**Impact on processor**:
```
- TODO
+ Addition of new Load/Store Fixed and Floating Point instructions
```
**Impact on software**:
**Motivation**
-
+Moving the update of RA to *after* the Memory operation saves on instruction count
+both outside and inside hot-loops. strncpy may be reduced to 11 Vector instructions,
+3 of which are the zeroing loop, 5 of which are the copy. Percentage-wise LD/ST
+Update Post-Increment represents a massive 20% reduction.
**Notes and Observations**:
+These types of instructions are already present in x86 (sort-of).
+* x86 chose that store should be pre-indexed and load should be post-indexed
+* Power ISA chose everything to be pre-indexed
+* Motorola 68000 (decades old) has pre- and post- indexed

-The following instructions are proposed to be added in EXT2xx,
-duplicating LD/ST-Update functionality but moving the update
-of RA to *after* the Memory operation. These types of
-instructions are already present in x86 (sort-of).

-* x86 chose that store should be pre-indexed and load should be post-indexed
-* Power ISA chose everything to be pre-indexed
-* Motorola 68000 (decades old) has pre- and post- indexed

The LD/ST-Immediate-Post-Increment instructions are all Primary
Opcode: there are 13 of these. LD/ST-Indexed-Post-Increment
are all effectively 9-bit XO and consequently may easily
