	k_block: Number of C values processed per one iteration of the main loop of

	requantization: name of the requantization scheme used by the microkernel.
	is_pipelined: Indicates if the micro-kernel is implemented with software
	pipelining. Additional test cases are generated for software
	pipelined micro-kernels to separately test prologue + epiloque
	of the pipelined loop and iteration of the pipelined loop.
	isa: instruction set required to run the micro-kernel. Generated unit test
