ITPGotta clear up on this.. when was tap/itp/xdp used/dropped Intel processors do not support early JTAG, such as 286,386,486 EX, etc., starting from the Pentium, Intel CPU also started adding support for JTAG, but that interface is called ITP (In Target Probe), a 25-pin dual in-line interface , PCB Layout was due to space constraints, they were more defined space-saving ITP700Flex interface signal definitions are the same but with a smaller connector package. XDP从Intel Core CPU 开始，随着调试复杂度的增强，在ITP 的基础上， Intel 定义了一个新的调试接口叫XDP, (eXtend Debug Port), 标准封装模式为60Pin， 也同时定义了几种不同的小封装连接器形式，比如SSA (31pin), SFF 24, SFF 26 等。 From the Intel Core CPU, with the complexity of debugging enhancements, based on the ITP, Intel defined a new debug interface called XDP, (eXtend Debug Port), standard package model 60Pin, also defines several different connector in the form of small packages, such as SSA (31pin), SFF 24, SFF 26 and so on.其 实现在BIOS Developer 说的ITP 或者XDP, 其实是指支持ITP / XDP 接口的Intel CPU 仿真器， 而且习惯统称为ITP, 但是实际上是有ITP/ XDP 之分的， ITP 只支持Pentium II, Pentium III, Pentium 4, Pentium Mobile, Celeron D, Coleron M 等Intel IA32 Processors, 但是XDP 是用来支持Intel Core, Core 2 Duo, Nehalem, Sandy Bridge and future processor architecture. In fact, now that the BIOS Developer ITP or XDP, in fact, is to support ITP / XDP interface Intel CPU emulator, and used collectively referred to as ITP, but in fact there is ITP / XDP of the points, ITP supports only Pentium II, Pentium III , Pentium 4, Pentium Mobile, Celeron D, Coleron M and other Intel IA32 Processors, XDP, but is designed to support Intel Core, Core 2 Duo, Nehalem, Sandy Bridge and future processor architecture.
