ABP wrapper/ resizer 32-128 bit FPGA SoC

The design is implemented on a System On Chip (SoC) The processor is Cortex-M3 32-bit which is interfaced to an FPGA fabric where a processing of some variables will take place. The variables are sent...
AMBA APB

1)what is the difference between with wait state and with no wait state(read/write)?what are the advantages of both in APB?
AMBA APB

1) the APB uses massive memory-I/O accesses.what is that massive memory-I/O accesses?
AMBA 3 APB PENABLE wrt PREADY

Hi, I need a clarification on PENABLE with respect to PREADY. 1) Can pready remain high for more than one cycle? 2) Does PENABLE from the master has to look for PREADY going low to deassert or it...
[APB] Assert timing of PSTRB and PPROT

Hi All, I have a question about assert timing of PSTRB and PPROT. I think APB4 spec (IHI0024C_amba_apb_protocol_spec.pdf) does not describe when PSTRB and PPROT should be asserted. I guess these signals...
