Honored ContributorCyclone V SoC doubt
Hi, I will have to program a RISC-V processor and I wanted to know if it's possible to access to ARM Cortex-A9 L1 and L2 caches or if I will have to use FPGA memory as cache. Also, I wanted ...

Honored Contributor --- Quote Start --- A SOC FPGA is just a hybrid combination of a CPU device and an FPGA device. There have been standalone ARM CPU chips for quite a while, as well as FPGA devices. The SOC (system on chip) basically just merges together a dual core ARM CPU chip and an FPGA (it is actually a lot more complex than that, but if you squint at a block diagram that is what it looks like). ARM is the CPU of choice for SOCs (both Intel/Altera and Xilinx) because of the nature of ARM Co's business model of initially supplying design IP to customers rather than silicon devices. ARM also more or less has a lock on 'pure' SOC devices like those from Broadcom (think Raspberry PI) and Qualcomm (think Android smartphones). --- Quote End --- Thank you so much.
