The ARM Cortex-A57 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings. The Cortex-A57 is an out-of-order superscalar pipeline. [ 1 ] It is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores (e.g. GPU , display controller , DSP , image ...
The UVD 2.2 features a re-designed local memory interface and enhances the compatibility with MPEG2/H.264/VC-1 videos. However, it was marketed under the same alias as "UVD 2 Enhanced" as the "special core-logic, available in RV770 and RV730 series of GPUs, for hardware decoding of MPEG2, H.264 and VC-1 video with dual-stream decoding".
This table illustrates an example of an 8 bit signed decimal value using the two's complement method. The MSb most significant bit has a negative weight in signed integers, in this case -2 7 = -128. The other bits have positive weights. The lsb (least significant bit) has weight 1. The signed value is in this case -128+2 = -126.
In order to do so, the CPU has a full 24-bit address mode called ADL mode. In ADL mode, all Z80 16-bit registers are extended to 24 bits with additional upper 8-bit registers. For example, the HL register pair is extended with an uppermost register called HLU. The resulting 24-bit multi-byte register is collectively accessed by its old name, HL.
This is a table of 64/32-bit central processing units that implement the ARMv8-A instruction set architecture and mandatory or optional extensions of it. Most chips support the 32-bit ARMv7-A for legacy applications.
General home computing and gaming utility emerged at 8-bit word sizes, as 2 8 =256 words, a natural unit of data, became possible. Early 8-bit CPUs (such as the Zilog Z80 and MOS Technology 6502, used in the 1977 PET, TRS-80, and Apple II) inaugurated the era of personal computing. Many 16-bit CPUs already existed in the mid-1970s.
The Cortex-A53 is a 2-wide decode superscalar processor, capable of dual-issuing some instructions. [1] It was announced October 30, 2012 [ 2 ] and is marketed by ARM as either a stand-alone, more energy-efficient alternative to the more powerful Cortex-A57 microarchitecture, or to be used alongside a more powerful microarchitecture in a big ...
