Merge pull request #1 from supleed2/alu 
Alu MUL, MLA and MLS fixed. LUT in multiply block fixed.
 2020-06-09 20:35:41 +01:00
Aadi Desai fefcad13ce Updated alu to feed only positive values to multiply block 
When both values are positive/negative the positive result from the multiply block is correct. When only one is negative, the result is inverted.
 2020-06-09 20:34:29 +01:00
Aadi Desai 12da9b94a5 Updated LUT to have an unregistered output 
Allows Multiply block output to be valid after 1 clock cycle rather than 2

Kacper 3d9ea175cd Working on debugging 
The multiplier uses a 2 port ROM. For some reason, I cannot generate one on my machine and so I cannot change the exusting LUT ROM to remove the register outputs. If someone else can do it (Ben), that would be great.

Aadi Desai 94124c5a0e
Update LIFOstack to support 32 memory slots 
Also fixed typo on line 15, previous version had a pointer for 16 slots but the memory register only had 4 slots

Kacper 42739283f5 Update .gitignore 2020-06-07 17:45:40 +01:00
Kacper 24e22f13ec Fixed instrGen and added large test 
Also added a note about the OR instruction. Either to fix later or leave as is.

Kacper 685f69a7cf Almost ready CPU 
Changed the MUX blocks into Verilog just cuz they look neater and are probably more optimised in the end. Added the LIFO stack. Working on decoder logic.

Aadi Desai 3f0c91b0ff
Initial ALU Verilog 
Currently using incorrect implementation for Multiply (* operator), to be fixed once Multiply method is decided

Benjamin Ramhorst fedfcaaada
Added most of the code for generating the instruction MIF. Still need to do a big if-else statement for every instruction. 2020-05-28 14:42:02 -07:00
ben 3d6e456fcc Almost completed 16 bit multiplier. 2020-05-28 15:02:22 -07:00
ben e39d2f653a Started working on the multiply block. Added absolute value block. 2020-05-28 09:11:14 -07:00
