Detailed Description

True random number generator demo program.

Author: Stephan Nolting

Function Documentation

◆ adaptive_proportion_test()

void adaptive_proportion_test ( void )

Run adaptive proportion test (NIST SP 800-90B)

◆ aux_print_hex_byte()

void aux_print_hex_byte ( uint8_t byte )

Print HEX byte.

Parameters

[in] byte Byte to be printed as 2-char hex value.

◆ compute_rate()

void compute_rate ( void )

Compute average random generation rate

◆ delay_ms()

void delay_ms ( uint32_t time_ms )

Simple bus-wait helper.

Parameters

[in] time_ms Time in ms to wait (unsigned 32-bit).

◆ generate_histogram()

void generate_histogram ( void )

Generate and print histogram. Samples random data until a key is pressed.

◆ irq_test()

void irq_test ( void )

Test TRNG interrupt.

◆ main()

int main ( void )

Simple true random number test/demo program.

Note: This program requires the UART and the TRNG to be synthesized.

Returns: 0 if execution was successful

◆ print_hex()

void print_hex ( void )

Print random numbers as HEX dump.

◆ print_random_data()

void print_random_data ( void )

Print random numbers until a key is pressed.

◆ repetition_count_test()

void repetition_count_test ( void )

Run repetition count test (NIST SP 800-90B)

◆ trng_firq_handler()

void trng_firq_handler ( void )

TRNG interrupt handler.
