRU098). No ka ʻike hou aku e pili ana i ka hoʻohana ʻana i ka DSP Image Processing Library, e ʻike i ka TMS320C55x Image/Video Processing Library Programmer's Reference (helu palapala SPRU037).
