Just as in Win32, the addressable range is divided into user and kernel mode areas. Each process gets its own unique 8TB at the bottom end, while kernel mode code lives in the upper 8 terabytes and is shared by all processes. The different versions of 64-bit Windows have different ...

The RAM address space is used for variables, register banks, the system stack, the PEC pointers (in 00'FCE0h - 00'FCFFh) and the bit-addressable space (in 00'FD00h - 00'FDFFh). 00'EFFFh 256 Byte RAM/SFR XSSP 00'FFFFh 00'F000h 00'FF3Fh 00'FF20h SFR Area 00'FFFFh 00'EF00...

It is functionally compatible with the industry-standard 80C52 microcontroller series, except that one extra 4-bit bit-addressable I/O port(Port 4) and two additional external interrupts (INT2 , INT3 ). The W78E58 contains four 8-bit bi-directional and bit-addressable I/O ports, three 16...
The increased data bus width enables support for addressable memory space above the 4GB generally available on 32bit architectures. 增加的数据总线带宽实现了对32位架构上通常可用的4GB以上可寻址内存空间的支持。 www.ibm.com 5. J9 was originally designed for 32bit systems and this influenced some of ...
The next 16bytes above the register banks form a block of bit-addressable memory space. The 8051 instruction set includes a wide selection of single-bit instructions, and the 128 bits in this area can be directly addressed by these instructions. The bit addresses in this area are 00H ...
Performance is also the core reason why a bool is not a single bit. There are few processors that make a bit directly addressable, the smallest unit is a byte. An extra instruction is required to fish the bit out of the byte, that doesn't come for free. And it is never atomic. ...
A register bank can consist of up to 16 word-wide (R0 to R15) and/or byte-wide (RL0, RH0, …, RL7, RH7) General Purpose Registers (GPRs). The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR, any location in the DPRAM is bit addressable. Data ...
