Processor Naming
Traditionally, ARM used a numbering scheme to name processors. In the early days (the 1990s), suffi xes were also used to indicate features on the processors. For example, with the ARM7TDMI processor, the T indicates Thumb instruction support, D indicates JTAG debugging, M indicates fast multiplier, and I indicates an embedded ICE module.
Subsequently it was decided that these features should become standard features of future ARM processors; therefore, these suffi xes are no longer added to the new processor family names. Instead, variations on memory interface, cache, and Tightly Coupled Memory (TCM) have created a new scheme for processor naming.

For example, ARM processors with cache and MMUs are now given the suffi x “26” or “36,” whereas processors with Memory Protection Units (MPUs) are given the suffi x “46” (e.g., ARM946E-S). In addition, other suffi xes are added to indicate synthesizable (S)(**) and Jazelle (J) technology. Table 1.1 presents a summary of processor names.

(**) A synthesizable core design is available in the form of a hardware description language (HDL) such as Verilog or VHDL and can be converted into a design netlist using synthesis software.
