Make cache 2-way associative

  • Tue, 06 Apr 2010 18:27:55 +0100
  • by Philip Pemberton <philpem@philpem.me.uk> [Tue, 06 Apr 2010 18:27:55 +0100] rev 7
  • Make cache 2-way associative

    Switched from Direct Mapped to 2-Way Set Associative caches. Should boost speed
    a bit.

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).

disable caches, they use too much RAM :(

remove more Lattice-specific fluff

  • Sun, 04 Apr 2010 22:05:07 +0100
  • by Philip Pemberton <philpem@philpem.me.uk> [Sun, 04 Apr 2010 22:05:07 +0100] rev 3
  • remove more Lattice-specific fluff

    Code now synthesizes properly on Altera Quartus 9.0 build 235

Disable Lattice-specific stuff by default

  • Sun, 04 Apr 2010 20:52:32 +0100
  • 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.
