C2000-CGT

This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.

Description

The TI C2000 C/C++ Compiler and Assembly Language Tools support development of applications for TI C2000 Microcontroller platforms, including the Concerto (F28M3xx), Piccolo (280xx), Delfino Floating-Point (283xx), and C2000 Fixed-Point (2823x/280x/281x) Microcontroller devices.

Features

• Available in release 20.12.0.STS:

  • Live Firmware Update feature for C28/CLA firmware update support
  • Generate CRCs over memory ranges
  • C28 has more efficient data accesses for lower 16-bits of memory when using location attribute or literal addresses.
  • The Integer Division Unit (--idiv_support=idiv0) has performance updates.
  • CLA has a performance improvement with more efficiently loading 16-bit constants.
  • Enumerated type changes.
  • Misra support deprecated
• Available in release 20.2.0.LTS:
• Hex utility tool new option --cmac (cipher-based message authentication protocol) will apply cmac algorithm to user defined regions and generate cmac tags for secure boot support.
• The Integer Division Unit (--idiv_support=idiv0) has performance, diagnostic, and build attribute updates.
• Memcpy inlining with RPT now supported for more than 255 words (up to 65535).
• FPU64 RTS library trig float routines sinf/cosf/tanf/cbrtf are now the same for fpu32 and fpu64 --float_support modes.
• New diagnostic checks were added for: block/non-blocked access, function calls between c28/cla code, FPU64 assembler checks, and --advice:performance for fpu32/fpu64.
• VCU register save/restore support for ISRs with --isr_save_vcu_regs option.

Long-term and short-term support

Long-term support (LTS) releases are actively maintained for approximately two years with reported defects being repaired as follows:

• Production stop defects are addressed within 2 weeks,
• Critical defects are addressed within 90 days, and
• Defect repairs are proactively applied to each release stream

• Only production stop defects may cause patch releases to be created,
• Patch releases for STS releases will not be planned, and
• Defect repairs will not be proactively applied to each release stream
• For more information about the distinction between LTS and STS compiler releases, please see the article: Introduction to LTS and STS Compiler Releases
