Cyclone IV,V (terasic de0-nano)

요즘 막 지름신이 와서

구경하다 중고로운 평화나라에서 DE0-Nano가 있어서 보는데

막 검색을 해보니 흐음... 내가 원하는건 DE0-Nano-SoC 인 듯..

순수 FPGA 공부도 좋긴한데 고민이 되네..

(그래도 조금은 지름신님 물리쳐진듯? ㅋㅋ)

HPS 라고 해서.. ARM 코어 탑재.

이녀석이 Zynq 대응 버전이라고 보면 될려나?

Cyclone 4는 ARM 코어 없다.

음 Cyclone 4에 온칩 메모리?

최대 6.4Mb =약 800KB 인데 GX 모델로 가야지 그렇고

Cyclone IV Device Family  Features The Cyclone IV device family offers the following features:  ■ Low-cost, low-power FPGA fabric:  ■ 6K to 150K logic elements  ■ Up to 6.3 Mb of embedded memory  ■ Up to 360 18 × 18 multipliers for DSP processing intensive applications  ■ Protocol bridging applications for under 1.5 W total power

모델에 따라서 낮은건 270Kbit 이니까 34KB 부터 시작한다.

SRAM 이지 Flash는 아니었네..

Memory Modes Cyclone IV devices M9K memory blocks allow you to implement fully-synchronous SRAM memory in multiple modes of operation. Cyclone IV devices M9K memory blocks do not support asynchronous (unregistered) memory inputs.
