From c72e3ad5824eb9385b62a51633cff817b825f06d Mon Sep 17 00:00:00 2001 From: Pavel Pisa Date: Tue, 26 Mar 2019 23:40:21 +0100 Subject: Change single cycle core with delay slot to use separate fetch stage. When instructions are visualized then it is even more misleading to keep old instruction in decode phase delay buffer. The single cycle core with delay slot is upgraded to the variant with fetch and execute phases. This way the structure is logical and delay slot has purpose.
