Note: Since an interrupt is generated 80 times, the first read to internal RAM (which requires 1 additional state) occurs
Sample 1: Calculation example for CPU + HDMA
Conditions:
Calculation example:
Transfer count
80 times, requiring additional 80 states in total. In addition, from bus REQ to bus ACK, an overhead time of 2
states is also needed for each interrupt request, requiring additional 160 states in total.
follows:
16 (64 bytes/4 bytes = 16 times) and counter B is set to 80.
CPU operation speed (f
I2S sampling frequency : 48 KHz (60 MHz/25/50 = 48 KHz)
I2S data transfer bit length
DMAC channel 0 used to transfer 5 Kbytes from internal RAM to I2S
DMAC source data read time:
DMAC destination write time:
To transfer 5 Kbytes of data in 4-byte units, the transfer count is calculated as
5 Kbytes/4 bytes = 1280 [times]
Since I2S generates an interrupt for every 64 bytes, the DMAC’s counter A is set to
t
HDMA start interval [s] = 1 / I2S sampling frequency [Hz] × (64 / 16 )
CPU bus stop rate = t
STOP
Internal RAM data read time
= 1 state/4 bytes (However, the first 1 byte requires 2 states.)
I2S register write time = 2 states/4 bytes
(HDMA) = (((1 + 2) × 16) × 80) + 80 + 160) / f
