TMS320VC5509A ƙayyadaddun madaidaicin siginar siginar dijital (DSP) ya dogara ne akan TMS320C55x DSP ƙarni na CPU core.Gine-ginen C55x ™ DSP yana samun babban aiki da ƙaramin ƙarfi ta hanyar haɓaka daidaitattun daidaito da jimlar mayar da hankali kan raguwar ɓarnawar wutar lantarki.CPU tana goyan bayan tsarin bas na ciki wanda ya ƙunshi bas ɗin shirin guda ɗaya, bas ɗin karanta bayanai guda uku, bas ɗin rubuta bayanai guda biyu, da ƙarin bas ɗin da aka keɓe don aiki na gefe da na DMA.Waɗannan motocin bas ɗin suna ba da damar yin karatun bayanai har uku da rubuta bayanai guda biyu a zagaye ɗaya.A layi daya, mai kula da DMA zai iya aiwatar da har zuwa canja wurin bayanai guda biyu a kowane zagaye mai zaman kansa daga ayyukan CPU.

C55x CPU yana ba da raka'o'in tarawa biyu (MAC), kowannensu yana iya ninka 17-bit x 17-bit a cikin zagaye ɗaya.Naúrar lissafi/hankali (ALU) na tsakiya 40-bit yana samun goyan bayan ƙarin 16-bit ALU.Amfani da ALUs yana ƙarƙashin ikon saitin umarni, yana ba da ikon haɓaka aiki na layi ɗaya da amfani da wuta.Ana sarrafa waɗannan albarkatun a cikin Adireshin Adireshi (AU) da Data Unit (DU) na C55x CPU.

Ƙarnin C55x DSP yana goyan bayan ƙayyadaddun koyarwar faɗin byte da aka saita don ingantacciyar ƙimar lamba.Rukunin Umarni (IU) yana aiwatar da ɗimbin shirye-shiryen 32-bit daga ƙwaƙwalwar ajiya na ciki ko na waje da kuma jerin umarni na Unit Shirin (PU).Sashin Shirin yana yanke umarnin umarni, yana jagorantar ayyuka zuwa albarkatun AU da DU, kuma yana sarrafa bututun mai cikakken kariya.Ƙarfin tsinkayar reshe yana guje wa zubar da bututun mai a kan aiwatar da umarnin sharadi.

Ayyukan shigarwa na gaba ɗaya da fitarwa da 10-bit A/D suna ba da isassun fil don matsayi, katsewa, da bit I/O don LCDs, maɓallan madannai, da mu'amalar kafofin watsa labarai.Madaidaicin mahaɗin yana aiki ta hanyoyi biyu, ko dai a matsayin bawa ga microcontroller ta amfani da tashar jiragen ruwa na HPI ko azaman hanyar sadarwa mai kama da layi ta amfani da EMIF asynchronous.Ana goyan bayan Serial kafofin watsa labarai ta hanyar MultiMedia Card/Secure Digital (MMC/SD) gefe guda biyu da McBSP uku.

Saitin na gefe na 5509A ya haɗa da ƙirar ƙwaƙwalwar waje (EMIF) wanda ke ba da damar ganuwa zuwa abubuwan da ba a haɗa su ba kamar EPROM da SRAM, haka kuma zuwa ga babban sauri, ƙwaƙwalwar ƙima kamar DRAM na aiki tare.Ƙarin abubuwan da ke kewaye sun haɗa da Universal Serial Bus (USB), agogon ainihin lokaci, mai ƙidayar lokaci, I2C mashahurai da yawa da kuma haɗin bayi.Manyan tashoshin jiragen ruwa masu dumbin yawa guda uku (McBSPs) suna ba da keɓance mara igiyar ruwa zuwa nau'ikan na'urorin siriyal na masana'antu iri-iri, da sadarwar multichannel tare da har zuwa tashoshi 128 da aka kunna daban.Ingantacciyar hanyar sadarwa ta tashar tashar jiragen ruwa (HPI) ita ce keɓantacciyar hanyar sadarwa ta 16-bit da ake amfani da ita don samar da hanyar sarrafa mai watsa shiri zuwa 32K bytes na ƙwaƙwalwar ciki akan 5509A.Ana iya daidaita HPI a ko dai yanayin da ba a haɗa shi ba ko kuma mara ɗimbin yawa don samar da keɓancewar mannewa zuwa nau'ikan masu sarrafawa iri-iri.Mai sarrafa DMA yana ba da motsin bayanai don mahallin tashoshi masu zaman kansu guda shida ba tare da sa hannun CPU ba, yana samar da kayan aikin DMA har zuwa kalmomi 16-bit guda biyu a kowane zagaye.Masu ƙidayar maƙasudi guda biyu, har zuwa takwas keɓaɓɓun maƙasudin I/O (GPIO) na gabaɗaya, da kuma tsara agogon kulle lokaci-lokaci (DPLL) an haɗa su.

5509A yana samun goyan bayan eXpressDSP ™ masana'antar ta lashe lambar yabo, Code Composer Studio™ Integrated Development Environment (IDE), DSP/BIOS™, Texas Instruments 'algorithm mizanin, da kuma babbar cibiyar sadarwa ta ɓangare na uku na masana'antu.Code Composer Studio IDE yana fasalta kayan aikin ƙirƙira lambar gami da C Compiler da Visual Linker, na'urar kwaikwayo, RTDX™, Direbobin na'urar kwaikwayo na XDS510, da ƙirar ƙima.Hakanan 5509A yana samun goyan bayan ɗakin karatu na C55x DSP wanda ke fasalta fiye da 50 tushen kernels na software (masu tace FIR, matattarar IIR, FFTs, da ayyuka daban-daban na lissafi) da kuma guntu da ɗakunan karatu na allo.

An ƙirƙiri ainihin TMS320C55x DSP tare da buɗaɗɗen gine-gine wanda ke ba da damar ƙari na takamaiman kayan aiki don haɓaka aiki akan takamaiman algorithms.Abubuwan haɓaka kayan aiki akan 5509A suna buga cikakkiyar ma'auni na ƙayyadaddun aikin aiki tare da sassaucin shirye-shirye, yayin da ake samun ƙarancin ƙarfi, da tsadar da al'ada ke da wahalar samu a cikin kasuwar sarrafa bidiyo.Ƙwararren yana ba da damar 5509A don sadar da aikin codec na musamman na bidiyo tare da fiye da rabin bandwidth ɗin sa don yin ƙarin ayyuka kamar canjin sararin samaniya, ayyukan mai amfani, tsaro, TCP/IP, muryar murya, da kuma fassarar rubutu-zuwa-magana.Sakamakon haka, 5509A DSP guda ɗaya na iya ƙarfafa mafi yawan aikace-aikacen bidiyo na dijital mai ɗaukar hoto tare da sarrafa ɗakin kai don keɓancewa.Don ƙarin bayani, duba TMS320C55x Hardware Extensions for Hoto/Video Applications Reference (lambar adabi SPRU098).Don ƙarin bayani kan amfani da Laburaren sarrafa Hoto na DSP, duba TMS320C55x Hoto/Video Mai Gudanar da Laburaren Magana (lambar adabi SPRU037).
