What is the core difference between HCS12 and HC12 series???? hi Sameer Deshmukh Here is an overview of the HCS12 CPU architecture. The HCS12 CPU is identical to the MC68HC12 and is referred to in most documents as CPU12. Another factor to consider is that CPU12 is upward compatible with the MC68HC11 CPU. respectively in this module. Like the HC12, the HCS12 CPU maps all registers and peripherals into a single linear address space, providing efficient memory access. Since the HCS12 family supports up to 1 mega byte of address space, a paging scheme has been implemented to access as many as 64-16K page windows. This provides system designers with the memory needed to satisfy many applications. The HCS12 CPU instruction set extends the HC11 instructions for data movement, data manipulation, enhanced arithmetical operation, and branching and control logic. In addition, the HCS12 model adds several new addressing modes for a total of sixteen addressing modes. Although most of the HCS12 family members have on-chip Flash and RAM, which are ideal for single chip solutions for many applications, the system designer can configure the device to access additional memories externally. The HCS12 has an identical programmers model to M68HC11/M68HC12 No new registers No changes in interrupt stacking order Muxed and non-muxed external interfaces The HCS12 can reuse existing software source code. - Note: timing loops change due to new clock frequency, Byte counts and instruction cycle times. The HCS12 has improved performance when using new instructions. The HCS12 reduces interrupt latency. The HCS12 increases math speed. The HCS12 increases performance. Instruction queue data increases performance Instructions execute faster while remaining deterministic Added instructions designed with compilers in mind: The new instructions and addressing modes support high level languages. MC68HC12 and HCS12 have an identical instruction set. Stack pointer and program counter offset indexed addressing 11 math instructions Fuzzy logic instructions Long branch instruction (16 bit offset) Move instruction (memory to memory) Min / max functions Bit manipulations for entire memory map Exchange / transfer Table look-up and interpolate function Looping construct The CPU12 is a high-speed, 16-bit processing unit. It has full 16-bit data paths and internal registers for high-speed extended math instructions. The instruction set is a proper superset of the M68HC11 instruction set. The CPU12 allows instructions with odd byte counts, including many single-byte instructions. This provides efficient use of ROM space. An instruction pipe buffers program information so the CPU always has immediate access to at least three bytes of machine code at the start of every instruction. The CPU12 also offers an extensive set of indexed addressing capabilities. The HCS12 includes new instructions and addressing modes to support high level languages. There are a number of features included in the HCS12 CPU for efficiently implementing code that is written in a high-level language. CPU12 has a full set of 8 and 16-bit mathematical instructions such as 16x16 signed and unsigned multiplies and divides. CPU12 also includes a set of efficient fuzzy logic instructions, and table lookup and interpolate. It also includes many instruction that support looping construct.

The HCS12 and HCSX do provide pin compatable devices. However, my HCS12
Cosmic/Multilink tool chain does not regcognize the HCSX version. Now the
sob story for me was that I was attaracted to the HCSX12 offer of more
serial ports, this means a complete compiler/programmer procurement just to
support 2 more serial ports using the HCSX with my existing design - how
obsurd, it was misleadingly advertized as a plug and go, NOT !! I need to
now pay thousands of dollars for XGATE functionality and to make the Zap
debugger working for HCSX (excluding XGATE), that I dont really need. Cosmic
could have offered a simple upgrade (excluding XGATE) a kind of incremental
upgrade - but do they?
My Cosmic/Zap/Multilink tool chain only supports up to HCSDP512. I need the
additional serial ports provided by the HCSX pin compatable devices.
Can anybody perhaps coment on the Cosmic HCS compiler implementation on a
HCSX device - is it possible if not using XGATE? And how did the HCS Zap
debugger handle the HCSX device?
