199 Massive specification rewrite, brings it up to date with the current ZipCPU
state. This does not reflect any major change to the CPU.
dgisselq 2961d 21h /zipcpu/
198 Added a copyright notice. dgisselq 2963d 02h /zipcpu/
197 Added a new multiply testbench. Other changes were necessary to follow. dgisselq 2963d 02h /zipcpu/
196 Updated internal documentation. dgisselq 2963d 02h /zipcpu/
195 Adds a new mode that can handle a delayed stall signal. dgisselq 2963d 02h /zipcpu/
194 Cleaned up some parameters, trying to create more consistency. dgisselq 2963d 02h /zipcpu/
193 These changes make it so the ALU multiplies pass a test-bench. dgisselq 2963d 02h /zipcpu/
192 Fixed a bug with constant alignment in the assembler. dgisselq 2963d 02h /zipcpu/
191 Updated toolchain, more information on the example debugger. dgisselq 2978d 05h /zipcpu/
190 Added the copyright statement back in. dgisselq 2979d 21h /zipcpu/
189 Final, as delivered, ORCONF slides. dgisselq 2979d 21h /zipcpu/
188 Adjusted the opcodes to match the binutils port: added RTN instructions, and
allowed BREAK instructions to include an immediate--to be interpreted by the
debugger.
dgisselq 3011d 23h /zipcpu/
187 Updated to match changed register definitions within the core. dgisselq 3012d 00h /zipcpu/
186 Now allows profile dumping for ELF executables. dgisselq 3012d 00h /zipcpu/
185 Now includes the proper flags for building with ELF executable file support. dgisselq 3012d 00h /zipcpu/
184 Adjusted the illegal instruction option documentation. dgisselq 3012d 00h /zipcpu/
183 Cleaned up the system so that !CYC implies !STB as well. dgisselq 3012d 00h /zipcpu/
182 Bug fix for fast memories. This now works for memories with single cycle
latencies.
dgisselq 3012d 00h /zipcpu/
181 Adjusted the wishbone logic to include our wishbone simplification that if
CYC is ever low, STB must be low as well.
dgisselq 3012d 00h /zipcpu/
180 Cleaned up the stall logic--made it independent of whether or not we are
designed to be alternating or not.
