Consequently, the dual-core Xilinx Zynq All Programmable SoC uses an ARM Generic Interrupt Controller (GIC) to process interrupts, which can come from:

  • Software-Generated Interrupts – 16 for each processor. Software-generated interrupts can interrupt themselves and either or both processors.
  • Shared Peripheral Interrupts – 60 in total. These interrupts can come from the I/O Peripherals in the Zynq SoC’s Processor System (PS) or from the Programmable Logic (PL) side of the device. The two ARM Cortex-A9 MPCore CPU’s share these interrupts.
  • Private Peripheral Interrupts – 5 interrupts, which are private to each CPU (e.g. CPU timer, CPU watchdog timer, and dedicated PL-to-CPU interrupt).

セブンオブナインです。Unimatrix 01の第三付属物 9の7という識別番号です。Star trek Voyagerの好きなキャラクターです。まとめ記事は後日タイトルから内容がわからなくなるため、title検索で見つかるよう個々の記事にしてます。いわゆるBorg集合体の有名なセリフから「お前たち(の知識)を吸収する。抵抗は無意味だ」。Thanks in advance.
