Introduction

The MMALIB package consists of the Texas Instruments optimized kernels for CNN, DSP and LINALG algorithms.

Licensing

The licensing information of this library and a complete manifest along with export control information is detailed here [HTML].

Getting Started

The MMALIB User Guide [USER_GUIDE] provides the documentation and references necessary to begin development on TI's platforms.

What's New

Here are the new features supported in this release:

[MMALIB-1410] Matrix-matrix-multiply Bias optimizations when scale shift and bias are constant

[MMALIB-1421] Matrix-matrix-multiply Bias optimizations to leverage subpaneling of matrix multiplies

[MMALIB-1394] Tensor convert support for INT32/UINT32 inputs and outputs

Validation Information

This release was built and validated using the following tools:

Build Tools (NOT included in MMALIB):

C7x CGT C7000-CGT-5.0.0 LTS

Fixed Issues

[MMALIB-1441] src2_addr.stride_y parameter ignored in MMALIB_LINALG_matrixMatrixMultiplyBias_ixX_ixX_oxX_exec (prevents external broadcast by setting stride_y to 0)

Known Issues

[MMALIB-571] MMALIB_CNN_convolveBias_row_ixX_ixX_oxX_exec_cn: May produce wrong last row when padBottom = 1
[MMALIB-612] MMALIB_CNN_pixelShuffle_row_ixX_ixX_oxX: Divergent behaviour between NatC and CI mode when execInArgs set
[MMALIB-632] MMALIB_CNN_convolve_col_smallNo_ixX_ixX_oxX: add checkParams case for checking space allocated for virtual group to make an even number of groups when stride == 2
[MMALIB-986] MMALIB_CNN_pixelShuffle_row_ixX_ixX_oxX: Code regarding MBlocksFlag = 1 is unreachable in Nat C given restriction that subMChannels must equal No
[MMALIB-1324] [MMALIB_CNN_fullyConnectedBias_ixX_ixX_oxX] Missing checkParams on input/output geometries
[MMALIB-1558] Tensor convert stride y value not considered within checkParams against dim_x

Deprecation

MMALIB_CNN_convolve_col_smallNo_legacy_ixX_ixX_oxX

Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit	Meaning	Description
1 (M=Major)	Major revision	Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor)	Minor revision	Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch)	Patch number	Incremented for all other source code changes. This include any packaging support code.
4 (b=build)	Build number	Incremented for each release delivery to CM. Reset for any change to M, m or p
