conspiracion/rtl/core/alu/shifter.sv, branch master Linux-capable SoC platform with a custom ARMv4 quad-core SMP CPU, coherent caches, and a 3D graphics accelerator. Synthesizes for Terasic DE-series FPGA boards. Simulated with Verilator. Major shifter-ALU redesign 2022-10-02T15:49:48+00:00 Alejandro Soto alejandro@34project.org 2022-10-02T15:49:48+00:00 e97d445908f39a3a1a215a824f52b283147e6195 The shifter unit now works in parallel with the ALU and is no longer part of it. Instructions that use the shifter as input to the ALU will now take an additional cycle, unless the control unit can detect a "trivial shift" situation where the shifter's output will be the same as its input. This change improves Fmax substantially.
