Yakavandudzwa Inoyangarara Nzvimbo Tsika Yekuraira Tsigiro
Mu v13.1, Qsys inowedzera sarudzo yekusarudza itsva inoyangarara poindi yetsika yekuraira seti chikamu, Inoyangarara Point Hardware 2. Kutora advantage yerutsigiro rwesoftware yeFloating Point Hardware 2 mirayiridzo, inosanganisira altera_nios_custom_instr_floating_point_2.h, iyo inomanikidza GCC kudaidza newlib math function (panzvimbo peGCC yakavakirwa-mukati masvomhu mabasa). Altera inokurudzira kuti udzokorore newlib nekuita kwakanyanya.
Cherechedza: Usashandise iyo -mcustom -fpu-cfg yekuraira-mutsara sarudzo yeGCC. Iyi sarudzo haitsigire iyo Floating Point Hardware 2 mirairo. Iyo Nios II software yekuvaka maturusi (SBT) wedzera munhu -mcustom mirairo pakugadzirafile kutsigira Floating Point Hardware 2 tsika mirairo.
ECC Tsigiro
Kutanga muv13.1, iyo Nios II processor parameter mupepeti inoita kuti iwe ugone kugonesa ECC kuchengetedzwa kwema RAM mu processor core uye cache yekuraira. Nekumisikidza, ECC haigone kugoneswa pakugadzirisa. Naizvozvo, software inofanirwa kugonesa ECC kuchengetedzwa. Software inogonawo kubaya zvikanganiso zveECC muRAM data bits kutsigira kuyedzwa kweECC kunze kwemubati uye bhazi rechiitiko. Iyo Nios II Hardware Abstraction Layer (HAL) inowedzerwa kutsigira ECC kutanga uye kusarudzika kubata.
Universal Boot Copier
Mu v13.1, Nios II boot copier inovandudzwa kuti itsigire mamwe marudzi emagetsi emagetsi. Iyo yakakwidziridzwa boot copier inonzi universal boot copier. Iyo Nios II bhutsu yekukopa inokopa mabhinari ekushandisa kubva kumagetsi emagetsi kuenda kune inoshanduka ndangariro. Iyo flash memory yakaiswa pamwe neFPGA mufananidzo pane yakaderera memory kero, ichiteverwa neNios II application binary mifananidzo. Mukuburitswa kwechigadzirwa chakapfuura, saizi yemufananidzo weFPGA yakagadziriswa mhuri yega yega mudziyo. Nekudaro, kune zvishandiso zviri muCyclone V, Stratix V, uye mhuri dzeArria V, saizi yemufananidzo inosiyana zvichienderana neanotevera akasiyana:
- Flash type: Quad-output (EPCQ) kana single-output (EPCS) Yakanatsiridzwa Programmable Configuration mudziyo
- Flash mudziyo kugona: 128 kana 256 Mbits
- Compression
- Serial peripheral interface (SPI) kugadzirisa: ×1 kana ×4
- Chimiro chemudziyo: imwechete kana cascaded
Zvakaoma kuti mukopi webhutsu aone kusanganiswa kwazvino kuitira kuti ishandise saizi yemufananidzo yakakodzera, uye chero algorithm inogona kutadza kutsigira zvirongwa zveramangwana. Kugadzirisa dambudziko iri, musoro unowedzerwa kumufananidzo weFPGA kutsanangura saizi yemufananidzo. Nekushandisa saizi yemufananidzo kubva kumusoro, iyo universal boot copier inogona kushanda nechero flash configuration mune zvazvino kana ramangwana zvishandiso. Iyo sof2flash utility inogadziridzwa kutsigira universal boot copier. Shanduko iyi haina kukanganisa pakugona kweFPGA control block kuti igadzirise otomatiki mufananidzo weFPGA pamagetsi.
Zvinozivikanwa Nyaya uye Errata
Rondedzero inotevera ine nyaya dzinozivikanwa uye errata, kana iripo:
- Pane mutsauko mudiki muNios II Gen2 processor cache maitiro anogona kukanganisa vanogadzira vanosarudza kukwidziridza iyo isiri-yakajairwa cache maitiro eiyo classic processors mumashandisirwo avo.
