Embodiment 1

[0030] An embodiment of the present invention provides a fixed-floating-point arithmetic device, such as figure 1 and figure 2 As shown, the fixed-floating-point computing device includes: a data receiving port 1 for receiving a logic control signal group (ctrl) and an operand. According to different computing requirements, the control signals actually sent by the logic control signal group are also different, and According to different calculation requirements, the number of operands received by the data receiving port 1 can be one or more, it can be a scalar floating-point number, a vector floating-point number, or a vector fixed-point number, etc.; the operation module 2. It is used to perform operations on the operands according to the logic control signal group to generate operation results. The above-mentioned operation module 2 may include a basic operation module 21, a leading zero statistics module 22, a shift module 23, a number statistics module 24 of 1, a floating...

Abstract

The invention provides a fixed-floating-point operation device which comprises a data receiving port which is used for receiving a logic control signal group and an operand; an operation module used for carrying out operation on the operands according to the logic control signal group to generate an operation result; a latch used for managing the concurrent access to the shared resources; and a first multiplexer used for selecting and outputting the operation result. According to the device, a plurality of operation modules with different functions are integrated, different operations on operands can be realized according to the received logic control signal group, and a required operation result is selectively outputted through the first multiplexer. The fixed-floating-point operation device provided by the invention is embedded in the processor, so that the functional integrity of the processor is realized.

Description

technical field [0001] The invention relates to the field of computer floating-point calculations, in particular to a fixed-floating-point calculation device. Background technique [0002] With the increasingly extensive calculation-intensive requirements and the sharp increase in computational complexity, SIMD (Single Instruction Multiple Data) vector calculations in microprocessors are also widely used, which improves the real-time performance of microprocessor data processing. [0003] In the process of realizing independent, safe and controllable processor localization, due to foreign technology monopoly and sales ban, high-performance floating-point computing units need to be independently developed and verified. However, the self-developed floating-point computing unit in the prior art has a single function, and it is impossible to realize multiple floating-point operations in one fixed-floating-point computing device. Contents of the invention [0004] Therefore, t...
