Ibisobanuro

OMAP-L138 C6000 DSP + ARM itunganya ni imbaraga zingirakamaro zikoreshwa zishingiye kuri ARM926EJ-S hamwe na C674x DSP.Iyi processor itanga imbaraga nke cyane ugereranije nabandi bagize TMS320C6000 ™ platform ya DSPs.Igikoresho gifasha ibikoresho-byumwimerere (OEMs) nabakora-bishushanyo-byumwimerere (ODMs) kuzana byihuse kubikoresho byisoko hamwe na sisitemu ikora ikomeye, interineti ikungahaye cyane, hamwe n’imikorere ihanitse binyuze mu buryo bworoshye bwo guhuza ibisubizo byuzuye, bivanze bitunganijwe.Ubwubatsi bubiri bwibikoresho bitanga inyungu zombi za DSP no kugabanya amabwiriza yashyizweho ya mudasobwa (RISC), ikubiyemo imikorere ya TMS320C674x DSP ikora cyane hamwe na ARM926EJ-S.ARM926EJ-S ni intungamubiri ya 32-bit ya RISC ikora 32-bit cyangwa 16-bit amabwiriza kandi igatunganya amakuru 32-, 16-, cyangwa 8-bit.Intangiriro ikoresha imiyoboro kugirango ibice byose bitunganyirizwa hamwe na sisitemu yo kwibuka ikore ubudahwema.Intangiriro ya ARM9 ifite coprocessor 15 (CP15), module yo gukingira, hamwe namakuru hamwe na progaramu yo gucunga porogaramu yibuka (MMUs) hamwe nameza yo kureba-kuruhande.Intangiriro ya ARM9 ifite amabwiriza atandukanye ya 16-KB na cashe ya 16-KB.Cashe zombi ninzira-4 zifatanije na indangagaciro yibintu (VIVT).Intangiriro ya ARM9 ifite 8KB ya RAM (Imbonerahamwe ya Vector) na 64KB ya ROM.Igikoresho DSP yibanze ikoresha ibyiciro 2-cache-ishingiye kububiko.Urwego rwa 1 cache ya progaramu (L1P) ni 32- KB ya mape cache itaziguye, naho urwego rwa 1 cache data (L1D) ni 32-KB 2-nzira, gushiraho-gufatanya.Urwego rwa 2 cache ya progaramu (L2P) igizwe na 256-KB yibibanza bisangiwe hagati ya progaramu n'umwanya wa data.L2 yibuka irashobora gushyirwaho nkububiko bwa mape, cache, cyangwa guhuza byombi.Nubwo DSP L2 ishobora kugerwaho na ARM9 hamwe nabandi bashitsi muri sisitemu, iyindi 128KB ya RAM isanganywe ububiko iraboneka kugirango ikoreshwe nabandi bashitsi bitagize ingaruka kumikorere ya DSP.
