Function Documentation

check_result()

uint32_t check_result	(	uint32_t	num,
		uint32_t	opa,
		uint32_t	opb,
		uint32_t	ref,
		uint32_t	res
	)

Check results (reference (SW) vs actual hardware).

Parameters

[in]	num	Test case number
[in]	opa	Operand 1
[in]	opb	Operand 2
[in]	ref	Software reference
[in]	res	Actual results

Returns

zero if results are equal.

main()

int main

(

void

)

Main function; test all available operations of the NEORV32 'B' extension using bit manipulation intrinsics and software-only reference functions (emulation).

Note

This program requires the bit-manipulation CPU extension.

Returns

Irrelevant.

print_report()

void print_report	(	int	num_err,
		int	num_tests
	)

Print test report.

Parameters

[in]	num_err	Number or errors in this test.
[in]	num_tests	Total number of conducted tests.

xorshift32()

uint32_t xorshift32

(

void

)

Pseudo-Random Number Generator (to generate deterministic test vectors).

Returns

Random data (32-bit).
