87 jguarin2002 5337d 09h /jart/trunk
42 Counters and Modulo 0 detectors, used by the ray generators. jguarin2002 5401d 10h /jart/trunk
41 Now scan is fully merged in the powergrid cells jguarin2002 5401d 10h /jart/trunk
40 The song remains the same jguarin2002 5401d 11h /jart/trunk
39 The song remains the same jguarin2002 5401d 11h /jart/trunk
38 Library additions make in order to support signed addition. jguarin2002 5401d 11h /jart/trunk
37 Minor width parameters name change.

Scan Out support.

Register constant value parameter at cell exit. If contant value input to the cell doesn't go out, this is useful for the last grid in the array grid and saves some registers.

K now flows upwards to: a K pipe flowing to the distance comparison row was added.		 jguarin2002 5401d 11h /jart/trunk
36 Minor width parameters name change. jguarin2002 5401d 11h /jart/trunk
35 Everything is going to the same directory.... jguarin2002 5401d 11h /jart/trunk
34 + rayxsphereGrid.vhd :

RayxsphereGrid is a grid built on floor0Row floor1Row and floor2Row blocks.

+ gridCube.vhd :

gridCube is a cube built on top of rayxsphereGrids....
gridCube intention is to scale a single rayxsphereGrid perfomance.		 jguarin2002 5406d 02h /jart/trunk
33 - Wrote some comments.
- The Power Grid Package is finished!. Though... it should be called Power Cube Package.		 jguarin2002 5406d 02h /jart/trunk
32 Added floor2Row.vhd

Some changes pro code legibility.		 jguarin2002 5409d 17h /jart/trunk
31 A more comprehensive scan chain. jguarin2002 5410d 05h /jart/trunk
30 floor1Row.vhd: an entire K comparison cells row, with parameterizable number of cells. jguarin2002 5411d 22h /jart/trunk
29 kComparison signal control added. jguarin2002 5411d 22h /jart/trunk
28 Ray Intersection Test, Pipe enable clock. jguarin2002 5411d 22h /jart/trunk
27 GPL License. And comments removed. jguarin2002 5411d 23h /jart/trunk
26 Independent "row through" signals for each cell in the row. jguarin2002 5411d 23h /jart/trunk
25 floor0Row : an entire dot product cell rows. With parameterizable cell numbers. jguarin2002 5411d 23h /jart/trunk
24 Typos...... jguarin2002 5412d 01h /jart/trunk
23 A 1 stage pipe 3 operand simultaneous adder, with parameterizable width. jguarin2002 5412d 02h /jart/trunk
22 Package file declarations :

Declared component for arithmetic functions.		 jguarin2002 5412d 03h /jart/trunk
21 A 1 stage minimun distance comparer.

This block turns out to be a collection of instances:

{LT+SCANFFx2}		 jguarin2002 5412d 03h /jart/trunk
20 I must check that there are no latches inferred in what I want to be DFF with enable signals.

The 1 stage pipe K comparison cell.		 jguarin2002 5412d 03h /jart/trunk
19 Added some control signals.
Added a 3 operands 36 bits adder (12 ns)-> 1 stage pipe.
Added a 18x18 bits multiplier (10 ns) -> 1 stage pipe.
So... the dot cell goes upwards on a two stage pipe:

STAGE1:{M(2,18)P1x3} STAGE2:{A(3,36)P1x1}		 jguarin2002 5412d 03h /jart/trunk
18 The GPL license. jguarin2002 5425d 08h /jart/trunk
17 GPL license and Julian Guarin Authoring Copyright. jguarin2002 5425d 08h /jart/trunk
16 Intersection Test Package file. jguarin2002 5425d 08h /jart/trunk
15 Some clarification jguarin2002 5425d 08h /jart/trunk
14 This is the ray tracing main block. The 3 level sphere ray intersection grid. jguarin2002 5425d 13h /jart/trunk
