v0.7.1

This is an incremental release:

• Support for rectangular convolutions
• New Timeloop configurations included in repo
• Area improvements for runtime-configurable dataflows
• Faster build and elaboration times

v0.7.0 I-BERT, Chipyard 1.8, and new profiling scripts

• Add support for I-BERT, including its I-GELU, layernorm, and softmax variants
• Add new parallelized profiling and data collection scripts
• Support for Chipyard 1.8
• Miscellaneous area, power, perf, and functionality improvements, as well as bug fixes

v0.6.4 Dummy configs, area improvements, and bug fixes

New features:

• Add support for new "dummy configs" which give cycle-accurate performance results, but which don't guarantee functional correctness of matmul/conv operations
• Optimize area for reservation stations by splitting unified reservation station into separate stations for each instruction type

Bug fixes:

• Fix incorrect assertions from firing when building some non-systolic configs
• Fix unpredictable infinite stall caused by OS interrupts
• Fix build scripts when building simulators that can generate waveforms

v0.6.3 Chisel 3.5 Bump and Depthwise Convolution Fixes

• Bump to Chisel 3.5
• Fix bug with depthwise convolutions

v0.6.2 Proxy Kernel and Floating Point Fixes

• Disable on-demand paging for proxy-kernel workloads, because on-demand paging doesn't work well with large binaries
• Fix compilation errors for large floating-point configs

v0.6.1 New Usability Improvements

• New scripts to run proxy-kernel binaries on Gemmini
• Better help messages in Gemmini convenience scripts
• New setup and quick start instructions in Gemmini's README

v0.6 Training Features and Performance/Area/Energy Optimizations

• Support for various convolutions that occur during back-propagation
• Single-porting config options for scratchpad/accumulator
• Tree-reduction pipelining options for spatial array
• New SoC and simulation counters that give insight into the performance of Gemmini accelerators and other SoC components
• New scripts that make it easier to build and test Gemmini configs.

v0.2 Padding, Banked Accumulators, Unrolled mvin/mvout

• Hardware-supported padding for matrices which are not multiples of the array size
• Banked accumulators
• Loop unrolled mvin/mvout for matrix sizes divisible by the size of the array
• Bug fixes
