+ Abstract
+
+ "The objective of this work is to design and implement a TAP controller IP core compatible with IEEE 1149.1-2013 revision of the standard. The test logic architecture also includes the Test Mode Persistence controller and its associated logic. This work is expected to serve as a ready to use module that can be directly inserted in to a new digital IC designs with little modifications."

# RISC-V Instruction Set Architecture
**PLEASE UPDATE** - we are no longer implementing full RISCV, only user-space
* [RISC-V Supervisor Binary Interface Specification](https://github.com/riscv/riscv-sbi-doc/blob/master/riscv-sbi.md)
Note: As far as I know, we aren't using the RISC-V V Extension directly
-at the moment. However, there are many wiki pages that make a reference
+at the moment (correction: we were never going to). However, there are many wiki pages that make a reference
to the V extension so it would be good to include it here as a reference
for comparative/informative purposes with regard to Simple-V.
