INkxaso yoMyalelo woMyalelo oNgcotshiweyo weNdawo edadayo
Kwi-v13.1, i-Qsys yongeza ukhetho lokukhetha inqaku elitsha lesiseko somyalelo wecandelo, i-Floating Point Hardware 2. Ukuthatha i-advantagInkxaso yesoftware ye-Floating Point Hardware 2 imiyalelo, ibandakanya i-altera_nios_custom_instr_floating_point_2.h, enyanzelisa i-GCC ukuba ibize imisebenzi yezibalo entsha (kunokuba i-GCC eyakhelwe-ngaphakathi imisebenzi yezibalo). I-Altera icebisa ukuba uqokelele i-newlib ngeyona ndlela isebenzayo.
Phawula: Sukusebenzisa i -mcustom -fpu-cfg yelayini yomyalelo wokhetho lweGCC. Olu khetho aluyixhasi i-Floating Point Hardware 2 imiyalelo. Izixhobo zokwakha zesoftware ye-Nios II (SBT) yongeza imiyalelo yomntu ngamnye -mcustom ukwenzafile ukuxhasa iFloating Point Hardware 2 imiyalelo yesiko.
Inkxaso ye-ECC
Ukuqala kwi-v13.1, umhleli weparameter yeProsesa ye-Nios II ikuvumela ukuba wenze ukhuseleko lwe-ECC kwii-RAM kwi-core processor kunye ne-cache yomyalelo. Ngokungagqibekanga, i-ECC ayenziwanga ukuba isetyenziselwe ukusetwa ngokutsha. Ke ngoko, isoftware kufuneka ivule ukhuseleko lwe-ECC. Isoftware inokufaka iimpazamo ze-ECC kwiibits zedatha ye-RAM ukuxhasa uvavanyo lwe-ECC yokuphatha ngaphandle kunye nebhasi yesiganeko. I-Nios II Hardware Abstraction Layer (HAL) iyandiswa ukuxhasa ukuqaliswa kwe-ECC kunye nokusingatha ngaphandle.
I-Universal Boot Copier
Kwi-v13.1, umkhupheli we-Nios II we-boot uphuculwe ukuxhasa iintlobo ezininzi zezixhobo ezikhanyayo. Umkhupheli ophuculweyo we-boot ubizwa ngokuba yi-universal boot copier. I-Nios II ikhuphela ikopi yokubini yesicelo ukusuka kwisixhobo somenyezi ukuya kwinkumbulo eguquguqukayo. Imemori edanyazayo ibekwe ngomfanekiso weFPGA kweyona dilesi yenkumbulo isezantsi, ilandelwa yi Nios II yesicelo semifanekiso yokubini. Kukhupho lwangaphambili lwemveliso, ubungakanani bomfanekiso weFPGA bulungiswe kusapho lwesixhobo ngasinye. Nangona kunjalo, kwizixhobo ezikwi-Cyclone V, Stratix V, kunye neentsapho zakwa-Arria V, ubungakanani bomfanekiso buyohluka ngokuxhomekeke kwezi zinto zilandelayo:
- Uhlobo oludanyazayo: I-Quad-output (EPCQ) okanye i-single-output (EPCS) Isixhobo soqwalaselo esomeleziweyo
- Umthamo isixhobo Flash: 128 okanye 256 Mbits
- Uxinzelelo
- Ujongano lothotho lweperipheral (SPI) uqwalaselo: ×1 okanye ×4
- Ubume besixhobo: enye okanye i-cascade
Kunzima kumshicileli wesiqalo ukuchonga indibaniselwano yangoku ukuze ikwazi ukusebenzisa ubungakanani bomfanekiso obufanelekileyo, kwaye nayiphi na ialgorithm inokusilela ukuxhasa uqwalaselo lwexesha elizayo. Ukusombulula le ngxaki, iheader yongezwa kumfanekiso weFPGA ukucacisa ubungakanani bomfanekiso. Ngokusebenzisa ubungakanani bomfanekiso ukusuka kwiheda, umkhupheli wendalo yonke wesiqalo unokusebenza ngalo naluphi na uqwalaselo lweflash kwizixhobo zangoku okanye ezizayo. Isixhobo se-sof2flash sihlaziywa ukuxhasa umkhupheli we-universal boot. Olu tshintsho alunampembelelo kwisakhono se-FPGA ibhloko yokulawula ukucwangcisa ngokuzenzekelayo umfanekiso weFPGA kumandla-on.
Imiba eyaziwayo kunye ne-Errata
Olu luhlu lulandelayo lunemiba eyaziwayo kunye neempazamo, ukuba zikhona:
- Kukho umahluko omncinci kwindlela yokuziphatha ye-cache ye-Nios II Gen2 enokuthi ichaphazele abaphuhlisi abakhetha ukunyusela indlela yokuziphatha ye-cache engekho eqhelekileyo ye-classic processors kwizicelo zabo.
