TMS320VC5509AZAY Ndị na-ahụ maka mgbama dijitalụ & ndị njikwa – DSP, DSC Ihe Nrụpụta Mgbama Dijitalụ 179-NFBGA -40 ruo 85

Ihe nrụpụta akara ngosi dijitalụ TMS320VC5509A nke edobere isi (DSP) dabere na TMS320C55x DSP ọgbọ CPU isi. Ihe owuwu C55x ™ DSP na-arụ ọrụ dị elu yana ike dị ala site na mmụba myirịta na mkpokọta mkpokọta na mbelata mgbasa ike. CPU na-akwado usoro ụgbọ ala dị n'ime nke nwere otu ụgbọ ala mmemme, ụgbọ ala na-agụ data atọ, bọs na-ede data abụọ, na ụgbọ ala ndị ọzọ raara nye na mpaghara na ọrụ DMA. Ụgbọ ala ndị a na-enye ike ịrụ ihe ruru agụ data atọ yana data abụọ na-ede n'otu okirikiri. N'otu aka ahụ, onye na-ahụ maka DMA nwere ike ịrụ ọrụ nnyefe data ruru abụọ n'otu okirikiri na-adabereghị na ọrụ CPU.

C55x CPU na-enye nkeji ọnụọgụ abụọ (MAC), nke ọ bụla nwere ike ịba ụba 17-bit x 17-bit n'otu okirikiri. Otu 16-bit ALU na-akwado akụkụ mgbakọ na mwepụ etiti 40-bit. Ojiji nke ALU dị n'okpuru njikwa nhazi ntuziaka, na-enye ikike ịkwalite ọrụ ndị yiri ya na oriri ike. A na-ejikwa akụrụngwa ndị a na ngalaba Adreesị (AU) na Ngalaba Data (DU) nke C55x CPU.

Ọgbọ C55x DSP na-akwado ntụziaka obosara byte agbanwe agbanwe maka njupụta koodu ka mma. Ngalaba Ntuziaka (IU) na-eme mmemme 32-bit sitere na ebe nchekwa dị n'ime ma ọ bụ mpụga yana ntuziaka kwụ n'ahịrị maka Ngalaba Mmemme (PU). Ngalaba mmemme na-akọwapụta ntuziaka, na-eduzi ọrụ na akụrụngwa AU na DU, ma na-ejikwa pipeline echedoro nke ọma. Ikike ịkọ amụma na-ezere ịgbanye pipeline na mmezu ntuziaka ọnọdụ.

Ọrụ ntinye na mmepụta ebumnuche izugbe yana 10-bit A/D na-enye ntụtụ zuru oke maka ọkwa, nkwụsịtụ na ntakịrị I/O maka LCDs, ahụigodo, na oghere mgbasa ozi. Ihe nleba anya na-arụ ọrụ n'ụdị abụọ, ma ọ bụ ohu nke microcontroller na-eji ọdụ ụgbọ mmiri HPI ma ọ bụ dị ka ihe ntanetị mgbasa ozi na-eji EMIF asynchronous. A na-akwado usoro mgbasa ozi site na kaadị MultiMedia/Secure Digital (MMC/SD) peripheral na McBSP atọ.

Ntọala 5509A na-agụnye oghere ebe nchekwa mpụga (EMIF) nke na-enye ohere enweghị mmasị na ncheta asynchronous dị ka EPROM na SRAM, yana ihe ncheta dị elu, nnukwu njupụta dị ka DRAM synchronous. Mgbakwunye agbakwunyere gụnyere Universal Serial Bus (USB), ezigbo elekere, ngụ oge nche, I2C multi-master na interface ohu. Ọdụ ụgbọ mmiri nwere ọtụtụ chanel atọ zuru ezu (McBSPs) na-enye interface enweghị gluu na ngwaọrụ dị iche iche ọkọlọtọ ụlọ ọrụ, yana nkwurịta okwu multichannel nwere ihe ruru ọwa 128 nwere ike iche. The enhanced host-port interface (HPI) bụ 16-bit yiri interface eji na-enye onye nhazi ohere ịnweta 32K bytes nke ebe nchekwa dị n'ime na 5509A. Enwere ike ịhazi HPI n'ụdị multiplexed ma ọ bụ na-abụghị multiplexed iji nye interface enweghị gluu na ọtụtụ ụdị nhazi nnabata. Onye na-ahụ maka DMA na-enye mmegharị data maka ọnọdụ ọwa isii nọọrọ onwe ya na-enweghị enyemaka CPU, na-enye ntinye DMA ihe ruru okwu 16-bit abụọ kwa okirikiri. Agụnyere ngụ oge izugbe abụọ, ihe ruru ntụtụ I/O (GPIO) asatọ raara onwe ya nye, yana ọgbọ elekere elekere dijitalụ (DPLL).
