  • Commit GSI patches from Wesley Terpstra

    - Add JTAG capture pin
    ==> allows removing sensitivity to reg_update which caused clocking problems making JTAG unstable
    - Use register file backed by RAM blocks
    ==> saves quite some area and speed on altera
    ... be sure to enable it using `define CFG_EBR_POSEDGE_REGISTER_FILE
    - Fix a minor problem where compilation fails when interrupts are not supported
    - Add support to flush icache and dcache per JTAG
    - Fix wrong width assignments for PC

    Multiplier patch has been left out for now; don't the design synthesizers (Quartus / Xst) split the multiply automatically?

reduce size of caches to fit in DE1 FPGA

  • Mon, 05 Apr 2010 21:00:31 +0100
  • by Philip Pemberton <philpem@philpem.me.uk> [Mon, 05 Apr 2010 21:00:31 +0100] rev 6
  • reduce size of caches to fit in DE1 FPGA

    The default cache size makes the Icache and Dcache "just a bit" too big to
    fit in the EP2C20 FPGA on the DE1 board. This commit reduces the Icache and
    Dcache sizes to the defaults shown in the LatticeMico32 Processor Reference
    Manual (pages 36 and 37).

  • by Philip Pemberton <philpem@philpem.me.uk> [Sun, 04 Apr 2010 20:52:32 +0100] rev 2
  • Disable Lattice-specific stuff by default

    To build on Lattice platforms, `define PLATFORM_LATTICE in lm32_include.v.
    Otherwise, non-optimal "platform independent" HDL will be used.
    This means LM32 can now be built for non-Lattice FPGAs.
