Niels Moseley	10d9735e11	First working simulation of 'hello, world' :)	2017-10-24 21:49:05 +02:00
Niels Moseley	31163effd9	Updated filter engine FSM to have named states and separated clocked and non-clocked processes. Fixed bug in spmul which caused incorrect sign handling in final product	2017-10-24 19:40:56 +02:00
Niels Moseley	22b3443358	Fixed python script to generate sign-magnitude coeffs instead of 2s complement ones. Filter engine FSM needs revisiting.	2017-10-24 00:34:54 +02:00
