The SDRAM reads/writes occur at 64 bits so when you read from SDRAM into SDRAM transfer regs the 64 bit data will be copied into two contiguous SDRAM transfer registers(32x2) automatically. I hope this answers your question I had done using Microcode.
Hi, I am experimenting with uC_lab1 project from the SDK. When a packet is copied from the rfifo to the sdram, I want to read that packet data from the sdram address to sdram read register. Since a single sdram address contains 64 bit data and an sdram read register is 32 bit, how can I read the whole 64 bit data to sdram registers?
I tried using this intrinsic:
void sdram_read(__declspec(sdram_read_reg) void *data, volatile void __declspec (sdram) * address, unsigned int count, queue_t queue, sync_t sync);
I can't understand how to declare the "data" parameter as the reference says it's a structure.
Please help.
