ʻO ka LCMXO2-2000HC-4TG144C kaapuni hui hou a me ke kumu

wehewehe pōkole:

ʻO ka ʻohana MachXO2 o ka mana haʻahaʻa haʻahaʻa, hikiwawe, non-volatile PLDs he ʻeono mau mea me nā densities mai 256 a 6864 Look-Up Tables (LUTs).Ma waho aʻe o ka LUT-based, haʻahaʻa haʻahaʻa programmable logic e pili ana kēia mau mea i ka Embedded Block RAM (EBR), Distributed RAM, User Flash Memory (UFM), Phase Locked Loops (PLLs), pre engineered source synchronous I/O support, advanced configuration kākoʻo pū me ka mana pālua-boota a me nā mana paʻakikī o nā hana maʻamau e like me SPI controller, I2C hooponopono a me ka manawa/counter.ʻAe kēia mau hiʻohiʻona e hoʻohana ʻia kēia mau mea hana ma ke kumu kūʻai haʻahaʻa, nā mea kūʻai kiʻekiʻe a me nā noi ʻōnaehana.

Hoʻolauna

Field programmable gate array, ʻo ia ka huahana o ka hoʻomohala hou ʻana ma ke kumu o nā polokalamu programmable e like me PAL, GAL, CPLD a pēlā aku.ʻIke ʻia ʻo ia ma ke ʻano he kaapuni semi-custom ma ke kahua o ka noi-specific integrated circuits (ASICs), ʻaʻole ia e hoʻoponopono wale i nā hemahema o nā kaapuni maʻamau, akā lanakila pū nō hoʻi i nā hemahema o ka helu palena o nā kaʻa kaʻa ʻīpuka polokalamu polokalamu.

Kumu Hana

Hoʻohana ka FPGA i kahi manaʻo hou o ka logic cell array LCA (Logic Cell Array), kahi ʻekolu ʻāpana: configurable logic module CLB, output input module IOB (Input Output Block) a me ka pilina kūloko (Interconnect).ʻO nā hiʻohiʻona kumu o nā FPGA:
1) Ke hoʻohana nei i ka FPGA no ka hoʻolālā ʻana i nā kaapuni ASIC, ʻaʻole pono nā mea hoʻohana e hana i nā chips e kiʻi i kahi chip kūpono.
2) Hiki ke hoʻohana ʻia ka FPGA ma ke ʻano he pilot specimen o nā kaapuni ASIC i hoʻonohonoho piha ʻia a semi-hoʻopilikino paha.
3) Loaʻa i ka FPGA ka waiwai o nā flip-flops a me nā pine I/O i loko.
4) ʻO ka FPGA kekahi o nā mea hana me ka pōkole hoʻolālā pōkole, ke kumu kūʻai haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa loa i ka ASIC circuit.
5) Hoʻohana ka FPGA i ke kaʻina CHMOS kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa, a hiki ke kūpono me nā pae CMOS a me TTL.
Hiki ke ʻōlelo ʻia ʻo FPGA chips kekahi o nā koho maikaʻi loa no nā ʻōnaehana liʻiliʻi liʻiliʻi e hoʻomaikaʻi i ka hoʻohui ʻana o ka ʻōnaehana a me ka hilinaʻi.

Hoʻolālā ʻia ka FPGA e kahi papahana i mālama ʻia i ka RAM on-chip e hoʻonohonoho i kona kūlana hana, no laila pono e hoʻolālā ʻia ka RAM on-chip i ka wā e hana ai.Hiki i nā mea hoʻohana ke hoʻohana i nā ʻano papahana like ʻole e like me nā ʻano hoʻonohonoho like ʻole.

Ke hoʻohana ʻia ka mana, heluhelu ka chip FPGA i ka ʻikepili mai ka EPROM i ka RAM programming on-chip, a ma hope o ka pau ʻana o ka hoʻonohonoho ʻana, komo ka FPGA i ke kūlana hana.Ma hope o ka nalo ʻana o ka mana, hoʻi ka FPGA i nā pepa keʻokeʻo, a nalowale ka pilina pili kūloko, no laila hiki ke hoʻohana pinepine ʻia ka FPGA.ʻAʻole pono ka polokalamu FPGA i kahi polokalamu FPGA i hoʻolaʻa ʻia, he polokalamu EPROM a me PROM wale nō.Ke pono ʻoe e hoʻololi i ka hana FPGA, e hoʻololi wale i ka EPROM.Ma kēia ala, hiki i ka FPGA like, nā ʻikepili papahana like ʻole, ke hana i nā hana kaapuni like ʻole.No laila, maʻalahi ka hoʻohana ʻana i nā FPGA.

Nā ʻano hoʻonohonoho

Loaʻa i ka FPGA nā ʻano hoʻonohonoho like ʻole: ʻo ke ʻano nui like he FPGA me kahi EPROM;Hiki ke kākoʻo ke ʻano kumu-kauā i hoʻokahi PIECE PROM hoʻolālā i nā FPGA he nui;Hiki ke hoʻolālā ʻia ke ʻano Serial me ka serial PROM FPGA;Hiki i ke ʻano pilipili ke hoʻohana ʻia ka FPGA ma ke ʻano he peripheral o kahi microprocessor, i hoʻolālā ʻia e ka microprocessor.

ʻO nā pilikia e like me ka hoʻokō ʻana i ka pani manawa wikiwiki, ka hoʻemi ʻana i ka hoʻohana ʻana i ka mana a me ke kumukūʻai, ka hoʻoponopono ʻana i ka uaki, a me ka hōʻemi ʻana i ka paʻakikī o nā hoʻolālā FPGA a me PCB i mau pilikia nui no nā ʻenekini hoʻolālā ʻōnaehana e hoʻohana ana i nā FPGA.I kēia lā, i ka neʻe ʻana o nā FPGA i kahi kiʻekiʻe kiʻekiʻe, ʻoi aku ka nui, ka hoʻohana haʻahaʻa o ka mana, a me ka hoʻohui ʻana o IP, ua pōmaikaʻi nā ʻenekini hoʻolālā ʻōnaehana mai kēia mau hana kiʻekiʻe ʻoiai ke kū nei i nā hoʻolālā hoʻolālā hou ma muli o nā pae ʻike ʻole o ka hana a me ka hiki o nā FPGA.
