Tšehetso e ntlafetseng ea Tataiso ea Litaelo tsa Phallisang
Ho v13.1, Qsys e eketsa khetho ea ho khetha karolo e ncha ea litaelo tse phaphametseng, Floating Point Hardware 2. Ho nka advantage ea tšehetso ea software bakeng sa litaelo tsa Floating Point Hardware 2, e kenyelletsa altera_nios_custom_instr_floating_point_2.h, e qobellang GCC ho bitsa newlib mesebetsi ea lipalo (ho fapana le mesebetsi ea lipalo e hahelletsoeng ka GCC). Altera e khothaletsa hore u boele u bokelle newlib bakeng sa ts'ebetso e nepahetseng.
Hlokomela: Se ke oa sebelisa khetho ea -mcustom -fpu-cfg line-line bakeng sa GCC. Khetho ena ha e tšehetse litaelo tsa Floating Point Hardware 2. Lisebelisoa tsa ho haha software ea Nios II (SBT) li eketsa litaelo tsa motho ka mong -mcustom ho etsafile ho ts'ehetsa litaelo tsa tloaelo tsa Floating Point Hardware 2.
Ts'ehetso ea ECC
Ho qala ka v13.1, mohlophisi oa paramethara ea Nios II o u lumella ho nolofalletsa ts'ireletso ea ECC bakeng sa li-RAM tse bohareng ba processor le cache ea litaelo. Ka kamehla, ECC ha e khonehe ha e seta bocha. Ka hona, software e tlameha ho nolofalletsa ts'ireletso ea ECC. Software e ka boela ea kenya liphoso tsa ECC ka har'a likotoana tsa data tsa RAM ho ts'ehetsa tlhahlobo ea mohlokomeli oa ECC le bese ea ketsahalo. The Nios II Hardware Abstraction Layer (HAL) e atolositsoe ho ts'ehetsa ho qala ha ECC le ho sebetsana le mokhelo.
Universal Boot Copier
Ho v13.1, Nios II boot copier e ntlafalitsoe ho tšehetsa mefuta e mengata ea lisebelisoa tsa flash. Sesebelisoa se ntlafalitsoeng sa boot copier se bitsoa universal boot copier. Nios II boot copier e kopitsa li-binaries tsa ts'ebeliso ho tloha lisebelisoa tsa flash ho ea mohopolong o sa fetoheng. Memori ea Flash e behiloe ka setšoantšo sa FPGA atereseng e tlase ea memori, e lateloe ke litšoantšo tsa binary tsa Nios II. Likhatisong tse fetileng tsa sehlahisoa, boholo ba setšoantšo sa FPGA bo ne bo lokiselitsoe lelapa ka leng la sesebelisoa. Leha ho le joalo, bakeng sa lisebelisoa tsa malapa a Leholiotsoana V, Stratix V, le Arria V, boholo ba setšoantšo bo fapana ho latela mefuta e latelang:
- Mofuta oa Flash: Quad-output (EPCQ) kapa single-output (EPCS) Sesebelisoa se Matlafalitsoeng sa Programmable Configuration
- Bokhoni ba sesebelisoa sa Flash: 128 kapa 256 Mbits
- Khatello
- Sebopeho sa serial peripheral interface (SPI): ×1 kapa ×4
- Sebopeho sa sesebelisoa: se le seng kapa se khaotsoe
Ho thata hore mochine oa boot o khethe motsoako oa hona joale e le hore o ka sebelisa boholo bo loketseng ba setšoantšo, 'me algorithm leha e le efe e ka' na ea hlōleha ho tšehetsa litlhophiso tsa nako e tlang. Ho rarolla bothata bona, ho eketsoa hlooho ho setšoantšo sa FPGA ho hlakisa boholo ba setšoantšo. Ka ho sebelisa boholo ba setšoantšo ho tloha hloohong, "universal boot copier" e ka sebetsana le tlhophiso leha e le efe ea flash ho lisebelisoa tsa hona joale kapa tsa nakong e tlang. Sesebelisoa sa sof2flash se nchafalitsoe ho ts'ehetsa mochini oa boot copier oa universal. Phetoho ena ha e ame bokhoni ba thibelo ea taolo ea FPGA ea ho iketsetsa setšoantšo sa FPGA ka matla.
